Corticotropin-releasing factor (CRF), the stress-related neuropeptide, acts as a neurotransmitter in the brain norepinephrine nucleus, locus coeruleus (LC), to activate this system during stress. CRF shifts the mode of LC discharge from a phasic to a high tonic state that is thought to promote behavioral flexibility. To investigate this, the effects of CRF(More)
As an adverse early life experience, maternal separation (MS) induces profound neurochemical, cognitive and emotional dysfunction. Previous studies have reported that MS affected prepulse inhibition (PPI), anxiety-related behaviors, dopaminergic and serotonergic activity in adult rats, and in the present study, we investigated the effects of repeated(More)
Our previous research indicates that the extracellular signal-regulated kinase (ERK)-cyclic AMP-responsive-element-binding protein (CREB) signal system may be involved in the molecular mechanism of depression. The present study further investigated the effect of antidepressant fluoxetine on the ERK-CREB signal system and the depressive-like behaviors in(More)
In the present study, 40 Sprague-Dawley rats were divided into forced swim stress group and controls, with 20 rats in each group (10 for behavioral tests, 10 for protein detection). The forced swim stress group received swim stress for 14 consecutive days, and the controls were stress-free. After stress, 20 rats were tested for behavioral observation using(More)
Particular matter (PM) due to its side effects on human health like increase the risk of lung cancer and vision impairment has been one of the major concerns for air quality. These particles are now considered as one of the high priorities issues by health organizations in China. In this study, daily PM2.5 and PM10 concentrations data from November 2013 to(More)
Early postnatal maternal separation (MS) can play an important role in the development of psychopathologies during ontogeny. In the present study, we investigated the effects of repeated MS (4h per day from postnatal day (PND) 1 to 21) on locomotor activity and anxiety behavior in open field, spatial learning and reversal learning in Morris water maze of(More)
PURPOSE Effective communication among healthcare workers is critically important for patient safety and quality care. The purpose of this pilot study was to evaluate outcomes of a workshop designed to teach Chinese nursing students to use the Situation-Background-Assessment-Recommendation (SBAR) communication tool and examine their attitudes toward(More)
Immune responses can be modulated by Pavlovian conditioning techniques. In this study, to evaluate the conditionability of antibody response via a single-trial conditioning paradigm, we used a protein antigen ovalbumin as an unconditioned stimulus (UCS) that was paired with a novel taste of saccharin in a single-trial learning protocol. A significant(More)
Social isolation results in fundamental behavioral abnormalities in rodents which models certain neuropsychiatric disorders such as schizophrenia. However, the developmental stage that is most vulnerable to social isolation is largely unknown. In the present study, we subjected weaning rats to a four-week peri-adolescence isolation rearing (PAIR) and then(More)
Our recent research demonstrates that the extracellular signal-regulated kinase (ERK) signal pathway is impaired in depressed animals, and such disruption is effectively reversed following antidepressant treatment. These results indicate that the ERK pathway may participate in the molecular mechanism of depression. To provide direct evidence for the(More)
