Neuroprotection strategies are of great importance in the treatment of ischemic brain injury. Screening of our in-stock coumarin derivatives identified compound 1 as exhibiting neuroprotective activity. Subsequently, a structural optimization was carried out, which led to the discovery of the potent compound 20. This compound significantly attenuated the(More)
A simple and effective electrostatic method has been used to attach MoO3 belts onto a graphene template. The MoO3/graphene composite was annealed under a H2/Ar atmosphere; the obtained MoO2 maintained its original structure and exhibited microstructures such as flaws, etc. We investigated the electrocatalytic behavior of the MoO2/graphene composite towards(More)
Carbon nanodots (CDs) of uniform size were prepared simply by the hydrothermal decomposition of folic acid (FA) precursor at various reaction temperatures. The CDs formed via dehydration of FA at 260 °C contributed the strongest photoluminescence (PL) signal and the highest quantum yield at about 68%, without assistance of any passivation agent. The effects(More)
Ginsenoside Rg1 (Rg1), the major effective component of ginseng, has been shown to have multiple bioactivities, but low oral bioavailability. The aim of this study was to develop a simple, sensitive and rapid high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, which could be used to validate and quantify the concentrations of(More)
Detection of single-cell gene expression with high spatial and sequence resolution is a key challenge in single cell biology. Herein, we propose a robust method for the direct detection of mRNA, termed target RNA-initiated rolling circle amplification, which enables imaging of mRNA with single-nucleotide and near-single-molecule resolution in single cells.(More)
