The locus coeruleus noradrenergic (LC-NE) system is one of the first systems engaged following a stressful event. While numerous groups have demonstrated that LC-NE neurons are activated by many different stressors, the underlying neural circuitry and the role of this activity in generating stress-induced anxiety has not been elucidated. Using a combination of in vivo chemogenetics, optogenetic...
Background The sight of dental injection can bring about severe anxiety in children. Therefore, an alternative method that is convenient, effective, and keeps the needle hidden making it child friendly is necessary. The objective of the study was to compare the efficacy of a camouflaged syringe and conventional syringe on behavior and anxiety in 6-11-year-old children during local anesthesia ad...
This study provided an initial test of a theoretical model which emphasizes patterns of actual and perceived control. The model suggests that profiles of actual and perceived control are differentially related to emotional and behavioral problems. We examined whether anxiety and depression symptoms and aggressive behavior would differ among diverse patterns of actual (caregiver reported compete...
Testosterone (T) concentrations change rapidly in the context of human competition, and these changes in neuroendocrine function may serve to modulate future aggressive behavior. However, an increase in T during competition does not translate into aggressive behavior among all individuals. Here, we examined the extent to which individual differences in trait anxiety moderate the relationship be...
objective: acceptance-based behavior therapy (abbt) is a new psychotherapy for generalized anxiety disorder (gad). the current study intended to compare severity of symptoms, worry and quality of life of gad female patients between abbt and control. methods: this study was a randomized clinical trial. the sample included 18 women with gad referred to psychiatrists in isfahan, iran. patients wer...
Environmental uncertainty and uncontrollability cause psycho-physiological distress to organisms, often impeding normal functioning. A common response involves ritualization, that is, the limitation of behavioral expressions to predictable stereotypic and repetitive motor patterns. In humans, such behaviors are also symptomatic of psychopathologies like obsessive-compulsive disorder (OCD) and a...
objectives: major depression and anxiety disorders are common psychiatric disorders among cancer patients and are associated with psychosocial impairment and decreased quality of life. depressed and anxious cancer patients also experience a more rapid progression of cancer symptoms, increased mortality, more metastasis and pain, and increased medical utilization. although some research has expl...
BACKGROUND To investigate neurobiological correlates of trait anxiety, CD1 mice were selectively bred for extremes in anxiety-related behavior, with high (HAB) and low (LAB) anxiety-related behavior mice additionally differing in behavioral tests reflecting depression-like behavior. METHODOLOGY/ PRINCIPAL FINDINGS In this study, microarray analysis, in situ hybridization, quantitative real-ti...
