One new alkaloid, 3-((6-methylpyrazin-2-yl)methyl)-1H-indole (1) was obtained from the deep-sea actinomycete Serinicoccus profundi sp. nov., along with five known compounds (2-6). Their structures were determined on the basis of detailed analysis of the 1D and 2D NMR as well as MS data. The new indole alkaloid displayed weak antimicrobial activity against(More)
Epilepsy is a serious neurological disorder in human beings and the long-term pathological events remain largely obscure. We are interested in elucidating long-term brain injury that may occur in the temporal lobe epilepsy, and time-course of neuronal death was examined in a mouse pilocarpine model of chronic epilepsy by Fluoro-Jade C (FJC) dye that can(More)
Neurogenesis in the hippocampus is actively involved in neural circuit plasticity and learning function of mammals, but it may decrease dramatically with aging and aging-related neurodegenerative disorder Alzheimer's disease. Accumulating studies have indicated that Wnt/β-catenin signaling is critical in control of proliferation and differentiation fate of(More)
AIMS Stromal cell-derived factor 1 (SDF-1) is critical for neural progenitor cell (NPC) migration after ischemia for nerve repair, but how hypoxic induction of SDF-1 is regulated has not been fully addressed. Here, we examined the regulation of SDF-1 hypoxic induction by the transcription factors nuclear factor-κB (NF-κB) and hypoxic inducible factor 1α(More)
Altered microRNA-205 (miR-205) expression has been found in glioma tissue samples and cell lines; however, the clinical significance of this is unclear. The aim of this study was to confirm the miR-205 expression pattern in human glioma and to investigate its clinical relevance. Quantitative reverse-transcription polymerase chain reaction assays showed that(More)
Epilepsy is a serious neurological disorder with neuronal loss and spontaneous recurrent seizures, but the neurochemical basis remains largely unclear. We hypothesize that D-serine, a newly identified endogenous co-agonist of N-methyl-D-aspartate (NMDA) receptor, may trigger excitotoxicity and neuronal damage in epileptogenesis. By using a mouse pilocarpine(More)
OBJECTIVE With the help with functional magnetic resonance imaging (fMRI) technique, we aim to clarify whether the marginal division of the striatum (MrD) is involved in the working memory function of human brain for remembering numbers received through hearing. METHODS Thirteen healthy volunteers were instructed to undertake both a working memory task,(More)
Some antiepileptic drugs (AEDs) have been reported to aggravate generalized seizures. We have seen three children whose myoclonic seizures increased on starting treatment with Levetiracetam. In all seizures aggravation was temporally associated to the introduction of the drug. All became seizure-free on withdrawal of levetiracetam with a switch to an(More)
Based on reports published so far, organophosphorus (OP) compounds do remarkable harm to human health. In 1995 there was an outbreak of organophosphorus-ester induced delayed neuropathy (OPIDN) due to tri-ortho-cresyl phosphate (TOCP) poisoning in northern suburbs of Xi'an in China. The 74 affected patients were treated and followed up after definite(More)
