Locomotion in virtual environments predicts cardiovascular responsiveness to subsequent stressful challenges

Maria del Carmen Sandi Perez, Nathalie Heidi Meyer, João Pedro de Matos Rodrigues, Stephan Streuber, Erik Hans Jakob Studer

Individuals differ in their physiological responsiveness to stressful challenges, and stress potentiates the development of many diseases. Heart rate variability (HRV), a measure of cardiac vagal break, is emerging as a strong index of physiological stress ...

LPA1 receptor and chronic stress: Effects on behaviour and the genes involved in the hippocampal excitatory/inhibitory balance

Maria del Carmen Sandi Perez, Olivia Zanoletti, Alexandre Claude Gustave Bacq, Roman Moreno Fernandez

The LPA1 receptor, one of the six characterized G protein-coupled receptors (LPA1–6) through which lysophosphatidic acid acts, is likely involved in promoting normal emotional behaviours. Current data suggest that the LPA-LPA1-receptor pathway may be invol ...

Metabolic signature in nucleus accumbens for anti-depressant-like effects of acetyl-L-carnitine

Rolf Gruetter, Maria del Carmen Sandi Perez, Jocelin Grosse, João Pedro de Matos Rodrigues, Antoine Timothée Cherix, Thomas Didier Larrieu

Emerging evidence suggests that hierarchical status provide vulnerability to develop stress-induced depression. Energy metabolic changes in the nucleus accumbens (NAc) were recently related to hierarchical status and vulnerability to develop depression-lik ...

On the definition of an effective stress for shales

Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo

Energy-related engineering applications involving shales pose ever-increasing challenges for the constitutive modelling of these geomaterials. The present work proposes a new definition of effective stress developed by using a thermodynamic approach associ ...

Neurobiological links between stress and anxiety

Maria del Carmen Sandi Perez

Stress and anxiety have intertwined behavioral and neural underpinnings. These commonalities are critical for understanding each state, as well as their mutual interactions. Grasping the mechanisms underlying this bidirectional relationship will have major ...

Anisotropic behaviour of shallow opalinus clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Alberto Minardi

Opalinus Clay shale, the selected host geomaterial of a high-level radioactive waste repository in Switzerland, was sourced at shallow depth in a borehole in the northern part of the country. Pairs of specimens, retrieved from the same depth were prepared ...

Low vagal tone in two rat models of psychopathology involving high or low corticosterone stress responses

Maria del Carmen Sandi Perez, Damien Sébastien Huzard, Jocelin Grosse, Sriparna Ghosal

The two stress-responsive physiological systems, autonomic nervous system (ANS) and hypothalamus-pituitary-adrenal (HPA) axis exert complementary and interrelated actions in the organism. Individuals that suffer stress-related psychopathologies frequently ...

Constitutive differences in glucocorticoid responsiveness are related to divergent spatial information processing abilities

Maria del Carmen Sandi Perez, Simone Astori, Eleni Vasilaki, Damien Sébastien Huzard

The stress response facilitates survival through adaptation and is intimately related to cognitive processes. The Morris water maze task probes spatial learning and memory in rodents and glucocorticoids (i.e. corticosterone (CORT) in rats) have been sugges ...

An Effective Stress Framework for Clayey Geomaterials Including a Chemical-Dependent Variable

Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo

Experimental evidence shows that the chemical composition of the liquid inside the pores and its variation over time can have significant implications on the mechanical and hydraulic behavior of clayey geomaterials. The magnitude of these implications depe ...

Long term programming of psychopathology-like behaviors in male rats by peripubertal stress depends on individual’s glucocorticoid responsiveness to stress

Maria del Carmen Sandi Perez, Sophie Elizabeth Walker

Experience of adversity early in life and dysregulation of hypothalamus–pituitary–adrenocortical (HPA) axis activity are risk factors often independently associated with the development of psychopathological disorders, including depression, PTSD and pathol ...

Peripubertal stress increases play fighting at adolescence and modulates nucleus accumbens CB1 receptor expression and mitochondrial function in the amygdala

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti

Play fighting is a highly rewarding behavior that helps individuals to develop social skills. Early-life stress has been shown to alter play fighting in rats and hamsters as well as to increase aggressive behaviors at adulthood. However, it is not known wh ...

Compressive Strength and Deformation Capacity of Concrete under Sustained Loading and Low Stress Rates

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

This paper investigates the behaviour of concrete failing under high stress levels and subjected to different types of loading. The aim of this investigation is to clarify the development of linear and nonlinear creep strains and how they relate to materia ...
