Autophagy is a fundamental degradative process, maintaining cellular homeostasis and functions in host defense against intracellular pathogens, including mycobacteria and Salmonella.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Sepsis is a life-threatening condition caused by a dysregulated host response to infection, it is associated with significant morbidity, mortality, and with a high financial burden on global healthcare systems. Bacterial infections are the primary cause of sepsis, but the growing prevalence of antimicrobial…

The filamentous bacteria Streptomyces are widespread inhabitants of terrestrial soils.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

The different kinds of cultural perspectives on health and disease of the participants are related to their knowledge, beliefs, values and practices manifested in various forms of lifestyle in Indonesia. The cultural diversity of the population is also related to differences in health behaviour.

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

Several single-stranded RNA viruses make use of Xrn1-resistant RNAs in their 3’ untranslated regions of their genome RNAs in order to increase their pathogenicity.

The Study Information Committee works to create a positive and accurate picture of the bachelor and master programs offered by the Institute of Biology Leiden (IBL). The committee consists of IBL staff members and study ambassadors. We reach out to future and current students, high school biology teachers,…

Het Europaeum is een netwerk van 17 vooraanstaande Europese universiteiten, met als doel om talentvolle studenten en docenten met elkaar in contract te brengen en door samenwerking en academische mobiliteit een 'Europees gevoel' te bevorderen.

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

This thesis investigates Open-world Continual Learning (OWCL), a learning paradigm designed for intelligent systems operating in non-stationary environments with persistent exposure to unknown data.

De rechtswetenschap is een verzamelnaam voor de 'juridica' en 'metajuridica'.

This thesis focuses on developing new chemical synthesis strategies to produce native ADP‑ribosylated biomolecules with precise structural control.

Quantum position verification (QPV) - the subject of this thesis - is a novel way to authenticate unknown nodes in a quantum network without the need to physically meet up.

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

Breast cancer (BC) is a clinically and biologically heterogeneous disease.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.
