The role of voltage-dependent potassium channel currents in glutamate-treated rat hippocampal neurons was investigated. Cell viability was evaluated by MTT reduction assay and morphological changes. Apoptosis was detected by Hoechst33342 staining with fluorescent microscopy and propidium iodide staining with flow cytometry. Membrane potassium channel(More)
An efficient in vitro mutagenesis protocol for Lilium longiflorum Thunb. cv. White fox has been established. The effect of 6-BA and NAA on adventitious bud formation from the bulblet-scale thin cell layers was tested. Results showed that the optimal medium for adventitious bud induction is MS basal medium supplemented with 2.0 mg/l 6-BA and 0.1 mg/l NAA.(More)
The true programmed mechanisms of delayed neuronal death induced by global cerebral ischemia/reperfusion injury remain incompletely characterized. Autophagic cell death and programmed necrosis are 2 kinds of programmed cell death distinct from apoptosis. Here, we studied the death mechanisms of hippocampal cornu ammonis 1 neuronal death after a 20-minute(More)
Oxidative stress is believed to contribute to neuronal damage induced by cerebral ischemia/reperfusion (I/R) injury. The present study was undertaken to evaluate the possible antioxidant neuroprotective effect of genistein against neuronal death in hippocampal CA1 neurons following transient global cerebral ischemia in the rat. Transient global cerebral(More)
To assess its potential neuroprotective effect against ischemia/reperfusion (IR) injury in mice, bicyclol was administered intragastrically once a day for 3 days. After 6h of bicyclol pretreatment on the third day, forebrain ischemia was induced for 1h by bilateral occlusion of the carotid arteries. After different times of reperfusion, the(More)
Four pairs of XX and XY gonads from Nile tilapia were sequenced at four developmental stages, 5, 30, 90, and 180 days after hatching (dah) using Illumina Hiseq(TM) technology. This produced 28 Gb sequences, which were mapped to 21,334 genes. Of these, 259 genes were found to be specifically expressed in XY gonads, and 69 were found to be specific to XX(More)
BACKGROUND The development of new therapeutic targets and strategies to control highly pathogenic avian influenza (HPAI) H5N1 virus infection in humans is urgently needed. Broadly cross-neutralizing recombinant human antibodies obtained from the survivors of H5N1 avian influenza provide an important role in immunotherapy for human H5N1 virus infection and(More)
The Na+/Ca2+ exchanger (NCX) is an antiporter located in the plasma membrane of many cells, which can maintain the intracellular Ca(2+) homeostasis. Some studies have shown the close relationship of NCX and cerebral ischemia. But controversial results were obtained. Three NCX isoforms, NCX1, NCX2, and NCX3 were distributed selectively in central nervous(More)
Spatial distribution of bacillary dysentery incidence was mapped at the district level in Wuhan, China. And a generalized additive time series model was used to examine the effect of daily weather factors on bacillary dysentery in the high-risk areas, after controlling for potential confounding factors. Central districts were found to be the high-risk(More)
The PI3K-Akt-mTOR pathway plays crucial roles in regulating both innate and adaptive immunity. However, the role of TSC1, a critical negative regulator of mTOR, in peripheral T cell homeostasis remains elusive. With T cell-specific Tsc1 conditional knockout (Tsc1 KO) mice, we found that peripheral naïve CD8(+) T cells but not CD4(+) T cells were severely(More)
