Internationaal geadopteerde kinderen gebruiken niet meer medicijnen dan hun niet-geadopteerde leeftijdgenoten.

De Universiteit Leiden stimuleert studenten om na hun bacheloropleiding door te gaan met de masteropleiding. Je Leidse bachelordiploma Psychologie geeft je toegang tot de masteropleiding Psychologie in Leiden.

Een onderzoek naar hoe mensen eten en drinken tijdens hun dagelijkse routines, en onder welke omstandigheden dit plaatsvindt.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Nieuw onderzoek van de National University of Singapore en Leiden laat zien dat chimpansees en bonobo’s net zoveel contrast in hun ogen hebben als mensen, waardoor ze gemakkelijk de richting van iemands blik kunnen volgen.

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

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.

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…

Over the last decades, aviation safety has improved strongly. As a downside, airline pilots do not have as many opportunities to develop through experience the competencies that they need in critical situations.

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.

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

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…

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

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”.
