Intracellular movement of protein aggregates reveals heterogeneous inactivation and resuscitation dynamics in stressed populations of Escherichia coli KU Leuven
Inactivation of bacterial pathogens is of critical importance in fields ranging from antimicrobial therapy to food preservation. The efficacy of an antimicrobial treatment is often experimentally determined through viable plate counts that inherently provide a poor focus on the mechanisms and distribution of (sub)lethal injury and subsequent inactivation or resuscitation behavior of the stressed cells, which are increasingly important features ...
Relative contribution of multiple stressors on copepod density and diversity dynamics in the Belgian part of the North Sea Universiteit Gent
Spatio-temporal dynamics in the gene expression of the copepod Temora longicornis in response to environmental stressors Universiteit Gent
Due to their rapid responses to environmental variation, planktonic organisms are used as bio-indicators of ecosystem changes. With the need for better understanding the impact of a changing environment on zooplankton communities, zooplankton monitoring programs have been carried out in the marine environment globally since the early 20th century. Most zooplankton monitoring studies focus mainly on variability in biodiversity and biomass. ...
The Cascade of Stress: A Network Approach to Explore Differential Dynamics in Populations Varying in Risk for Psychosis KU Leuven
Stress plays a central role in the development and persistence of psychosis. Network analysis may help to reveal mechanisms at the level of the micro-dynamic effects between stress, other daily experiences and symptomatology. This is the first study to examine time-lagged networks of the relations between minor daily stress, momentary affect/thoughts, psychotic experiences, and other potentially relevant daily life contexts in individuals ...
Species interactions and chemical stress: combined effects of intraspecific and interspecific interactions and pyrene on Daphnia magna population dynamics Universiteit Gent
Influence of different thermo-mechanical cycling routes on recovery stresses of annealed NiTi wires KU Leuven
In this study, the influence of different thermo-mechanical cycling routes on recovery stresses of annealed NiTi wires has been investigated by using a dynamic mechanical analyzer. The as-received wire was annealed in Argon atmosphere in the temperature range of 350 to 900 C. Differential scanning calorimeter was used to study the martensite transformation. In route I, the sample is deformed to 2% pre-strain and recovery stress is measured after ...
The underfill-microbump interaction mechanism in 3D ICs: impact and mitigation of induced stresses KU Leuven
3D IC assembly processes are introducing new stress mechanisms not observed in 2D environments, which have significant effects on the performance of both BEOL and FEOL. This paper deals with the underfill-microbump interaction mechanism observed after 3D IC stacking and focuses on its scarcely explored impact on the FEOL. FEOL stress sensors and finite element models are employed to analyze the interaction mechanism development on manufactured ...
Different stresses, similar morphogenic responses: integrating a plethora of pathways Universiteit Antwerpen
Exposure of plants to mild chronic stress can cause induction of specific, stress-induced morphogenic responses (SIMRs). These responses are characterized by a blockage of cell division in the main meristematic tissues, an inhibition of elongation and a redirected outgrowth of lateral organs. Key elements in the ontogenesis of this phenotype appear to be stress-affected gradients of reactive oxygen species (ROS), antioxidants, auxin and ...
