For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

De eerste index om de veiligheid, duurzaamheid en circulariteit van producten te meten, waarmee ze het EU-kader (SSbD) operationaliseren.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

We analyse the link between media consumption and the attitudes toward people living with HIV/AIDS in Chile. We used data from a sample of 1000 people, obtained in the 2011 wave of the World Values Survey (WVS). We use a logistic binary regression model by maximum likelihood. Our results suggest that…

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.
