We have developed a novel laboratory rodent model to detect competitive, non-competitive and no-hurdle foraging behaviors as seen in natural environment. However, it is not clear which brain region is important for the food foraging activity. In the present study, we evaluated the effect of lesions in the bilateral anterior cingulate cortex (ACC) on the rat(More)
Increased serotonin (5-hydroxytryptamine, 5-HT) release in the hippocampus induced by repeated stress is thought to be critical for the neuroadaptation that alleviates the adverse effects of stressors on emotion and behavior. A failure in this process may be one of the primary neuropathological mechanisms underlying the development of stress-related(More)
BRD7 is a bromodomain-containing protein (BCP), and recent evidence implicates the role of BCPs in the initiation and development of neurodevelopmental disorders. However, few studies have investigated the biological functions of BRD7 in the central nervous system. In our study, BRD7 was found to be widely expressed in various regions of the mouse brain,(More)
Psychological stress affects human health, and chronic stress leads to life-threatening diseases, such as depression and post-traumatic stress disorder. Psychological stress coping mechanisms involve the brain-derived neurotrophic factor (BDNF) and downstream cAMP response element binding protein (CREB), which are targets of the adverse effects of stress(More)
Prenatal stress can result in various behavior deficits in offspring. Here we tested the effects of environmental enrichment during gestation used as a preventive strategy on the behavior deficits of prenatal-stressed offspring rats as well as the underlying structure basis. We compared the effect size of environmental enrichment during gestation on(More)
In this study, a rat model of inflammatory pain was produced by injecting complete Freund's adjuvant into the hind paw, and the expression of acetylated histone 3 in the spinal cord dorsal horn was examined using immunohistochemical staining. One day following injection, there was a dramatic decrease in acetylated histone 3 expression in spinal cord dorsal(More)
MicroRNA (miR)-29a has been implicated in non-small cell lung cancer (NSCLC), but the mechanism remains largely unclear. LASP1, a cAMP- and cGMP-dependent signaling protein, was recently found to promote proliferation and aggressiveness in NSCLC. However, the regulatory mechanism of LASP1 expression in NSCLC, as well as the relationship between LASP1 and(More)
Melatonin has been shown to be involved in the processes that contribute to learning and memory. At present study, we tested the effects of exogenous melatonin (2.5 mg/kg) on contextual fear conditioning (experiment 1) and fear expression (experiment 2) in rats. Behavior procedure involved three training phases: habituation, fear conditioning and test.(More)
OBJECTIVE To observe the eff ect and mechanism of chronic high-fat diet on predation behavior in rats. METHODS Ten female SD rats with 4-week-old were randomly divided into a normal control group (NC group, n=5) and a chronic high-fat diet group (HF group, n=5). The rats in the NC group received the regular diet while rats in the HF group were fed with(More)
Emerging vehicular trajectory data have opened up opportunities to benefit many real-world applications, e.g., frequent trajectory based navigation systems, road planning, car pooling, etc. The similarity join is a key operation to enable such applications, which finds <italic>similar</italic> trajectory pairs from two large collections of trajectories.(More)
