Identification and characterization of components of DNA repair pathways and their role in Agrobacterium T-DNA integration and repair of CRISPR/Cas induced DSBs.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

What is the most effective way to eliminate tumour cells? The DNA repair mechanism could play an important role in increasing the effectiveness of chemotherapy in the fight against cancerous cells. If we are to influence this mechanism, we need fundamental knowledge about how the mechanism works.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

In the studies described in this study, we introduce a novel ex vivo human skin barrier repair model. To develop this, we removed the upper layer of the skin, the stratum corneum (SC) by a reproducible cyanoacrylate stripping technique.

How does the extracellular matrix coordinate endothelial cell behavior during angiogenesis, and how do metabolic waste-products and matrix-degrading enzymes produced by the tumour modify the extracellular matrix so as the change the cellular coordination?

Atopic eczema is a skin disease with increasing incidence currently affecting 25% of the paediatric population. In atopic eczema the skin barrier function is reduced. This barrier is formed by the outermost layer of the skin called the stratum corneum (SC). The SC consists of terminally differentiated…

Searching for ways to delay the need for a transplant and trying to build kidneys to order.

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

In this article, the authors explore how international criminal law is moving into a ‘post-critical’ phase and examine its potential for emancipatory reform.

Why do some children confront social challenges with confidence, whereas others experience difficulties? What is the role of child temperament and child emotional dispositions? What is the role of parenting? This project aims to shed light on the mechanisms explaining shyness and confidence in response…

Are there any differences in gaze behavior between high and low socially anxious individuals? What factors influence the relation between social anxiety and gaze behavior?

A neurobiological perspective on individual differences in social competence

The studies outlined in this volume explore how connectedness continues to change Africa and how Africa continues to shape the social life of connections.

Do you have to be able to say everything on Twitter and Facebook? Is Instagram morally obliged to remove photos from attacks? Should we allow the terrorist group to recruit new members on the internet?

Social safety is all about creating a supportive community

At FGGA, we want our staff to feel safe in all respects. We therefore strive to create a work environment where we treat each other with respect, where we promote inclusion and where we speak up if we experience or witness unsafety.

There are several ways to stay up to date via social media.

An acute shortage of social care staff means that family members often quit their jobs to care for relatives with severe disabilities. This seems too good to be true – and there is a catch. Barend Barentsen, Professor of Labour law, discusses this on Dutch consumer programme ‘Radar’.

Social Science Matters is an online variant on London’s famous Speakers’ Corner – a platform for the researchers in the various disciplines in the Faculty of Social and Behavioural Sciences to react to the news. This soapbox gives our social scientists an opportunity to voice their opinions on current…

The [A]Social Creatures Lab is an interdisciplinary research lab that focuses on understanding social interaction with and between artificial creatures. Researchers and students from the Media Technology group collaborate in it.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

This interdisciplinary research project explores several adaptive machine learning methods which can give insight into the interaction between human and machine. The ultimate goal is open and natural communication between humans and AI that should result in mutual trust, cooperation and coordination…
