Only 5% of all cases of intussusceptions occur in adults. Intussusception complicating colonoscopy is an extremely rare event. Herein, we present a case of a 58-year-old man who developed ileocolic intussusception after a colonoscopy during which an adenomatous polyp was discovered in the terminal ileum. Eight hours after colonoscopy, the patient developed(More)
Over the past years mathematical models, based on experimental data from MRI and CT scans, have been well developed to simulate the growth of aggressive forms of malignant brain tumours. The tumour growth model we are considering here, apart from proliferation and diffusion, is being characterized by a discontinuous diffusion coefficient to incorporate the(More)
The control of the outgrowth of neuronal cultured cells is of critical importance in a wide spectrum of neuroscience applications including tissue engineering scaffolds and neural electrodes. However, the study of neuron cell outgrowth on more complex topographies remains limited. Phenotype alteration of stem cells and differentiated neuronal cells cultured(More)
In this study we develop high order numerical methods to capture the spatiotemporal dynamics of a generalized Kolmogorov-Petrovskii-Piskunov (KPP) equation characterized by density dependent non-linear diffusion. Towards this direction we consider third order Strong Stability Preserving Runge-Kutta (SSPRK) temporal discretization schemes coupled with the(More)
