By measuring proteins in tears, ophthalmologists can more easily diagnose dry eyes (Dry Eye Disease). Peter Raus, a Belgian ophthalmologist and PhD student at the Institute of Biology Leiden, developed a new method for protein determination in tear fluid. The technique is also promising for the early…

They can play a role in metabolic disorders and can break down tough plant fibers: β-glycosidases are enzymes that play many roles in nature. Fredj Ben Bdira changed these enzymes in order to enhance the production of clean energy and to improve the treatment of patients with metabolic diseases.

Pharmacologist Liesbeth de Lange has won the Lewis B. Sheiner Lecturer Award from the International Society of Pharmacometrics (ISoP). As Professor of Predictive Pharmacology she is working, among other things, on a mathematical model that can predict drug concentrations in the brain. On the occasion…

On 3 April, Professor Syed Faisal Ahmed from the Leiden University Medical Center (LUMC) will give his inaugural lecture ‘Strength in Numbers’. He will emphasise the benefit of registries to rare disease research.

In the Netherlands, 1.55 million people suffer from cardiovascular diseases. Yet, acute cardiovascular events, such as a heart attack or stroke, often occur unexpectedly. That is because many people do not know they are at risk for such an event. Immunological researcher Amanda Foks and her colleagues…

Leiden Professor of Translational Rheumatology Hans Ulrich Scherer has one foot in the clinic, where he helps patients, and the other in the lab, where he supervises researchers. He bridges these two worlds in his hunt for autoimmune rheumatic diseases.

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…

Every year, an NWO PhD in the Humanities grant is awarded to a prospective PhD candidate at the Faculty of Archaeology. This year, the grant went to Maia Casna, enabling her to study respiratory disease in the past. ‘My hypothesis is that the rapid formation of cities in the medieval Netherlands, must…

Due to the increasing resistance to certain antibiotics, the life-threatening condition sepsis is becoming harder to treat. For her PhD project, Leiden pharmacologist Feiyan Liu used mathematical modeling to find out how antibiotics can be used more effectively to cure sepsis.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

A combination of two potential drugs gives hope of a 'super blockage' of an over-active immune system, Leiden researchers report in Nature. The breakthrough came from the crystallisation of a membrane protein.

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

How do practice and theory reinforce one another in neuroscience? Professor Birte Forstmann’s inaugural lecture on 2 October will be about building interdisciplinary bridges between cognitive neuroscience and cognitive models. Her approach may lead to brain research with fewer side-effects for patie…
