In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

De vakken die het VVI aanbiedt zijn onderdeel van het bredere onderwijsprogramma van de Faculteit der Rechtsgeleerdheid, dat programma’s aanbiedt op bachelor- (LLB) en masterniveau (LLM, Advanced Studies, PhD). Het instituut geeft een in Europa uniek MSc programma Law and Society: Governance and Global…

What are the pressing issues of our time, and how can different disciplines come together to address them? Studium Generale and Leiden University College (LUC) present the Global Challenges series: events that bring together researchers from LUC and experts from other disciplines to tackle a shared…

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

Azië en Europa hebben in toenemende mate met elkaar te maken. Om een duurzame samenwerking te bevorderen is het belangrijk elkaar op economisch, sociaal-cultureel, historisch, en juridisch gebied beter te begrijpen. Leidse wetenschappers leveren al decennia een belangrijke bijdrage aan de verwerving…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

In this thesis, single-cell approaches were applied to characterize the impact of aging on the immunological B cell landscape in different models of atherosclerotic cardiovascular disease, with the goal to identify and study new B cell-associated biomarkers and therapeutic targets to halt atherosclerosis…

In this thesis we study the moduli space of genus g curves, and the differential forms that occur naturally on this moduli space.

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…

Although plant domestication has significantly altered crop genetics and phenotypes, its effects on the taxonomic and functional diversity of plant-associated microbiomes are not well understood.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.
