Aptamers, single stranded DNA or RNA molecules, generated by a method called SELEX (systematic evolution of ligands by exponential enrichment) have been widely used in various biomedical applications. The newly developed Cell-SELEX (cell based-SELEX) targeting whole living cells has raised great expectations for cancer biology, -therapy and regenerative(More)
Ginkgo biloba extract EGb761 is widely used to treat patients with learning and memory impairment in Alzheimer’s disease and Parkinson’s disease in China. However, it is not yet clear whether the analog of EGb761 (EGb) has a protective effect on the learning and memory damage induced by chronic fluorosis. In this study, 30 Wistar rats were randomly divided(More)
Oligonucleotides (ODN) with hexameric motifs containing central unmethylated CpG dinucleotides are immunostimulatory. Also ODN with continuous guanosines (polyG motif) show a wide range of immunological activity. Depending on the position, the chemical property of the ODN backbone and the cell type, polyG motifs have either an enhancing or a suppressing(More)
Gas chromatography-mass spectrometry (GC-MS) profiles were generated from U87 glioma cells and human mesenchymal stem cells (hMSC). 37 metabolites representing glycolysis intermediates, TCA cycle metabolites, amino acids and lipids were selected for a detailed analysis. The concentrations of these metabolites were compared and Pearson correlation(More)
OBJECTIVE Functioning pituitary macroadenoma and giant adenoma have large growth volumes and endocrinological abnormalities, requiring proper medical intervention. In this retrospective study, microneurosurgery and subsequent gamma knife radiosurgery (GKRS) is assessed for efficacy and safety for the treatment of functioning pituitary macroadenoma and giant(More)
EGb-761 is commonly used as a treatment for ischemic brain injury, neurodegenerative diseases and some types of tumors (Christen and Maixent, in Cell Mol Biol 48(6):601–611, 2002). However, it is unclear whether EGb-761 affects the proliferation of cells exposed to fluoride. In this study, the proliferation and apoptosis of PC-12 cells exposed to fluoride(More)
