BACKGROUND Chronic pain conditions are characterized by significant individual variability complicating the identification of pathophysiological markers. Leukocyte telomere length (TL), a measure of cellular aging, is associated with age-related disease onset, psychosocial stress, and health-related functional decline. Psychosocial stress has been associated with the onset of chronic pain and c...

BACKGROUND Stress is known to activate or exacerbate dermatoses, but the relationships between chronic stress, job-related stress and sickness absence among occupational hand eczema (OHE) patients are inadequately understood. AIMS To see whether chronic stress or burnout symptoms were associated with cumulative sickness absence in patients with OHE and to determine which factors predicted sic...

Acute stress modulates multiple memory systems in favor of caudate nucleus-dependent stimulus-response and at the expense of hippocampus-dependent spatial learning and memory. We examined in mice and humans whether chronic stress has similar consequences. Male C57BL/6J mice that had been repeatedly exposed to rats ("rat stress") used in a circular hole board task significantly more often a stim...

Introduction: The brain glutamate neurotransmitter system and its NMDA receptors in the nucleus accumbens play an important role in the incidence of the phenomena of sensitivity and addiction. The present study examined the inhibitory effect of glutamate NMDA receptors in the nucleus accumbens in response to chronic stress. Methods: After the unilateral and bilateral cannula placement in the ...

The present study examined whether chronic stress is related to daily life levels of salivary alpha-amylase (sAA), a marker for sympathetic activity, and cortisol in healthy children versus children with asthma. Children's sAA and cortisol levels were measured repeatedly over 2 days. Chronic stress measures included interviews with children about chronic home life stress and interviews with par...

Children’s sAA and cortisol levels were measured repeatedly over 2 days. Chronic stress measures included interviews with children about chronic home life stress and interviews with parents...

We examined the effects of acute and chronic stress on neurotransmission of nociceptin/orphanin FQ (N/OFQ) in a variety of brain regions. Four groups of rats were exposed to chronic variable stress, and/or a single acute stress before decapitation. Group 1 served as unstressed controls. The rats in group 2 (chronic stress/no acute stress) were exposed to a 10-day regimen of chronic stress (two ...
