Second Virtual International Symposium on Cellular and Organismal Stress Responses, September 8-9, 2022

Paolo De Los Rios

The Second International Symposium on Cellular and Organismal Stress Responses took place virtually on September 8-9, 2022. This meeting was supported by the Cell Stress Society International (CSSI) and organized by Patricija Van OostenHawle and Andrew Tru ...

Transcriptomic analysis reveals mitochondrial pathways associated with distinct adolescent behavioral phenotypes and stress response

Maria del Carmen Sandi Perez, Dogukan Hazar Ülgen

Adolescent individuals exhibit great variability in cortical dynamics and behavioral outcomes. The developing adolescent brain is highly sensitive to social experiences and environmental insults, influencing how personality traits emerge. A distinct patter ...

Psychosomatic response to acute emotional stress in healthy students

Adriana Arza Valdes

The multidimensionality of the stress response has shown the complexity of this phenomenon and therefore the impossibility of finding a unique biomarker among the physiological variables related to stress. An experimental study was designed and performed t ...

A developmental shift in habituation to pain in human neonates

Sofia Charlotta Olhede

Habituation to recurrent non-threatening or unavoidable noxious stimuli is an important aspect of adaptation to pain. Neonates, especially if preterm, are exposed to repeated noxious procedures during their clinical care. They can mount strong behavioral, ...

Uncovering personalized glucose responses and circadian rhythms from multiple wearable biosensors with Bayesian dynamical modeling

Felix Naef, Nicholas Edward Phillips

Wearable biosensors and smartphone applications can measure physiological variables over multiple days in free-living conditions. We measure food and drink ingestion, glucose dynamics, physical activity, heart rate (HR), and heart rate variability (HRV) in ...

IMVEST, an immersive multimodal virtual environment stress test for humans that adjusts challenge to individual's performance

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

Laboratory stressors are essential tools to study the human stress response. However, despite considerable progress in the development of stress induction procedures in recent years, the field is still missing standardization and the methods employed frequ ...

Wearable and Continuous Prediction of Passage of Time Perception for Monitoring Mental Health

David Atienza Alonso, Lara Orlandic, Adriana Arza Valdes

A person’s passage of time perception (POTP) is strongly linked to their mental state and stress response, and can therefore provide an easily quantifiable means of continuous mental health monitoring. In this work, we develop a custom experiment and Machi ...

Genetic, metabolic, and molecular insights into the diverse outcomes of diet-induced obesity in mouse

Alexis Maximilien Bachmann

Overweight and obesity are increasingly common public health issues worldwide, leading to a wide range of diseases from metabolic syndrome to steatohepatitis and cardiovascular diseases. While the increase in the prevalence of obesity is partly attributabl ...

Long term effects of peripubertal stress on excitatory and inhibitory circuits in the prefrontal cortex of male and female mice

Maria del Carmen Sandi Perez

The impact of stressful events is especially important during early life, because certain cortical regions, especially the prefrontal cortex (PFC), are still developing. Consequently, aversive experiences that occur during the peripubertal period can cause ...

Metabolic and hemodynamic changes in the activated human brain and cerebellar organisation measured by MRS/MRl at 7 Tesla

Yohan Boillat

Although less often investigated than the positive blood-oxygen-level-dependent (BOLD) signal, a negative BOLD signal has also been observed under certain conditions, which could have a neuronal origin. To further investigate the negative BOLD signal from ...

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

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 ...

A numerical study on the coupled hydro-mechanical behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

Understanding the mechanical behaviour of compacted bentonite upon re-saturation is of outmost importance in most designs of nuclear waste disposal repositories. The behaviour of bentonite is characterized by its stress-path dependency and it is typically ...

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

Maria del Carmen Sandi Perez, Jocelin Grosse, Damien Sébastien Huzard, 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 ...

Probing the Global Cellular Responses to Lipotoxicity Caused by Saturated Fatty Acids

Manuele Piccolis

Excessive levels of saturated fatty acids are toxic to cells, although the basis for this lipotoxicity remains incompletely understood. Here, we analyzed the transcriptome, lipidome, and genetic interactions of human leukemia cells exposed to palmitate. Pa ...

Submaximal exercise testing at low altitude for prediction of exercise tolerance at high altitude

Johannes Burtscher

Annually, thousands of air travellers visit high altitude destinations to enjoy hiking tours to attractions in surrounding areas. However, many of them are not adequately trained, not sufficiently acclimatized and/or may suffer from pre-existing diseases. ...

Perceived interest and heart rate response to façade and daylight patterns in Virtual Reality

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo, Kynthia Chamilothori, João Pedro de Matos Rodrigues

This contribution introduces an experimental study aiming to provide concrete evidence on how façade and daylight pattern geometry can affect the emotional responses triggered by a space. The study was conducted in Virtual Reality (VR) where participants w ...

Impact of individual differences in glucocorticoid adaptation to stress on behavior, neurophysiology and metabolism

Damien Sébastien Huzard

The stress system is a key modulator of homeostasis and allows organisms to adapt to environmental changes. Proper survival is dependent on the appropriate stress response, for example initiating food (energy) intake or provoking physical reaction. However ...

High anxiety trait: A vulnerable phenotype for stress-induced depression

Maria del Carmen Sandi Perez, Meltem Weger

A great deal of research aims to identify risk factors related to individual vulnerability to develop stress-induced psychopathologies. Here, we summarize evidence that point at anxiety trait as a significant contributor to inter-individual differences in ...

Physiological Adaptations to Sugar Intake: New Paradigms from Drosophila melanogaster

Bruno Lemaitre, Wen Bin Chng

Sugars are important energy sources, but high sugar intake poses a metabolic challenge and leads to diseases. Drosophila melanogaster is a generalist fruit breeder that encounters high levels of dietary sugars in its natural habitat. Consequently, Drosophi ...

Cytosolic Proteostasis Networks of the Mitochondrial Stress Response

Johan Auwerx, Vincenzo Sorrentino, Davide D'Amico

Mitochondrial stress requires timely intervention to prevent mitochondria' and cellular dysfunction. Re-establishing the correct protein homeostasis is crucial for coping with mitochondria' stress and maintaining cellular homeostasis. The best-characterize ...
