Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

This thesis focuses on addressing four research problems in designing embedded streaming systems.

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

Onze gemiddelde leeftijd gaat omhoog en de behoefte naar goede gezondheidszorg wordt steeds groter. Nieuwe medicijnen moeten op de markt komen maar kosten voor de ontwikkeling daarvan moeten omlaag. Tijdens het Medical Delta café op 8 oktober presenteren o.a. dr. Leo Price, dr. Jan de Sonneville en…

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Kijk hier de colleges terug die hoogleraar Design Timo de Rijk gaf in de week van 5 t/m 9 oktober bij de Universiteit van Nederland. In de colleges van De Rijk vind je antwoorden op vragen als: 'Hoe werd de Nederlandse huisvrouw bevrijd?' en 'Hoe stalen wij de fiets van de Britten?' Een must see!

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

Industrial manufacturing processes, such as the production of steel or the stamping of car body parts, are complex semi-batch processes with many process steps, machine parameters and quality indicators.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

Endothelial dysfunction and microvascular diseases are key drivers of cardiovascular disease, the world's leading cause of death.

Hoe meer we leren over een (neuro-)psychologische of lichamelijke aandoening en de hieraan gerelateerde gedragsfactoren, hoe beter we deze niet alleen kunnen signaleren, maar ook behandelen. Het is dus belangrijk dat recente inzichten over (neuro-)psychologische problemen en daaraan gerelateerde gedragsfactoren…

Als een nieuwe methode is ontwikkeld om een (neuro-)psychologische aandoening of hieraan gerelateerde gedragsfactoren te herkennen en te behandelen, kan deze nog niet direct in de klinische praktijk worden ingezet. Eerst moet de methode geëvalueerd worden, bij voorkeur in gerandomiseerde, gecontroleerde…

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

The prevalence of obesity (BMI >40 kg/m2) has increased rapidly over the recent years, not only in adults, but also in children and adolescents.
