How can we manipulate the biotic and abiotic environment to increase thrips resistance in tomato and chrysanthemum? More specifically we ask: How can plant secondary metabolites that are not soluble in water be delivered to plants in seed coating or root dipping treatment? Can bacteria be used to…

Does a universal psychoeducational course about stress in adolescents: I) lead to an increase in knowledge of stress?, II) affect the frequency with which stressors are experienced and the overall stress level?, III) create interest in a tier 2 level follow-up training?, and IV) appeal to students in…

The major aim is to determine the role of stress and stress-related psychophysiological mechanisms (e.g., cognitions, behaviors, and physiological stress responses) of patients with chronic inflammatory conditions and to develop and evaluate stress management interventions to alter the psychophysiological…

Being a student can be stressful. Study pressure, living on your own, moving country, financial stress: things can be difficult. Unexpected difficulties may lead to study delay.

All living creatures have to cope with environmental demands and threats that challenge their physical or emotional homeostasis.

With this thesis the PhD-candidate aims to enrich the body of evidence concerning the relation between stress and health, and the mediating role of (un)conscious perseverative cognitions, which is captured in the extended perseverative cognition hypothesis.

How does the endocannabinoid system in the zebrafish function at the molecular and phenotypic levels and how is it linked to the stress axis?

What is the effectiveness of two school-based skills-training programs in promoting mental health?

Although exposure therapy is the gold-standard treatment of posttraumatic stress-disorder (PTSD), only half of the patients adequately benefit from it. Based on recent insights into the mechanisms of extinction, this project examines strategies and techniques to improve exposure treatment outcome in…

Can epigenetic changes explain associations between early life stress and health outcomes?

How can we facilitate the early recognition of stress and anxiety in the classroom and collaborate with schools in providing low-threshold interventions?

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

To what extent is sound a stressor to fish? And are behavioural and physiological phenotypes equally sensitive to disturbance by noise pollution?

Which microorganisms live near and inside plant roots? How do they contribute to plant health? Can microorganisms be employed in plant protection?

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

What is the role of neuronal emotional reactivity in the intergenerational transmission of abuse?

Cellular stress response pathways are activated upon exposure to chemicals and help organisms deal with various molecular dangers (e.g. oxidative stress). When these pathways become hyper-activated an adverse response takes place and cells die, which may lead to organism-level toxicity such as drug-induced…

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

Our vision of stress is starting to change fundamentally. We can suffer stress without even being aware of it, while sleeping as wall as during the day. Professor of Psychology Jos Brosschot will discuss this phenomenon in his inaugural lecture on 2 December.

Which compounds and microorganisms that live near and inside plant roots are beneficial? Can we use this knowledge to improve the health and growth of crop plants?

The central question of this Vici proposal is to investigate if, and how actinobacteria exploit life without a cell wall.

Stress, burnout, depression – these conditions pervade all levels of our society. Children and students suffer from constant pressure to achieve; at the international level, tensions lead to short-sighted actions; and, at the personal level, stress affects our health and social environment. How do our…

How can we quantify the density of species within a community through environmental DNA concentrations?

How does stress affect different components of behavioral impulsivity and aggression in patients with Borderline Personality Disorder compared to clinical controls (patients with Attention Deficit Hyperactivity Disorder) and healthy controls?

Salicylic acid (SA) is a plant hormone, which is involved in the defense responses to pathogens and to abiotic stress, and in the regulation of plant growth and development.

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…

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,…
