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)
In the presence of a lateral periodic potential modulation, two-dimensional electrons may exhibit interesting phenomena, such as a graphene-like energy-momentum dispersion, Bloch oscillations, or the Hofstadter butterfly band structure. To create a sufficiently strong potential modulation using conventional semiconductor heterostructures, aggressive device(More)
Superoxide dismutase (SOD) has extensive clinical applications for protecting organisms from toxic oxidation. In this study, the integrated iron-superoxide dismutase gene (fe-sod) coding sequence of Nostoc commune stain CHEN was cloned from genomic DNA and compared to sods from other reported algae. These analyses of immunology and phylogenetics(More)
The slender, oval-shaped face is considered to be attractive in East Asia. To obtain the ideal contour of the midface, reduction malarplasty has been popularized in oriental countries in recent years. This report describes a surgical technique for reduction of the zygomatic body and arch. After labiobuccal vestibular incisions are made, the anterior(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)
Poly(ADP-ribose) polymerase (PARP) knockout mice are resistant to murine models of human diseases such as cerebral and myocardial ischemia, traumatic brain injury, diabetes, Parkinsonism, endotoxic shock and arthritis, implicating PARP in the pathogenesis of these diseases. Potent selective PARP inhibitors are therefore being evaluated as novel therapeutic(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)
