BACKGROUND AND PURPOSE Previously we demonstrated that the spinal sigma-1 receptor (Sig-1 R) plays an important role in pain transmission, although the exact mechanism is still unclear. It has been suggested that Sig-1 R agonists increase glutamate-induced calcium influx through N-methyl-D-aspartate (NMDA) receptors. Despite data suggesting a link between(More)
OBJECTIVES The paraoxonase (PON) gene can reduce the risk of developing atherosclerosis. We investigated the associations between PON polymorphisms and ischemic stroke. We also investigated the associations between PON polymorphisms and lipid profile in stroke patients. METHODS A total of 350 patients with ischemic stroke and 242 control subjects in(More)
We previously reported that a methanolic extract of Coptis japonica, which is a well-known traditional oriental medicine, inhibits morphine-induced conditioned place preference (CPP) in mice. Berberine is a major component of Coptis japonica extract, and it has been established that the adverse effects of morphine on the brain involve dopamine (DA)(More)
beta-Amyloid precursor protein binding protein 1 (APP-BP1) was previously identified based on its binding to the carboxyl terminal of beta-amyloid precursor protein. In this report, we have discovered that a mutation of dAPP-BP1 (Drosophila ortholog of APP-BP1) hinders tissue development, causes apoptosis in imaginal disc cells, and blocks the NEDD8(More)
Retinal neovascularization is the most common cause of blindness; Retinopathy of pre-maturity (ROP) for children and diabetic retinopathy for young age group. ROP still remains as the most serious cause of vision loss in children. We provided that deguelin significantly reduces retinal neovascularization in a mouse model of ROP. Deguelin never affected the(More)
In socially monogamous species, individuals can use extra-pair paternity and offspring sex allocation as adaptive strategies to ameliorate costs of genetic incompatibility with their partner. Previous studies on domesticated Gouldian finches (Erythrura gouldiae) demonstrated a genetic incompatibility between head colour morphs, the effects of which are more(More)
Although it has been known that activation of N-methyl-D-aspartate (NMDA) receptor effectively stimulates GnRH biosynthesis and release from the rat hypothalamus, no evidence that NMDA receptors exist in GnRH neurons is yet available. It is then presumed that the action of NMDA on GnRH neurons may be indirectly mediated through interneurons, such as(More)
