Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applicati ....Numerical investigation of signal mechanotransduction of bone cells - application to bone remodeling. The understanding of signal mechanotransduction of bone cells is directly related to mechanical activation of bone remodeling processes, i.e., resorption and formation of bone tissue. Understanding of bone remodeling is essential for the development of new bone implants, the prognosis of osteosporosis, and studies related to changes in microgravity (e.g. space flight) to name a few key applications. This research proposal closely aligns with one of the major national research priorities, i.e., promoting and maintaining good health (ageing well, ageing productively). The research project is aimed to understand how mechanically induced loading may activate remodeling of bone.

Tissue engineering (TE) of heart valves is a new approach to cultivate a functional heart valve from human autologous cells. This innovative study aims to develop the technology to transplant cells onto a 3D biocompatible valve scaffold that is capable of mimicking native valve. The work proposed is a ground breaking study that will encompass development of a new biomaterial, manufacture of scaffolds using the Fused Deposition Modelling rapid prototyping process, hemodynamic optimisation and in vitro cell culture. This will advance our knowledge in cellular and scaffold technologies and may ultimately lead to the development of a TE heart valve.Read moreRead less
Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic ap ....Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic approach to simulataneuosly simulating the fluid dynamics, the valve motion and the stress in a synthetic Polyether urethane valve is proposed. Cell adhesion study will also be carried out. The findings may yield to new insights into valve research.Read moreRead less
Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and ....Rapid Development of Biocompatible Stent Grafts for Aortic Aneurysms. Weakening of the aorta may cause an aneurysm. The present technique of its treatment involves replacing the weakened portion of the aorta with a synthetic graft. Failure of this treatment often occurs due to non-compatibility of the stent graft with natural aorta. One possible reason for this is a mismatch between elastic natural aorta and the non-elastic artificial graft. The core component of our project is the selection and development of a suitable biomaterial and optimization of the stent design based on hemodynamics flow analysis and its fabrication with the Fused Deposition Modelling (FDM) process.Read moreRead less

Summary
Diamond cybernetics: nanocrystalline diamond for interfacing bionic devices with the human nervous system. Bionic devices will soon be used to treat disorders such as epilepsy, Parkinson's and depression. We will use diamond to create high resolution, permanent electrical connections between devices and the human nervous system. These diamond connections will preserve nerve health and make bionic devices more effective and able to last a lifetime.
In Vitro Study of Hemodynamic Stresses and Endothelialization of Artificial Coronary Arteries. Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces. This project aims to investigate the material for manufacturing the artificial a ....In Vitro Study of Hemodynamic Stresses and Endothelialization of Artificial Coronary Arteries. Restenosis (recurrence of the disease) is a major problem in the case of patients undergoing artificial artery by-pass surgery. Ideally the design for manufacturing the scaffold for cell adhesion of the artery should factor in hemodynamic forces and optimised geometry to withstand the hemodynamic stresses and other forces. This project aims to investigate the material for manufacturing the artificial artery using Fused Deposition Modeling and to develop methods for the establishment of endothelium on the artificial artery, concluding a restenosis-free solution for by-pass surgery. The knowledge gained through this work would be applicable to the design of other prosthetic devices.Read moreRead less

Cell replacement therapies offer potentially effective treatments for a host of neurological disorders but a major obstacle confronting their development is to ensure appropriate connections are formed within the brain. This proposal aims to utilize injectable biodegradable polymers, to demonstrate the feasibility of assisting neural cells and stem cells to bridge glial scars or significant distances in the brain and repair damaged neural pathways. This proposal will focus on naturally occurring polysaccharides, which will act as "scaffolds" for the growing neurones. The role the scaffolds play in regulating neurite extension will be investigated in vitro and in vivo.Read moreRead less
