Creating information portals for support of European environmental policy.

OBJECTIVES: To determine whether the lipid/protein ratio and the total dry SC mass per surface area are related with the skin barrier function of controls and AE patients.

The barrier function of the skin is primarily provided by the stratum corneum (SC), the outermost layer of the skin. Skin barrier impairment is thought to be a primary factor in the pathogenesis of atopic eczema (AE).

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

In this study, we evaluated the influence of supercritical carbon dioxide (scCO2) spray drying conditions, in the absence of organic solvent, on the ability to produce dry protein/trehalose formulations at 1:10 and 1:4 (w/w) ratios.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

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.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

What is Leiden University doing to make its buildings future-proof and independent of fossil energy?

Leiden University's International Honours College, Leiden University College The Hague (LUC) experienced empty halls and empty classrooms this past year on the residential campus on the Anna van Buerenplein in The Hague due to the global pandemic. Dr Paul Hudson designed a Covid-proof course that enabled…

Would you like to do something for the victims of the war in Ukraine? Several actions have been set up to help the people in Ukraine. Read below what you can do.

If a society is to be secure, sustainable and resilient, conflicting interests must be reconciled. Researchers at Leiden University study the behaviour of individuals, groups and states in relation to this issue, and use their knowledge to promote equality within and between communities.

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Looking for ways to travel more sustainably once you've reached your destination? Here, we offer some ideas and helpful links to guide you in becoming a more responsible tourist. Ecotourism, defined as "responsible travel to natural areas that conserves the environment, sustains the well-being of…

Leiden University encourages all its laboratories to obtain LEAF (Laboratory Efficiency Assessment Framework) accreditation.

Description of 20th century changes in the Dutch flora: Description and interpretation (1999 - 2005)

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

How have human-environmental entanglements changed in the Gulf of San Miguel, Darien, Panama, from the first traces human practices through to the present?

The Institute of Public Administration studies the complex problems facing the public sector in the 21st century, from climate policy to the effects of digitalisation. Its researchers analyse, explain and help come up with solutions to the challenges of society today.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

How do you engage society to stop biodiversity loss? How do you create political and social involvement around climate change? And how do you balance the economic needs of the industry with the negative effects of pollution? If you find these kinds of questions interesting, then this Pre-University…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…
