1. Algorithms for magnetic resonance imaging in radiotherapy
Abstract : Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more effective radiotherapy treatments with fewer side effects. READ MORE

2. A Co-Simulation Approach for Hydraulic Percussion Units
Abstract : This Licentiate of Engineering thesis concerns modelling and simulation of hydraulic percussion units. These units are often found in equipment for breaking or drilling in rock and concrete, and are also often driven by oil hydraulics, in which complex fluid-structure couplings are essential for their operation.

3. Robust Image Registration for Improved Clinical Efficiency : Using Local Structure Analysis and Model-Based Processing
Abstract : Medical imaging plays an increasingly important role in modern healthcare. In medical imaging, it is often relevant to relate different images to each other, something which can prove challenging, since there rarely exists a pre-defined mapping between the pixels in different images.

4. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines
Abstract : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. READ MORE

5. Inhibition of phagocyte signaling by the Yersinia virulence protein YopH
Abstract : Yersinia pseudotuberculosis evades the immediate immune defense of a host organism by inhibiting bactericidal functions of phagocytes, including phagocytosis, cytokine release, and the oxidative burst. Consequently, this pathogen can survive and multiply in lymphatic tissues. An ensemble of proteins called Yops are involved in the virulence of Y. READ MORE
