Leiden chemists discovered a new mechanism which might explain how multiple sclerosis shifts to a more severe form. Their findings contribute to unravelling the mysterious course of the disease. They have published their findings in the journal Biochemistry.

Cognitive decline (amongst other problems with attention, concentration, memory) is a common symptom in patients with a variety of brain disorders and has been related to healthy ageing as well. People suffering from cognitive deficits are often significantly hampered in their day-to-day functioning…

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.

This thesis has described novel synthetic methods to produce a variety of (glyco)peptides and their application in the study of various immunological processes.

Predictors of work functioning in persons with multiple sclerosis

We aim to gain a better understanding of the natural disease progression of ALS in order to improve clinical trial design and analysis and to support drug discovery and clinical development of new drugs.

How do fats and enzymes in the brain contribute to multiple sclerosis? In his PhD research, Daan van der Vliet combined chemistry and neuroscience to gain new insights into how brain disorders develop.

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Latent variable modeling of students' solution strategies and performance

Multiple Sclerosis, Parkinson’s and Alzheimer’s disease are the most common neurodegenerative disorders. Unfortunately, no effective treatments are currently available to halt the progression of these neuroinflammatory diseases [1].

Leiden Early Drug Discovery & Development (LED3) is a multidisciplinary research network at Leiden University dedicated to advancing innovative approaches in early drug discovery and development. The initiative brings together 58 principal investigators from four institutes—the Institute of Biology…

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

Andrea Giolai defended his thesis on 3 May 2017.

Collecting as much information as possible about administering a new medicine to people can save a lot of money.

What are the often invisible cognitive consequences of multiple sclerosis? Maureen van Dam mapped these out during her doctoral research. 'People usually notice the physical symptoms, but the cognitive symptoms deserve at least as much attention.'

The overall aim of the project is to investigate interests and their development over time in a daily life context, with particular attention for the transition from late secondary to post secondary education, and from late post secondary education to early career.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

Drug development critically depends on preclinical models that mimic human physiology, yet traditional two-dimensional cultures and animal models often lack predictive power.

The National Multiple Sclerosis Foundation need your vote for the best employer. This Award is based on the research project MS@Work from psychologists of the Health, Medical and Neuropsychology unit in Leiden. Last chance for voting on Thursday 14 November.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

This thesis proposes multiple paths towards the development of a performance practice in Computer Music.

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

Researchers at the Faculty of Science work at the frontiers of knowledge every day, tackling today’s major societal challenges. Their work is recognised through grants, prizes and other awards. We highlight some of these achievements below.

From children’s inability to identify animals to a big protest at the opening of the academic year: below are some of our most popular articles of 2019.

How has interreligious encounter in Ogbómòsó created multiple religious belongings and identities among individuals and groups?

There was a brief disruption to several services; all services are now available again.

In the specialisation Clinical Neuropsychology, part of the Master in Psychology, you will focus on fostering clinical and scientific skills based on a solid theoretical background as well as practical training in neuropsychology and (clinical) neuropsychological research.

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

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…

This project investigates how inhabitants of Leiden with a migratory background experience the extent to which their language and cultural background is welcomed in Dutch society and how this affects their identity, sense of belonging, and general wellbeing.
