The loss of T-cell homeostasis and tolerance towards self-antigens is the underlying cause of autoimmune and inflammatory diseases like atherosclerosis, rheumatoid arthritis or type I diabetes. Traditionally, the treatment of these diseases consisted on systemic immune suppression, which can entail…

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

This thesis describes the use of a combined approach of computational and experimental techniques to gain novel insights to understand the glycosylation reaction and its reactive intermediates.

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

The recognition that there may be more, so-called allosteric binding sites on a given receptor has also fueled our synthetic efforts. Over the last few years we have focused on many drug targets (adenosine A1, A2A and A3 receptors, the mGlu2 receptor and a classic ‘anti-target’, the hERG channel) to…

Ceramides (CERs), cholesterol, and free fatty acids (FFAs) are the main lipid classes in human stratum corneum (SC, outermost skin layer), but no studies report on the detailed analysis of these classes in a single platform.

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

Although it is often assumed that the stereochemistry in Ugi multicomponent reactions is determined in the final Mumm rearrangement step, experimental and computational evidence that Ugi reactions on hydroxylated pyrrolines proceed under kinetic control is reported.

Description of Biotic ligand models: making an inventory of available models & assessment of the variability of the predicted HC5 using the BLMs in different Dutch water types (2005 - 2007)

How to make a quantitative assessment of the relative contribution to toxicity of ions and particles? Is the toxicity of nanoparticles related to their size or shape? Which physicochemical property of nanoparticles is an appropriate dose metric of nanoparticles?

Can a proposed new radiofrequency approach to graphene biosensors lead to groundbreaking changes in genome mapping?

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

Dr. Foks obtained this fellowship for the project “Can promotion of efferocytosis induce regression of atherosclerosis?”, in which she aims to identify novel targets to promote regression of atherosclerosis. This research grant allows her to initiate independent research for the next three years.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…
