Abstract:
Astrocytomas are the most common variety of primary tumours of the central nervous system (CNS). The incidence increases with age, peaking in patients aged 65--75 years. They are generally unresponsive to treatment, and most patients die within one year of diagnosis. Recent genetic studies of astrocytoma susceptibility syndromes, familial- and sporadic astrocytomas have led to the discovery of many genes and molecular mechanisms underlying astrocytoma oncogenesis. A few of the genes involved in inherited astrocytoma associated-syndromes (e.g., Cowden and Li-Fraumeni syndromes) are also strongl

Abstract:
The data presented in this thesis demonstrates that 60.0% of the morphologically normal samples from women at high risk for breast cancer showed genomic copy number aberrations by CGH. There was an average of 1.45 aberrations per sample analysed. These aberrations seemed to be spread throughout the genome, however, there were some regions of interest. These were gains on 1p, 9p, 16p 16q and 19. The presence of these aberrations suggests that morphologically normal epithelial cells analysed from these cases have a degree of genomic instability.

Abstract:
Malignant gliomas (MG), most notably glioblastoma multiforme (GBM), are among the most aggressive of all malignancies. High-grade variants of this type of brain cancer are generally considered incurable with singular or multimodal therapies. Many patients with GBM die within one year of diagnosis, and the 5-year survival rate in people is approximately 10%. Despite extensive research in diagnostic and therapeutic technologies, very few developments have emerged that significantly improve survival over the last seven decades. Irreversible electroporation (IRE) is a new non-thermal focal tissue

Abstract:
Glioblastoma multiforme (GBM) is the most common and lethal primary brain cancer with an average survival time of 15 months. GBM is considered incurable with even the most aggressive multimodal therapies and is characterized by near universal recurrence. Irreversible electroporation (IRE) is a cellular ablation method currently being investigated as a therapy for a variety of cancers. Application of IRE involves insertion of electrodes into tissue to deliver pulsed electric fields (PEFs), which destabilize the cell membrane past the point of recovery, thereby inducing cell death.
