Translational Neuroscience

Position of the course
In a report of the World Health Organization from 2006, neurological disorders contribute to 6.3% of the global burden of disease. This report estimates that the number of healthy life years lost because of neurological disorders will increase from 92 million in 2005 to 103 million in 2030, approximately a 12% increase mainly due to the aging population. Hence, there is still an important interest in neuroscience research to study the brain under normal and pathological conditions, even though, therapeutic successes have been few. Especially translational aims have been a remarkable
engine for driving research investment in the neurosciences. Translational
neuroscience is defined as:
1 Experimental non-human and non-clinical (basic science) studies conducted with the 1 specific intent to discover mechanisms, biomarkers, pathogenesis or treatments of
nervous system disorders.
2 Clinical studies that provide a foundation for developing, or that directly test, novel
therapeutic strategies for humans with nervous system disorders.
In other words, translational neuroscience will bring basic preclinical knowledge (from the bench) to clinical practice (to the bedside) to expand understanding of brain structure, function and disease, and translate this knowledge into clinical applications and novel therapies of nervous system disorders. Thus, translational neuroscience is the process of using all technological advances to bring novel therapies with measurable outcomes to patients with neurological diseases. In this course, emphasis will be on translational neuroimaging, where multiple imaging techniques are used to bridge the gap between preclinical research and clinic practice. These imaging
methods need to fulfil certain criteria such as being non-invasive (MRI), or at least minimal invasive (PET), and providing quantitative information to simplify the process of translating preclinical findings into the clinic.

Contrast Agents and Biomarkers for Imaging and Therapy

Position of the course
Contrast agents, also called imaging probes, radio-pharmaceuticals, tracers or dyes, are used in conjunction with medical imaging devices such as magnetic resonance imaging (MRI), computed tomography (CT), optical imaging, and nuclear imaging technologies like position emission tomography (PET) and single-photon emission computed tomography (SPECT). Contrast agents are used to provide the necessary signals to these image devices (SPECT, PET), or to improve signals to these imaging devices (CT, MRI).
Until recently, methods for diagnostic imaging provide predominantly anatomical information and/or functional information at a macroscopic level. The current diagnostic imaging revolution (=molecular imaging) change into a more disease-oriented one. In contrast to classical diagnostic imaging, molecular imaging sets forth to probe molecular and/or cellular abnormalities that are the basis of disease rather than to image the end results of these molecular alterations.
The importance of molecular targets, and probes aimed at these specific targets, for diagnosis and therapy has been recognized and different imaging procedures are introduced to visualize and quantify these molecular processes.

Biomedical Product Development

Position of the course
The aim of the course is to present students an overview of all steps required to solve a biomedical problem by designing a product prototype. Students will be taught how to apply a methodical way of designing a product, which should lead to enhanced product quality. By creating several possible solutions to a problem the chance to find the optimal solution is enlarged. All parts of the methodical design process will be practiced as group assignments (groups of 5 to 6 students). Since group work is very important part of product development, this will also be taught and practiced. In addition, lectures will be given on aspects of intellectual property rights (patenting), quality assessment and assurance, patient safety regulations, business development, green product developments. Lectures will also include presentations and testimonies from biomedical engineers in SME startup companies.

Designing biomedical products requires a specific methodical design process because of the diversity of the stakeholders, the different background of the project participants, the limitation of the amount of background information, and the complexity of the working environment. During this course tools are taught about:
• the methodical design process
• teamwork
• communication methods for a good cooperation between medical and technical
• experts
• application of selection processes
• project management
• intellectual property
• quality assurance, notified bodies
• basic financing
• business plan
