The property-activity relationship is usually established to understand the toxicity mechanism of nanomaterials. In the present study, different morphological Cu2O nanocrystals, octahedrons, truncated octahedrons, cuboctahedrons, and cubes, were synthesized to precisely tuning the {100} and {111} facet percentages in purpose of systematically investigating the toxicity role of crystallographic facets in BEAS-2B and RAW 264.7 cells. It was found that the toxicity of polyhedral Cu2O nanocrystals was highly dependent on the exposed {100} surface after short-term exposure because {100} facets could produce more reactive oxygen species (ROS) than {111} facets, however, after long-term exposure, their toxicity showed again the correlation with total surface property because toxic copper ions were largely released from the whole nanocrystal surface irrespective of {100} or {111} facet and this copper dissolution caused the collapse of surface crystals and the vanishing of ROS...

The majority of patients with epithelial ovarian cancer are diagnosed at a late stage when peritoneal metastases exist, however, there is little knowledge of the metastatic process in this disease setting. In this study, we report the identification of the long non-coding RNA LINC00092 as a nodal driver of metastatic progression mediated by cancer-associated fibroblasts (CAF). Pro-metastatic properties of CAF in vitro and in vivo were found to associate with elevated expression of the chemokine CXCL14. In clinical specimens, elevated levels of CXCL14 in CAF also correlated with poor prognosis...

BACKGROUND: Inflammatory reactions induced by microglia in the brain play crucial roles in ischemia/reperfusion (I/R) cerebral injuries. Microglia activation has been shown to be closely related to TLR4/NF-κB signal pathways. Salvianolic acids for injection (SAFI) have been used in clinical practice to treat ischemic stroke with reported neuroprotective effects; however, the underlying mechanisms are still uncertain. OBJECTIVE AND METHODS: First, we studied the effect of SAFI on inflammatory responses in LPS-stimulated BV-2 microglia...

Diffusion-weighted magnetic resonance imaging is a non-invasive imaging method that has been increasingly used in neuroscience imaging over the last decade. Partial volume effects (PVEs) exist in sampling signal for many physical and actual reasons, which lead to inaccurate fiber imaging. We overcome the influence of PVEs by separating isotropic signal from diffusion-weighted signal, which can provide more accurate estimation of fiber orientations. In this work, we use a novel response function (RF) and the correspondent fiber orientation distribution function (fODF) to construct different signal models, in which case the fODF is represented using dictionary basis function...

Hepatocellular carcinoma (HCC) generally possesses a high resistance to chemotherapy. Given that autophagy is an important factor promoting tumor chemoresistance and HCC express low level of miR-26, we aim to investigate the functional role of miR-26 in autophagy-mediated chemoresistance of HCC. We found that chemotherapeutic drug doxorubicin (Dox) induced autophagy but decreased the level of miR-26a/b in HCC cells. Activating autophagy using rapamycin can directly downregulate the level of miR-26a/b in HCC cells...

Aprotic Li-O2 batteries have attracted worldwide interest owing to their ultra-high theoretical energy density. However, the practical Li-O2 batteries still suffer from high charge overpotential and low energy efficiency resulting from the sluggish kinetics in electrochemically oxidizing the insulating lithium peroxide (Li2O2). Recently, dissolved redox mediators in the electrolyte have enabled the effective catalytic oxidation of Li2O2 at the liquid-solid interface. Here, we report that the incorporation of N-methylphenothiazine (MPT), as a redox shuttle in Li-O2 batteries, provides a dramatic reduction in charge overpotential to 0...
