BACKGROUND AND PURPOSE Little research regarding genotypes and clopidogrel response related to acute ischemic stroke has been published. This study was conducted to investigate whether the polymorphisms of receptors or enzymes involved in the metabolic process of clopidogrel affect clopidogrel response and prognosis related to acute stroke. METHODS A(More)
OBJECTIVE To investigate the protective effects of hydrogen peroxide preconditioning (HPP) on the pheochromocytoma (PC12) cells treated with 1-methyl-4-phenylpyridinium (MPP(+)) and to explore the potential mechanisms. METHODS The viability and apoptosis of PC12 cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)(More)
The purpose of this study is to investigate the possible mechanism and the neuroprotective effect of human urinary kallidinogenase (HUK) in cerebral ischemia. The mouse middle cerebral artery occlusion (MCAO) model was used. Mice were treated with HUK (20 PNAU/g per day, intravenous) or saline as control, from the beginning of reperfusion to 72 h.(More)
It has been reported that icariin protects neurons against ischemia/reperfusion injury. In this study, we found that icariin could enhance neuronal viability and suppress neuronal death after oxygen and glucose deprivation (OGD). Further study showed that neuroprotection by icariin was through the induction of Sirtuin type 1 (SIRT1), an effect that was(More)
The purpose of this study was to look for alterations in β-amyloid peptide (Aβ) metabolism-related molecules in predementia, the early stage of Alzheimer’s disease (AD). AlCl3 (Al) and d-galactose (D-gal) were used to induce the mouse model for predementia and AD. Protein expression of β-amyloid (Aβ), β-secretase (BACE1), neprilysin (NEP), insulin degrading(More)
MicroRNAs (miRNAs) play an important role in the development, differentiation, proliferation, survival, and oncogenesis of cells and organisms including nervous system. However, the role of miRNAs in primary neurons of dorsal root ganglion (DRG) after injury was not clear. In this study, a miRNA microarray analysis was performed, and a total of 21 miRNAs(More)
Hereditary spinocerebellar ataxia (SCA) is a devastating, incurable disease. Stem-cell-based therapies represent new promise for clinical research in neurology. The objectives of this study were to assess the feasibility, efficacy, and potential toxicity of human umbilical cord mesenchymal stem cells (UCMSCs) therapy in patients with SCA. Sixteen(More)
1. Histone deacetylase (HDAC) inhibitors exert neuroprotection in both cellular and animal models of ischaemic stroke. However, which HDAC isoform (or isoforms) mediates this beneficial effect has not yet been determined. 2. In the present study, gene levels of the HDAC isoforms were determined in the mouse cortex using reverse transcription-polymerase(More)
BACKGROUND Previous studies have indicated that thrombin (TM) may play a major role in brain edema after intracerebral hemorrhages (ICHs). However, the mechanism of TM-induced brain edema is poorly understood. In this study, we explored the effect of TM on the permeability of the blood brain barrier (BBB) and investigated its possible mechanism, aiming at(More)
OBJECTIVE To investigate the relationship between tumor necrosis factor (TNF) A-308 gene polymorphism and aggressive periodontitis (AgP). METHODS Anti-coagulated peripheral blood samples were obtained from 64 AgP patients, and 78 healthy controls (H). Genomic DNA was extracted from each sample. The TNF A-308 gene polymorphism was detected by standard(More)
