In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

On Tuesday 14 February 2017 defended Kees van Gageldonk his doctoral thesis ‘Op zoek naar onderzoek. De totstandkoming van de onderzoekfunctie in het hoger beroepsonderwijs' at the Academy Building of Leiden University. Supervisor of the research is Prof.dr. W. Otterspeer with co-supervisor Dr. P.J.…

What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

The outermost layer of the skin, the stratum corneum (SC), is responsible for the skin barrier function, protecting the body from pathogens, chemicals and other unwanted substances from the external environment. The SC lipid matrix provides the only continuous pathway through the SC and is considered…

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

The skin protects the body from unwanted influences from the environment as well as excessive water loss. The barrier function of the skin is located in the stratum corneum (SC).

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

Psychologist Bernadet Klaassens initiated a large fMRI study on the effect of drugs on brain networks in aging and Alzheimer's disease. It generated a unique data set and insight into a new method to develop drugs for patients with Alzheimer's.

The Directorate-General Police, Sanctions, and Protection has initiated this research project in order to gain insight in the nature and, if possible, the extent of the developments with regards to the pluralization of policing functions in the Netherlands in support of future policies for the benefit…

This study explores regional variation in the use of utterance-final particles by analyzing spoken Taiwan Mandarin data recorded from spontaneous conversations.

Sorghum (Sorghum bicolor) is a major cereal crop that millions of subsistence farmers in Sub-Saharan Africa (SSA) rely on. However, the scourging impact of the root parasitic weed Striga (Striga hermonthica, a.k.a. “witch-weed”) has remained a major constraint hampering the productivity of sorghum in…

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

This study is the first to directly relate brain development to sex differences and school performance. The results debunk the myth that brain development is slower in boys.

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

An international partnership of brain researchers from 35 research centres - from the US to China - including the Leiden Institute for Brain and Cognition (LIBC), has collected resting-state functional MRI data from more than 1400 healthy volunteers and put the information online so that it is available…

An important feature of atopic eczema (AE) is a decreased skin barrier function. The stratum corneum (SC) lipids - comprised of ceramides (CERs), free fatty acids (FFAs) and cholesterol - fulfill a predominant role in the skin barrier function.

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).

In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.
