How does stress influence cognitive performance? What is the role of selective attention to threatening information in this effect? Could we prevent stress-induced decline of cognitive performance with pharmacological interventions? Could we use resting state theta/beta ratio as a biomarker for cognitive…

In this study, Bibi van den Berg and Sanneke Kuipers from ISGA, explore the ways in which cyber-related incidents may lead to crises

Polymyxins are clinically used antibiotics, discovered in mid-20th century. Once abandoned due to excessive nephrotoxicity, they are now used increasingly to address infections caused by multi-drug resistant Gram-negative bacteria.In this thesis, we describe the development and synthesis of analogues…

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

Thirty years ago, mutations in the BRCA1 gene were first linked to hereditary breast and ovarian cancer, establishing a genetic basis for cancer development.

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…

In this book, a new generation of scholars offers fresh perspectives on the history of the Dutch slave trade. Traditionally, Dutch research has focused on business practices, often overlooking the enslaved and the complexities of illegal trade and violence.

This book brings together a collection of emergent research that moves the debate on desistance beyond a general consideration of individual and social structural influences.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Currently the focus of the project is the development of a tool that utilizes dimensionality reduction techniques in order to analyze and interpret the lexical and phonological variation between different sign languages. Additionally, the application of deep learning techniques for the extraction of…

Symposium & Workshop

Massive science communication projects should be based on strong and relevant science cases. They should engage with a large number of stakeholders, not only in research, academia, policy, funding and governance but also in less traditional communities, such as the arts field. This is the outcome of…
