In vitro disease models play a fundamental role in drug research. They enable the systemic identification and validation of disease mechanisms and the discovery of possible drug targets. However, more than often, drug candidates that are identified in vitro fail in the later clinical stages of drug…

Since its beginnings, Leiden University has been home to scholars with a broad and diverse expertise in the histories, languages, literatures and material cultures relevant to the study of Jews and Judaism from antiquity to modern times.

Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Read more

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Indicators to measure progress in de-linking economic growth and environmental pressure.

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

A substance flow analysis, covering about 99 % of the flows of chlorinated substances in the Netherlands.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

The present thesis focuses on the pharmacological concept of drug-target interaction, which dates back to the beginning of modern pharmacology.

Leiden University and the Ministry of Infrastructure and Water Management are involved in a collaboration in the form of a research project titled 'Data-Driven Risk Assessment in Infrastructure Networks'

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

The focus of the described research in this thesis is on the oxidative stress response (Nrf2 pathway). The aim of the research presented in this thesis is to obtain more information concerning microRNAs which are involved in the Nrf2 pathway, to determine and evaluate the application of microRNAs for…

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.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

An important part of the SCS specialisation is the internship period. Students will get the opportunity to get to know the field and to apply what they have learned during the courses.

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

To gain more insight into the evolutionary development of orchid flowers and fruits, the orchid species Erycina pusilla was studied. The evolutionary origin of the median petaloid sepal, the callus on the labellum, and the stelidia was studied.

Tuberculosis (TB) is associated with 1.5 million deaths annually. There is a need exists to optimize both current as well as novel antibiotic combination treatment strategies to improve the effectiveness and safety of treatments against TB.

Van 11 tot 17 september staat Leiden in het teken van kunst en wetenschap. Wat kan de combinatie van deze twee velden voor ons betekenen? En hoe kan de samenwerking ertussen worden versterkt? Verschillende publieksevents en een spiksplinternieuw symposium voor specialisten moeten antwoord geven op deze…

D2.2 comprises the in-depth legal analysis of the initial heuristic model, focused on addressing, in more detail, the main legal concerns for data reusers in the European data economy. This detailed analysis of the legal propositions presented in D2.1 is supplemented by an analysis of the technological,…

The class-imbalance problem is a challenging classification task and is frequently encountered in real-world applications. Various techniques have been developed to improve the imbalanced classification performance theoretically and practically.

This thesis is based on five papers on several topics.

An overview is given of the flows of chlorine and chlorinated hydrocarbons through the Europian Union.

Het Nederlands-Vlaams Instituut in Cairo (NVIC) is in 1971 opgericht. Negen universiteiten in Nederland en Vlaanderen participeren in het NVIC met als doel het stimuleren en internationaliseren van hun onderwijs- en onderzoeksactiviteiten in het Midden-Oosten. De beheervoerende instelling is de Universiteit…
