Undergraduate emergency nursing students are often exposed to stress when helping patients in emergency situations. Emergency nursing students are vulnerable to the development of symptoms of post-traumatic stress Disorder (PTSD). Stress reactions among helpers can be regarded as a natural behavior and reaction when experiencing a traumatizing event and by the stress resulting from helping or w...

Piglets' individual behavioural traits have been studied in the last decade but no report has linked these traits with growth. This experiment was conducted to determine if behavioural traits of segregated early-weaned piglets could be good predictors of their post-weaning growth and, thus, help to predict their adaptation to early weaning. Following segregated early weaning at 17+/-1 days old,...

This study compared neuroendocrine and psychomotor responses in divers (D, n = 11) and non-divers (ND, n = 9) following 30-minute hyperbaric and decompression stress to 180, 300 and 450 kPa. Venous blood was drawn pre-dive and at 20 and 60 minutes post-dive and analyzed for norepinephrine (NE), epinephrine (E), tryptophan (TRP), cortisol (COR), growth hormone (GH), adrenocorticotrophic hormone ...

In contrast to the substantial number of studies investigating the effects of stress on declarative memory, effects of stress on working memory have received less attention. We compared working memory (numerical n-back task with single digits) in 40 men exposed either to psychosocial stress (Trier Social Stress Test (TSST)) or a control condition. Task difficulty was varied using two conditions...

stress is one of the effective factors in the development of depressive disorders that performs some parts of its effects by affecting hippocampus. since doxepin has been shown to have neuroprotective effects, in this study, we focused on the effects of doxepin on the expression of involved genes in neuronal survival and plasticity in the rat hippocampus following chronic stress. male wistar ra...

An imbalance between the formation of reactive oxygen species (ROS) and reaction antioxidant proteins is referred to as oxidative stress [...]

Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device de...
