BACKGROUND To investigate whether anxiety and depression levels are associated with Heat Shock Protein 70 (HSP70) induction in the colon of patients with ulcerative colitis (UC). METHODS The design was cross-sectional. Clinical activity was assessed by the Rachmilewitz Index (CAI). Three psychometric questionnaires were used: Zung Depression Rating Scale (ZDRS), Spielberg State-Trait Anxiety ...

The error-related negativity (ERN) is an event-related potential (ERP) that indexes error monitoring. Research suggests that the ERN is increased in internalizing disorders, such as depression and anxiety. Although studies indicate that the ERN is insensitive to state-related fluctuations in anxiety, few studies have carefully examined the effect of state-related changes in sadness on the ERN. ...

Previously, we have published that pharmacological induction of oxidative stress causes anxiety-like behavior in rats and also is associated with hypertension in these animals. Here, we report that sub-chronic induction of oxidative stress via pharmacological induction leads to i) reduction in glyoxalase (GLO)-1 and glutathione reductase (GSR)-1 expression; ii) calpain mediated reduction of bra...

This study examined how mood states affect nursing students' performance on a treatment procedure consisting of a novel combination of familiar clinical steps. Thirty third-year and fourth-year nursing students were first taught the procedure and then given both an anxious-mood and a calm-mood induction in a randomly assigned counterbalanced order. Anxiety was induced by showing a video of inte...

Oxidative stress (OS), which has been implicated in pathogenesis of many acute and chronic diseases, plays an important role in diverse neurological disorders including depression and anxiety. OS is caused by a large amount of reactive oxygen species or impaired enzymatic or non-enzymatic defense against it. OS has been suggested to contribute to etiology of mentioned disorders. This review int...

The present study examined whether trait anxiety and trait anger are associated with vulnerability to emotional eating, particularly among obese individuals. Lean (n = 37) and obese (n = 24) participants engaged in a laboratory study where they completed measures of trait anxiety and trait anger at screening and then completed 3 counterbalanced experimental sessions involving different mood ind...

OBJECTIVE Our aim was to observe if anxiety disorder patients - DSM-IV - respond in a similar way to the induction of panic attacks by a breath-holding challenge test. METHOD We randomly selected 29 panic disorder (PD) patients, 27 social anxiety disorder (SAD) patients, 21 generalized anxiety disorder (GAD) patients. They were induced to breath-hold for as long as possible four times with tw...

Cigarette smoking is associated with elevated risk of anxiety and mood disorder. Using the 7.5% carbon dioxide (CO2) inhalation model of anxiety induction, we examined the effects of smoking status and abstinence from smoking on anxiety responses. Physiological and subjective responses to CO2 and medical air were compared in smokers and non-smokers (Experiment One) and in overnight abstinent an...
