This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

The aim of this thesis was to develop novel treatment strategies for different types of eye melanoma utilizing zebrafish models. We first establish orthotopic and ectopic xenograft models for uveal and conjunctival melanoma by engraftment of the immortalized cells derived from these tumors into zebrafish…

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

This comparative study investigates court politics in four kingdoms that succeeded the south Indian Vijayanagara empire during the sixteenth to eighteenth centuries: Ikkeri, Tanjavur, Madurai, and Ramnad. Building on a unique combination of unexplored Indian texts and Dutch archival records, this research…

For early modern Europeans, the past was a measure of most things, good and bad. For that reason it was also hotly contested, manipulated, and far too important to be left to historians alone.

On Wednesday 13 December 2017 Jaap Wieland defended his doctoral thesis entitled ‘De bescherming van concurrentiebelangen in het bestuursrecht’ (the Protection of Competition Interests in Administrative Law).

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

Would you like Leiden University to be a more open workplace that recognizes and rewards all contributions, and an institution that creates and shares knowledge more freely with society?

Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…
