Is het mogelijk om ziektes te diagnosticeren met behulp van moleculaire schakelaars? Over die vraag buigt het nieuwe internationale consortium LogicLab zich. Vanuit Leiden zijn scheikundige Sylvestre Bonnet en farmacoloog Thomas Hankemeier betrokken. Het project loopt voor vier jaar en krijgt ruim 3,5…

The ultimate aim of this project (initiated by the European Law Institute) is to design a framework that will enable the further development of coherent and functional rules for business rescue in Europe.

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Diacylglycerol lipases (DAGLα and DAGLβ) are responsible for the biosynthesis of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the brain and peripheral tissues. Selective DAGLβ inhibitors have been proposed as a potential treatment for inflammatory diseases with reduced potential for central…

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

The thesis is about how auxin and AGC kinases regulate male fertility. The main AGC kinases studied in this thesis is PDK1, PDK2 and AGC1.5, AGC1.7.

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.

Glucocorticoids are potent anti-inflammatory drugs widely used clinically to treat various inflammatory and immune conditions. However, two main clinical problems limit their use. GCs trigger severe side effects and they induce acquired glucocorticoid resistance, especially during chronic systemic treatment…

This thesis explores different avenues to develop insurmountable antagonists for CC Chemokine Receptors, such as CCR1, CCR2 and CCR5.

Planets are formed in disks of gas and dust around young stars.

Na het afronden van de bacheloropleiding volgen verreweg de meeste studenten de masteropleiding. De Universiteit Leiden stimuleert studenten om na hun bacheloropleiding door te gaan met de masteropleiding.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.

Kinase inhibitors are key therapeutic agents, particularly in oncology, yet their clinical efficacy is often hampered by off-target effects and limited understanding of their cellular target profiles.

Drug induced organ toxicity is the main problem of the drug development and drug usage in the clinic. The liver and kidneys are the most sensitive organs towards drug induced toxicity.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

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

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

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

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

The spindle-assembly checkpoint (SAC) is a safety mechanism which secures accurate chromosome segregation during mitosis.
