Kidney transplantation used to be an experimental risky procedure, but is now routinely performed by many countries worldwide.

The organ in the Great Auditorium in the Academy Building has been played at walk-in concerts and University celebrations since 1998.

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

How do leadership behaviour repertoires take shape in public organizations?

Charisma K. Lepcha (PI, Sikkim University), Pradyut Guha (co-PI, Sikkim University), Rajib Sutradhar (co-PI, Christ University Bangalore) and Erik de Maaker (Leiden University) have been awarded a two-year grant of USD 18.000 to conduct research on the impact of ‘green farming’ on the sensitive mountain…

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.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

Cardiovascular disease is the number one cause of death worldwide. The most important risk factor for developing this disease is high cholesterol levels in the blood.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

Scholars interested in European law attended a conference in Praag to present their research, exchange ideas and reconnect with colleagues and friends.As Vice-Secretary General of the ELU-S, Martijn van den Brink played a crucial role in organizing the conference.

Do recent developments in the European security architecture signal the end of multilateral cooperation, or the beginning of a new era with emerging forms of international security collaboration?

Public management scholars have long debated public and private sector differences. However, the generalizability of empirical results has been limited due to the shortage of cross-national studies.

This paper describes two synthetic lipid models designed to replace human stratum corneum (SC) in studies of the impact of volatile organic chemicals on the molecular organization of the skin barrier lipids.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

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.

What is a good data protection law? How does a good data protection law evolve? Is European data protection law a good one? And whether the European data protection applicable to China?

Organ transplantation is often subject to ethical, economic and political discussions. In the Honours Class Organ Transplantation, students take part in these discussions to get a better understanding of the many different views on transplantation.

In what way did Hellenistic legal institutions concerning secured credit influence Roman law?

Can we develop new enzymes and cell factories to upgrade current enzyme cocktails towards complete degradation of biomass?

Bacteria and fungi on organic dairy farms are significantly different from those on conventional farms. That was discovered by postdoc researcher Sofia Gomes and her supervisors Nadia Soudzilovskaia and Peter van Bodegom in collaboration with the Louis Bolk Institute and Naturalis Biodiversity Centre.…

In this article, Tom Buitelaar proposes a systematic framework for analyzing the impact of individual characteristics of peacekeeping leaders on the behaviour of field-level personnel in UN peacekeeping operations.

Zeger van der Wal, Professor by special appointment Ien Dales Chair at Leiden University, and Mehmet Akif Demircioglu, Assistant Professor ar the Lee Kuan Yen School of Public Policy, researched the effects of ethical culture and ethical leadership on realized innovation.

On October 19, the Center for Law and Digital Technologies of Leiden University (eLaw) organized the first annual Hans Franken lecture. The lecture;

A new therapy for the serious Graft-versus-Host disease

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.
