OBJECTIVES Previous research has found that chronic fatigue syndrome (CFS) patients report increased susceptibility to upper respiratory tract illnesses (URTIs) when compared with healthy volunteers. This study aimed to replicate and extend this research by investigating the role of psychological distress (stress and negative mood) in the recurrence of URTIs in CFS patients as well as its role ...

OBJECTIVE Chronic stress has well-documented negative effects on hippocampal structure and function, and has been suggested to contribute to age-related declines. In contrast, there is evidence that exercise has beneficial effects in older adults. The current investigation examined effects of lifetime stress on hippocampal volume and memory, the moderating role of stress on age effects, and the...

BACKGROUND Psychological stress and negative mood have been related to increased vulnerability to influenza-like illness (ILI). This prospective study re-evaluated the predictive value of perceived stress for self-reported ILI. We additionally explored the role of the negative affectivity and social inhibition traits. METHODS In this study, 5,404 respondents from the general population were a...

ackground: Stress, one of the strongest risk factors for depression, has been linked to “anhedonic” behavior and dysfunctional eward-related neural circuitry in preclinical models. ethods: To test if acute stress reduces reward responsiveness (i.e., the ability to modulate behavior as a function of past reward), a ignal-detection task coupled with a differential reinforcement schedule was utili...

BACKGROUND The prognoses of patients with false-negative test results by myocardial single photon emission computed tomography (SPECT) and by stress echocardiography are known to be different; the prognosis with false-negative SPECT is better in suspected and proven coronary artery disease (CAD). METHODS AND RESULTS Three strategies by which to diagnose CAD were compared for their cost-effect...

in order to study of sodium nitroprusside(snp) application effect on growth indices and water use efficiency of kidney beans cultivars(akhtar and derakhshan) under water deficit stress, an experiment was conducted in split factorial based in randomized complete block design with three replications in bu-ali sina university research field at 2012. water stress treatments included vegetative stre...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...
