In our research protein translocation from Agrobacterium into yeast and plant cells is studied to obtain fundamental insights in the translocation process

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

Het onderzoek in dit proefschrift kijkt naar de rol van het locus ceuruleus - noradrenalinesysteem in verscheidene aspecten van menselijke cognitie, en de modulatie van de staat van het brein.

If mankind wants to survive into the 22nd century, we will need to change the way we live drastically. The human impact on our planet is everywhere, we are changing the atmosphere, the oceans and the land, leading to global warming, climate change, loss of biodiversity and pervasive pollution. There…

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Al het onderzoek van de Universiteit Leiden is georganiseerd in instituten. Om recht te doen aan de veelkleurigheid van het onderzoek (en dus ook aan het onderwijs) dat daar uit voortvloeit vindt u op deze pagina’s omschrijvingen van alle Leidse instituten.

Glycosidases are essential in fundamental biological processes and are responsible for the degradation of most (oligo)saccharides, glycolipids and glycoproteins.

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Childhood obesity is an increasing health issue. In the first part of this thesis comorbidities in children with obesity were studied, concerning the diagnostic process and dosing regimens.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Control of infectious diseases poses continuous challenges for human health.

Het onderzoek van de programmagroep Onderwijswetenschappen richt zich op ‘het lerende kind in het onderwijs’. De focus ligt op processen die plaatsvinden tijdens de ontwikkeling en het leren.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

In this course, you will develop an understanding of evolutionary processes and their formative power. You will see how evolution has shaped biodiversity, and continuously influences our daily life.

Deze minor richt zich op de cognitieve processen die invloed hebben op de wisselwerking tussen brein en bewustzijn.

This thesis focuses on addressing four research problems in designing embedded streaming systems.

The research programme Cities, Migration and Global Interdependence 1350-2000 (CMGI) focuses on urbanisation, migration, and economic development in a comparative and global context.

De chemische sector moet blijven vernieuwen voor een duurzamere en gezondere samenleving. De onderzoekers van het Leids Instituut voor Chemisch onderzoek (LIC) dragen daaraan met hun onderzoek en onderwijs bij door in te zetten op de thema’s duurzaamheid, energie en gezondheid.

A neurocognitive investigation of the development of social performance monitoring in youth growing up in stressful versus non-stressful environments

Hoe kan de methode om de gecombineerde effecten van metaal-gebaseerde chemische stoffetn te bepalen worden verbeterd?

BioSolar Cells is a five-year research project in which ten knowledge institutions and 45 private industries work together.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

In this thesis population pharmacokinetic and physiologically-based pharmacokinetic (PBPK) approaches were applied to investigate the influence of glomerular filtration (GF) and active tubular secretion (ATS) on renal clearance in children.
