We have produced a draft sequence of the rice genome for the most widely cultivated subspecies in China, Oryza sativa L. ssp. indica, by whole-genome shotgun sequencing. The genome was 466 megabases in size, with an estimated 46,022 to 55,615 genes. Functional coverage in the assembled sequences was 92.0%. About 42.2% of the genome was in exact(More)
Growing evidence has implicated glial anomalies in the pathophysiology of major depression disorder (MDD). Gap junctional communication is a main determinant of astrocytic function. However, it is unclear whether gap junction dysfunction is involved in MDD development. This study investigates changes in the function of astrocyte gap junction occurring in(More)
AIM To investigate the effect and underlying mechanisms of polygalasaponin F (PGSF), a triterpenoid saponin isolated from Polygala japonica, on long-term potentiation (LTP) in hippocampus dentate gyrus (DG) of anesthetized rats. METHODS Population spike (PS) of hippocampal DG was recorded in anesthetized male Wistar rats. PGSF, the NMDAR inhibitor MK801(More)
Parkinson's disease (PD) is a chronic progressive neurodegenerative movement disorder characterized by the selective loss of nigrostriatal dopaminergic neurons. However, the molecular pathways leading to the dopaminergic neuron degeneration have remained obscure until recently. Reports demonstrated that reduction of brain-derived neurotrophic factor (BDNF)(More)

Gated solely by activity-induced changes in intracellular calcium, small-conductance potassium channels (SKs) are critical for a variety of functions in the CNS, from learning and memory to rhythmic activity and sleep. While there is a wealth of information on SK2 gating, kinetics, and Ca(2+) sensitivity, little is known regarding the regulation of SK2(More)
Epidemiological studies suggest an association between pesticides and the incidence of Parkinson's disease (PD). Individuals are likely to be exposed to numerous natural or synthetic environmental agents by ingestion, inhalation, or skin contact. Here, we describe a novel environment-contact administration of rotenone model, in which male C57BL/6 mice (15(More)
Parkinson’s disease (PD) is a common neurodegenerative disease, and its etiology remains obscure. Increasing evidence has suggested an important role for environmental factors such as exposure to pesticides in increasing the risk of developing PD and inflammation is the early incident during the process of PD. In this study, we measure the pro-inflammatory(More)
Angelman syndrome (AS) is a neurogenetic disorder caused by deficiency of maternally expressed ubiquitin-protein ligase E3A (UBE3A), an E3 ligase that targets specific proteins for proteasomal degradation. Although motor function impairment occurs in all patients with AS, very little research has been done to understand and treat it. The present study(More)
We perform an exhaustive, taxon by taxon, comparison of the branchings in the composition vector trees (CVTrees) inferred from 432 prokaryotic genomes available on 31 December 2006, with the bacteriologists' taxonomy--primarily the latest online Outline of the Bergey's Manual of Systematic Bacteriology. The CVTree phylogeny agrees very well with the(More)
