Mapping, recovery and remediation of arm coordination deficits after stroke. Coordination of arm movement is a significant problem after a stroke. This innovative project will underpin new treatments by focusing on what type of stroke causes difficulty in coordinating arm movement, describing the coordination difficulties in detail and investigating mechanisms of recovery and treatment.
Grafted peptide constructs - a new platform for delivering stable bioactive peptides. The project will develop a new strategy to overcome the lack of bioavailability of peptides. The project will design an effective drug delivery vehicle and facilitate drug development as highly active peptides will become attractive drug targets.
Understanding the role of methionine oxidation in amyloid formation. Amyloid deposition is associated with many debilitating systemic and neurological diseases, including Alzheimer's disease. This project aims to understand the effect of protein oxidation on the process of amyloid fibril formation. This knowledge will assist in the discovery of the triggers of these disorders and may identify methods of combating them.
Imaging-based fluid-structure interaction modelling of carotid atherosclerotic plaque. This project aims to combine computational modelling, magnetic resonance imaging (MRI), mechanical measurement and pathological analysis to investigate carotid plaque progression, and quantify the critical blood flow and plaque stress/strain conditions under which plaque rupture is likely to occur. MRI-based 3D computational models with multi-component plaque structures and their interaction with blood flow wi ....Imaging-based fluid-structure interaction modelling of carotid atherosclerotic plaque. This project aims to combine computational modelling, magnetic resonance imaging (MRI), mechanical measurement and pathological analysis to investigate carotid plaque progression, and quantify the critical blood flow and plaque stress/strain conditions under which plaque rupture is likely to occur. MRI-based 3D computational models with multi-component plaque structures and their interaction with blood flow will be developed and solved numerically to identify suitable plaque rupture risk indicators. Mechanical properties of plaque components will be measured ex-vivo and fibre orientation-based constitutive rules will be developed. This project aims to lead to quantitative understandings of plaque progression and rupture.Read moreRead less
Dynamics of atherosclerotic plaque formation, growth and regression. This project aims to provide a mathematical framework to interpret plaque growth. Many biological processes contribute to the growth of atherosclerotic plaques inside arteries. Lipoproteins enter the artery walls and stimulate tissues to signal to cells which duly respond so that fatty streaks form and grow into dangerous plaques that cause heart attacks or stroke. These processes are often nonlinear and operate on widely varyi ....Dynamics of atherosclerotic plaque formation, growth and regression. This project aims to provide a mathematical framework to interpret plaque growth. Many biological processes contribute to the growth of atherosclerotic plaques inside arteries. Lipoproteins enter the artery walls and stimulate tissues to signal to cells which duly respond so that fatty streaks form and grow into dangerous plaques that cause heart attacks or stroke. These processes are often nonlinear and operate on widely varying time scales. The project plans to use systems of ordinary differential equations, partial differential equations with non-standard boundary conditions, and bifurcation theory to find how nonlinear processes shape plaque growth. The expected results may demonstrate the importance of bifurcations, dynamics and nonlinear systems in plaque growth and provide new models to interpret biological data.Read moreRead less
Mechanisms of initiation and remodelling of intracranial aneurysms: a synthesis of hemodynamics and molecular biomarkers. Rupture of brain aneurysms can lead to severe disability and death. This project proposes novel ways of assessing risk of rupture using sophisticated mathematical models of blood flow in aneurysms and biochemical substances released in the blood. This will enhance basic understanding of aneurysm formation and improve treatment and management.
Arterial stiffness: mechanistic role of interaction of cellular processes and the extracellular matrix. Arterial stiffness causes high blood pressure with age, so with more people living longer it is important to understand why arteries become stiff. This investigation uses genetically engineered mice to study how changes in nitric oxide in the cells of the artery wall can lead to changes in the wall material and so affect arterial stiffness.
Blood pressure control by neural activation: underlying mechanisms of electric field stimulation and photostimulation of genetically targeted neurones. This project aims to understand how nerve stimulation can be used to treat drug-resistant high blood pressure. The project will lead to new benchmarks for interfacing novel technology with the nervous system and to development and enhancement of commercial devices similar to a cardiac pacemaker for patients with limited treatment options and poor ....Blood pressure control by neural activation: underlying mechanisms of electric field stimulation and photostimulation of genetically targeted neurones.

Cellular mechanisms linking smoking and cardiovascular disease. Everyone develops fatty streaks in their arteries. Why some streaks remain benign, and others progress to clinically-relevant lesions is not completely understood. This project will assess novel cellular mechanisms involved in plaque development, to enable the more effective design of new therapeutic strategies to treat heart disease.
From genes to organ function: understanding how heterogeneity in tissue modulates cellular behaviour in the heart. New computational and software engineering approaches are developed to model the electrophysiological variability of the heart and the mechanisms inducing arrhythmias. A significant outcome is a set of practical tools vital to cardiac research that provide medical specialists the ability to test hypotheses on low-cost powerful computing hardware.
