Deze serie benadert begrijpend lezen vanuit een cognitief perspectief. We beschrijven hoe lezers tot begrip komen. Dat wil zeggen: hoe zij coherente mentale representaties opbouwen tijdens het lezen van tekst.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

Lipid signaling is an essential biological event/process in a plethora of pathophysiological conditions. The underlying idea of this thesis is that many of the roles and the complex interplay of the individual signaling lipids in inflammatory processes and related conditions in health and disease is…

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…
