Activity-based protein profiling (ABPP, also termed chemical proteomics), is one of the pillars of chemical biology, and at LED3 we have taken it to the next level. ABPP allows the assessment of protein function in live cells and tissues, which means that the activity of a complete protein family can…

This team will investigate how the bachelor can add more depth and reflection to the factual knowledge.

The close interaction between organic chemi stry and biology goes back to the late 18th century, when the modern natural sciences began to take shape. After synthetic organic chemistry arose as a discipline, organic chemists almost immediately began to pursue the synthesis of naturally occurring compounds,…

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

Describe and identify what dosimetry parameters are of importance to interpret dose-response relationships (eg., mortality, sub-lethal, growth or reproduction inhabitation, DNA damage and reactive oxygen species, etc. ) for metal-based nanoparticles? How to develop quantitative models that enable to…

Recently, the booklet 'Blended Learning, het versterken van het onderwijs op de Universiteit Leiden' has been launched. Sonja Wagenaar, educational adviser at ICLON, was project manager of the three-year Blended Learning Program in which blended learning training was implemented in the studies Psychology,…

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

This article on private active cyber defense by Dennis Broeders is part of a special issue of the Journal of Cybersecurity, based on a selection of contributions taken from the 2019 Conference on Cyber Norms organized by The Hague Program for Cyber Norms.

This thesis describes the design and development of subunit‐selective inhibitors of particular catalytically active subunits of human constitutive proteasomes and immunoproteasomes.

How do parliamentarians secure their political future? Are their activities in the legislature connected to their place on the candidate list from one election to the next? Political scientists Tom Louwerse and Cynthia van Vonno examine the Dutch case. Their main finding is that speaking in the plenary…

Active-site directed probes are powerful in studies of enzymatic function. We report an active-site directed probe based on a warhead so far considered unreactive.

In this article in International Affairs, Saskia Postema and Jan Melissen examine Chinese celebrities' UN-affiliated Weibo activism in the context of China's increasing engagement in the United Nations, which coincides with a shrinking domestic public sphere under Xi Jinping's leadership.

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

Cytotoxic T-cells (CTLs) are involved in the clearance of viruses and killing of tumor cells.

How was anti-communism organized in the West? New volume edited by Giles Scott-Smith, Luc van Dongen and Stephanie Roulin on the aims, arguments and associations of a range of transnational anti-communist activists during the Cold War.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

Glycosidases (GHs) are enzymes responsible for the degradation of carbohydrates and play many roles in human health and pathophysiology. Often, abnormal levels of glycosidase activity are markedly linked to human pathologies.

Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

The cannabinoid CB2 receptor (CB2R) represents a promising therapeutic target for various forms of tissue injury and inflammatory diseases. Although numerous compounds have been developed and widely used to target CB2R, their selectivity, molecular mode of action and pharmacokinetic properties have…

This article investigates the efforts of influential Turkish Muslim civil society actors to amplify the voices of Muslim women in the Netherlands.

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

Can we tailor catalysts at the atomic scale by means of high-school chemistry and geometry rules?

In the present-day United States, to what degree(s) are far-right men and women similar and/or dissimilar in their motivating factors for engaging in far-right social movement activism?

Quantifying physical activity (using accelerometers) and combining the frequency and intensity of activities with health data (brain MRI, traditional clinical parameters and metabolomics) is of utmost importance to monitor mobility and health among older individuals and study health promotion during…

The Learning and Behavior Problems in Education program group is responsible for teaching in the area of learning problems.

The aim of this study was to provide insight into how teachers in higher education can be supported in the design, implementation and evaluation of group assignments by developing a theoretical and evidence-based framework for the design of group assignments.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

In Dutch society’s discussions about remembering the colonial past, voice is often used as a metaphor for empowerment ('we must raise our voices'), whereas silence is often used as voice’s negative counterpart, signifying a loss or lack of power ('we will no longer be silenced'). Yet, silence is expressive:…

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

This book provides an overview of critical scholarly reflections on the history of Dutch slavery and colonization, as well as how this translates into critical cultural practices.
