The term allostasis, which is defined as stability through change, has been invoked repeatedly by developmental psychopathologists to describe long-lasting and in some cases permanent functional alterations in limbic-hypothalamic-pituitary-adrenal axis responding following recurrent and/or prolonged exposure to stress. Increasingly, allostatic load models have also been invoked to describe psyc...

Amygdala is widely known as a critical neural hub for modulating negative emotions such fear and anxiety. Recent studies have shown that the basolateral amygdala (BLA) has reciprocal innervation, which plays an important role in regulating social interaction associative memory. However, connectivity pattern functional of contralateral projecting BLA neurons stress-related anxiety are not fully ...

objective: this study was designed to evaluate the effectiveness of cognitive-behavioral stress management training with regard to glycemic control, psychological distress (depression, anxiety, and stress) and quality of life in patients with type 2 diabetes. methods: a total of 60 patients with type 2 diabetes (34 females and 26 males mean age 49.5±5.7 y) were included in this study. they were...

Introduction: Despite the prevalence of and negative health consequences associated with perceived loneliness in older adults, few studies have examined interactions among behavioral, psychosocial, and neural mechanisms. Research suggests that physical activity and improvements in perceived social support and stress are related to reductions in loneliness. Yet, the influence of brain structure ...

young children with history of maternal stress during pregnancy suffer from several neurological and psychological disorders in the childhood. the purpose of this study was to investigate the effect of maternal stress during pregnancy on the neural apoptosis in the newborns. pregnant wistar rats were divided into control and stress groups. stress was applied on the pregnant females from day 15 ...

the objective of this paper is to develop an artificial neural network (ann) model which can beused to predict temperature rise due to climate change in regional scale. in the present work data recorded overyears 1985-2008 have been used at training and testing steps for ann model. the multilayer perceptron(mlp) network architecture is used for this purpose. three applied optimization methods a...

Herein, we investigated the effects of passive heat stress on human somatosensory processing recorded by somatosensory-evoked potentials (SEPs). Fifteen healthy subjects received a median nerve stimulation at the left wrist under two thermal conditions: Heat Stress and normothermic Time Control. The latencies and amplitudes of P14, N20, P25, N35, P45, and N60 at C4' and P14, N18, P22, and N30 a...

OBJECTIVE To evaluate parenting stress following infants' cataract extraction surgery, and to determine if levels of stress differ between 2 treatments for unilateral congenital cataract in a randomized clinical trial. METHODS At surgery, an intraocular lens (IOL) was implanted or children were left aphakic, treated with contact lens (CL). Stress measures were administered 3 months after surg...
