Microglia support the central and peripheral nervous system by forming the first line of defense against hazardous events. Microglia are increasingly acknowledged as critical players in neurodegenerative diseases, highlighting them as potential therapeutic targets.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

In het kader van de Honours Course ‘Crises in Biology’ die plaatsvond van 19 augustus t/m 2 september 2012 in Normandië, bezochten studenten vele geologische interessante locaties. Een van deze bijzondere plekken was de kust van Arromanches. Hier bemachtigden zij een enorm grote ammoniet die ze dinsdag…

Chemical-induced organ toxicity is a major concern in the development and use of chemicals, including drugs, pesticides, industrial chemicals and cosmetics. In the last decades, the onset and progression of chemical-induced organ toxicity has been linked amongst others to perturbation of mitochondri…

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…

Veel media besteden aandacht aan de gevolgen van pesticiden in de natuur. Onder andere in Trouw vertelt hoogleraar Martina Vijver dat niet alleen pesticiden die boeren gebruiken, maar ook schoonmaakmiddelen en muggenspray een groot effect op leven in het water. 'Als schadelijke stoffen in het water…

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

In eight chapters, the thesis of Rafaël Vos covers the effect of temperature and pressure on the electrochemical CO2 reduction.

Docenten spelen een cruciale rol bij het implementeren van onderwijsvernieuwingen. Uiteindelijk hangt het succes van de implementatie af van de manier waarop docenten de vernieuwing vormgeven in hun dagelijkse lespraktijk.

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

The research provides insight into disease behavior in both rural and semi-urban areas in Serengeti in Tanzania.

Nierfalen is een serieus probleem omdat nieren zichzelf niet kunnen regenereren na ernstige beschadiging. Een mogelijke oplossing bestaat uit het kunstmatig laten groeien van gezond nierweefsel. Daarvoor moeten wetenschappers eerst de ontwikkeling begrijpen tijdens de allereerste fase, in de foetus.…

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

Solute carrier (SLC) transporters are a large and diverse class of relatively understudied transmembrane proteins.

Op 12 november verdedigde Jip Stam het proefschrift 'Vrijheid van meningsuiting en de bestrijding van discriminatie in Nederland: een constitutioneel ontwikkelingsperspectief'. Het promotieonderzoek is begeleid door Afshin Ellian en Bastiaan Rijpkema.

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

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.
