How nature nurtures: Amygdala activity decreases as the result of a one-hour walk in nature

Since living in cities is associated with an increased risk for mental disorders such as anxiety disorders, depression, and schizophrenia, it is essential to understand how exposure to urban and natural environments affects mental health and the brain. It has been shown that the amygdala is more activated during a stress task in urban compared …

Stress-induced protein disaggregation in the endoplasmic reticulum catalysed by BiP

Protein synthesis is supported by cellular machineries that ensure polypeptides fold to their native conformation, whilst eliminating misfolded, aggregation prone species. Protein aggregation underlies pathologies including neurodegeneration. Aggregates’ formation is antagonised by molecular chaperones, with cytoplasmic machinery resolving insoluble protein aggregates. However, it is unknown whether an analogous disaggregation system exists in the Endoplasmic Reticulum …

Psychological and biological resilience modulates the effects of stress on epigenetic aging

Our society is experiencing more stress than ever before, leading to both negative psychiatric and physical outcomes. Chronic stress is linked to negative long-term health consequences, raising the possibility that stress is related to accelerated aging. In this study, we examine whether resilience factors affect stress-associated biological age acceleration. Recently developed “epigenetic clocks” such as …

#Heat stress and PPE during #COVID-19: impact on healthcare workers’ performance, safety and well-being in NHS settings

Personal protective equipment (PPE) can potentiate heat stress, which may have a negative impact on the wearer's performance, safety and well-being. In view of this, a survey was distributed to healthcare workers (HCWs) required to wear PPE during the coronavirus disease 2019 pandemic in the UK to evaluate perceived levels of heat stress and its …

Urinary #Stress Hormones, #Hypertension, and Cardiovascular Events: The Multi-Ethnic Study of Atherosclerosis

Psychosocial stress is a key contributing factor to the pathogenesis of hypertension and cardiovascular disease. We examined the association of urinary stress hormone levels with incident hypertension and cardiovascular events. This prospective cohort study included 412 adults (age 48–87 years) free of hypertension from the Multi-Ethnic Study of Atherosclerosis with measurements of urinary stress hormones …
