On the 12th of November, Xander Vertegaal successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Xander on this achievement!

Combined hormonal contraceptives (CHC) are associated with an increased risk of venous thromboembolism (VTE). In 2013, a review was published by the European Medicines Agency (EMA). In this review, the authors concluded that the risk of VTE varies by the type of progesterone in the CHC. Subsequently,…

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.…

On the 12th of December, Eleanor Dutton successfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Eleanor on this achievement.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

This thesis attempts to establish a dialogue between the modern and the medieval traditions in logic, by means of ‘translations’ of the medieval logical theories into the modern framework of symbolic logic, i.e. formalizations.

This research cluster explores processes of cultural creation, reception and transformation within a wide range of societal contexts from the early Middle Ages until c. 1800.

Quincy Promes has been arrested in Dubai at the request of the Netherlands Public Prosecution Service. The Dutch judicial authorities now want Dubai to extradite Promes. But how does that work? Professor Jannemieke Ouwerkerk explains on ‘RTL Nieuws’.

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

Can zebrafish provide a fast, sensitive in vivo vertebrate model for identifying novel mechanisms of Ewing sarcoma progression and for development of new anticancer compounds in a time- and cost-effective manner?

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

We aim to develop a microfluidic platform that can parallelize testing the performance and characteristics of pure, mixed and environmental bacteriophage samples.

Markus Davidsen defended his thesis on 16 October 2014

This thesis describes the synthesis and biological evaluation of TLR2/6, TLR4, TLR7/8 and TLR9 ligands, of which the activity can be conditionally controlled.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Professor of Contemporary History Wim van den Doel has won the 2024 Boerhaave Biography Prize. Van den Doel receives the prize for his book 'Snouck: Het volkomen geleerdenleven van Christiaan Snouck Hurgronje'.

What is a university without its students? In 2025, we will celebrate 450 years of studying with an exhibition that puts our students from the past centuries in the spotlight. How did they study in the past? And how do they study now? The outdoor exhibition will be on display from 23 April at the Hortus…

The making of sacrifices seems part and parcel of any elite sportsperson’s life. Remarkably, the insights that we find in the current literature in social sport studies are not able to make sense of the references to sacrifice in the data that emerged in the context of this study on the social significance…

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

The aim of this study is to further develop the Open Science Monitor, which started as a pilot study.

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…

Can we predict fluctuations in suicidal ideation in a person’s daily life, from hour to hour?

The ARTIVES project studies imaginaries of diversity portrayed by artists in Lisbon and Rotterdam in their films, performances and (oral) literature with the aim to explore their transgressive potential of opening up possibilities of thinking differently about migration-related diversity. Their stories…

The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

In this article, Lianne Visser contributed to the understanding of why collaborative governance is a challenging response to wicked problems.
