BACKGROUND More than 500,000 hospitalized patients survive severe sepsis annually in the USA. Recent epidemiological evidence, however, demonstrated that these survivors have significant morbidity and mortality, with 3-year fatality rates higher than 70%. To investigate the mechanisms underlying persistent functional impairment in sepsis survivors, here we(More)
Hippocampal theta rhythm (4-12 Hz) can be observed during locomotor behavior, but findings on the relationship between locomotion speed and theta frequency are inconsistent if not contradictory. The inconsistency may be because of the difficulties that previous analyses and protocols have had excluding the effects of behavior training. We recorded the first(More)
The nuclear enzyme poly(ADP-ribose) polymerase (PARP), which has been shown to be activated following experimental traumatic brain injury (TBI), binds to DNA strand breaks and utilizes nicotinamide adenine dinucleotide (NAD) as a substrate. Since consumption of NAD may be deleterious to recovery in the setting of CNS injury, we examined the effect of a(More)
Hippocampal theta wave can be induced by running and is linked to cognitive functions. The initiation and maintenance of hippocampal theta during a complete course of running, however, is not well understood. Using a treadmill exercise model, this study wirelessly recorded the hippocampal electroencephalogram, nuchal electromyogram, electrocardiogram, and(More)
Legg-Calvé-Perthes disease (LCPD) is a significant problem in healthcare because it so commonly affects young adults and immature athletes, primarily gymnasts. In this paper, a two-degree-of-freedom (2-DOF) hip exoskeleton device was developed for study on an immature animal model of exercise-induced LCPD. The exoskeleton device can reproduce the repetitive(More)
The drinking behavior and the c-fos expression in rat brain induced by electrical stimulation of the subfornical organ (SFO) were examined. SFO stimulation induced stable and significant drinking behavior and Fos protein expression in 8 areas of the forebrain (organum vasculosum of the lamina terminalis, median preoptic nucleus, paraventricular nucleus,(More)
Relationship between pituitary gland and hypothalamic arcuate nucleus (ARC) in the modulation of pain threshold was investigated in Wistar rats with method of focal lesion and stimulation of pituitary gland. Experimental results indicated that electrolytic lesion of the pituitary intermediate and anterior lobes resulted in a decrease of pain threshold and(More)
In the present investigation, it was found that the number of beta-endorphin (beta-END)-immunoreactive neurons of hypothalamic arcuate nucleus (ARC) in MSG-treated rats decreased by 60.7%. No significant differences in the baseline pain threshold and the baseline corticosterone (CS) level were observed between the MSG-treated group and the control group.(More)
