A finite-element model of a two-dimensional slice of human atrial tissue for the study of the electrograms and propagation of action potentials is presented. Action potential propagation is described by a reaction-diffusion model coupled with the complex Courtemanche et al. atrial cell model. The effects of recording electrode size and location on electrograms are presented. Action potential propagation as a result of atrial fibrillation ablation therapy is also modeled by defining a lesion area with decreased electrical conductivity. The effect of electrical conductivity and geometry of the lesion was also studied. It is shown that the success rate of atrial fibrillation ablation therapy is primarily correlated with the creation of continuous ablation lines and also the formation of fibrous tissue.
Radio frequency ablation (RFA) has become the most commonly used ablative therapy for selected group of patients with liver tumors. To understand the effectiveness of RFA it is important to understand the mechanism of injury to the liver caused by RFA. There is no large animal model to study hepatocellular cancer. This book details the animal experiments carried out by the author in an attempt to create a porcine model of hepatocellular cancer. This book also details the discovery of Transition zone following ablation of liver tissue. This zone lies beyond the zone of cell necrosis and can not be identified by the usual histological techniques. Transition zone lies between necrotic liver tissue and normal liver parenchyma in lesion produced by RFA. This zone has cells showing apoptosis and increased expression of Heat Shock Protein (HSP) suggestive of cellular injury which will eventually lead to cell death. Further research to find techniques to increase the size of "Transition zone" may help in ablating larger areas of liver tumors.
Reconstruction of large and complex bone segments is one of the most challenging problems facing modern clinical practice. In order to diminish the donor site morbidity associated with autogenous bone transfer, synthetic biomaterials are being used nowadays to regenerate lost bone due to disease or trauma. The majority of currently applied regenerative medicine approaches rely on extrinsic vascularization, which could not be applied to reconstruction after cancer ablation. This book presents an experimental pilot study introducing for the first time the concept of axial vascularization of bone substitutes to regenerate mandibular defects in a large animal model (goat). The book is also presenting a review about conventional reconstructive techniques, describes the fine details of a novel model for axial vascularization and discusses its results in comparison with literature. The book contains valuable details suitable for graduate, and post-graduate researchers in the field of Reconstructive Maxillofacial surgery as well as biotechnology and Regenerative medicine.
