Article Abstract
Stress might impair clinical performance in real life and in simulation-based education (SBE). Subjective or objective measures can be used to assess stress during SBE. This monocentric study aimed to evaluate the effects of simulation of life-threatening events on measurements of various stress parameters (psychological, biological, and electrophysiological parameters) in multidisciplinary teams (MDTs) during SBE. The effect of gender and status of participants on stress response was also investigated. Twelve emergency MDTs of 4 individuals were recruited for an immersive simulation session. Stress was assessed by: (1) self-reported stress; (2) Holter analysis, including heart rate and heart rate variability in the temporal and spectral domain (autonomic nervous system); (3) salivary cortisol (hypothalamic pituitary adrenal axis). Forty-eight participants (54.2% men, <7years of experience) were included. Measures were performed at baseline (T0), after simulation (T1), after debriefing (T2), and 30min after debriefing (T3). There was an increase in stress level at T1 (p<0.001) and a decrease at T2 (p<0.001). However, the variations of stress parameters induced by simulation (T0-T1 difference and T1-T2 difference) estimated by the three approaches were not correlated, while, as expected, Holter parameters were well-correlated to each other. Immersive SBE produced a change of stress level in all MDT members with no evidence for status effect but with gender difference. None developed a PTSD. These results support the hypothesis of a complementarity of the stress paths (collective reaction with increased stress level during simulation and a decrease during debriefing) but with relative independence of these paths (lack of correlation to each other). This study also suggests that because of the lack of correlation, stress response should be assessed by a combination of psychological, biological and electrophysiological parameters.

Burn injuries often cause prolonged oxidative stress and inflammatory pain due to an initial increase in inflammatory responses, consequently exacerbating depressive disorders and severely impairing patients' quality of life. The primary function of traditional burn dressings is to prevent infection and facilitate tissue repair. However, these dressings are not intended for the inflammatory pain and depression that often occur during recovery.

NAC [NO APICAL MERISTEM (NAM), ARABIDOPSIS TRANSCRIPTION ACTIVATOR FACTOR 1/2 (ATAF1/2), and CUP-SHAPED COTYLEDON (CUC2)] transcription factors are key regulators of plant growth, development, and stress responses but were also crucial players during land plant adaptation and crop domestication. Using representative members of green algae, bryophytes, lycophytes, gymnosperms, and angiosperms, we expanded the evolutionary history of NAC transcription factors to unveil the relationships among members of this gene family. We found a massive increase in the number of NAC transcription factors from green algae to lycophytes and an even larger increase in flowering plants.

Arbuscular mycorrhizal fungi may promote growth and stress resilience of plants, particularly under water-deficit conditions. However, interactions among mycorrhizal fungi, wheat plants, and aphids like the English grain aphid Sitobion avenae (Hemiptera: Aphididae) under water-deficit stress are still not well understood. Here, we examined the colonization of the fungus Claroideoglomus etunicatum (Glomerales: Claroideoglomeraceae) on wheat, and its effects on development and behavior of S.

Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of degradation. However, it remains unclear how critical tree physiological functions such as sap flow density (SFD) and tree water deficit (TWD, defined as reversible stem shrinkage when water is depleted), respond to extreme environmental conditions and how they interact under dry conditions. We monitored SFD and TWD of three co-occurring European tree species (Fagus sylvatica, Fraxinus excelsior and Acer pseudoplatanus) in dry conditions, using high temporal resolution sap flow, dendrometer, and environmental measurements.
