The emergence of complex diseases resulting from abnormal cell-cell signaling and the spread of infectious diseases caused by pathogens are significant threats to humanity. Unraveling the dynamic mechanisms underlying cell-cell signaling and infectious disease spreading is crucial for effective disease…

Nu het steeds beter lukt om de moleculaire gegevens van cellen en weefsels te ontsluiten, schept dat ook direct een nieuwe uitdaging. Want hoe vind je uit die enorme hoeveelheid data de juiste informatie voor onderzoek?

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

Model based approaches, integrating physiological parameters or linking exposure with response, are powerful tools to quantify and evaluate the impact of genetic differences that are reflected as variability of drug exposure and/or clinical response(s).

In this thesis, we will utilize embryonic zebrafish tumour models to understand the interaction between engrafted human cancer cells and macrophages from the host, test drug administration modalities and anti-cancer efficacies of newly-developed PDT and PACT compounds, and test a light-triggered liposomal…

We describe certain birational modifications of nodal relative curves over a regular base of arbitrary dimension.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

Dr. Irma Mosquera Valderrama onderzoekt in haar ERC-project de rol van de OESO (Organisatie voor Economische Samenwerking en Ontwikkeling) en de EU bij de totstandkoming van internationale fiscale wetgeving en streeft ernaar voorwaarden te scheppen waaronder zowel ontwikkelde landen als ontwikkelingslanden…

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Beginnend docenten hebben vaak moeite met het maken van activerende lessen. In dit onderzoek wordt gekeken hoe het didactisch bouwstenen model hen een helpende hand kan bieden bij het leren ontwerpen van lessen.

Uncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

This thesis focuses on important life history traits and their trade-offs using two hexapod models. Particularly, the trade-off between immune defense and embryonic developmental speed is a central theme of this study.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…
