Empathic stress is the reproduction of psychological and physiological stress activation in an observer of a directly stressed target individual. It likely allows us to allocate the energy necessary to jointly alleviate a stressor at hand. The tendency to show such an empathic or "second-hand" stress response depends on the relationship between target and observer.

Microplastics have gained significant social attention, as they can enter our bodies through food and drinking water. The adrenal gland is essential for the maintenance of metabolic homeostasis and stress responses. Nevertheless, the effects of microplastics on the steroid synthesis in the adrenal cortex was still unclear.

Pig homeostasis is challenged by stressful production practices, like road transportation. Glucocorticoids (GCs) are mediators of reactive homeostasis, and their concentrations are frequently used as a stress indicator. The adrenocortical activity of fattening female and castrated male pigs was monitored over a 5-day longitudinal study.

The neurotrophic protein brain-derived neurotrophic factor (BDNF) plays a pivotal role in brain function and is affected by acute and chronic stress. We here investigate the patterns of BDNF and cortisol stress reactivity and recovery under the standardized stress protocol of the TSST and the effect of perceived chronic stress on the basal BDNF levels in healthy young men. Twenty-nine lean young men underwent the Trier Social Stress Test (TSST) and a resting condition.

Article Synopsis
- Chromosome 22q11.2 deletion syndrome (22q11.2DS) is linked to high rates of anxiety and psychosis, influenced by the COMT gene, which regulates important neurotransmitters.
- A study examined the relationship between COMT gene variations and anxiety as well as stress hormone responses in 30 affected children and adolescents.
- The findings revealed that those with the active COMTval allele experienced higher anxiety levels, while there was no significant difference in cortisol levels, indicating that COMT variations affect sympathetic stress responses more than hypothalamic ones.
