To investigate the potential transcriptional regulation and signal pathway of a single microRNA in ischemia-induced retinal neovascularization (NV), we used oxygen-induced retinopathy (OIR) in establishing retinal NV model, and quantitative real-time reverse transcriptase PCR analyzing a microRNA (miR-126) alteration. The mice were treated with plasmid(More)
OBJECTIVE To identify the genetic defect of inherited coagulation factor (F) deficiency in a Chinese family and to explore its molecular mechanism. METHODS The activity and antigen of plasma F were measured by photometric test and enzyme-linked immunosorbent assay, and rocket-electrophoresis, respectively. All the exons and exon-intron boundaries of the(More)
Recent cytotoxicity studies on carbon nanotubes have shown that the biocompatibility of nanomaterial might be determined mainly by surface functionalization, rather than by size, shape, and material. Although the cytotoxicity for individual inorganic hollow nanomaterials should be extensively tested in vitro and in vivo, potential safety concerns about the(More)
OBJECTIVE To investigate the expression of peroxisome proliferator-activated receptors (PPAR)gamma and the effects of PPARgamma ligands on cells growth in colorectal cancer (CRC) cell line HT-29, and to explore whether the activation of PPARgamma by its selective ligand can induce apoptosis and the arrest of the cell cycle in these cells. METHODS A CRC(More)
"Template synthesized" silica nanotubes (SNTs) provide unique features such as end functionalization to control drug release, inner voids for loading biomolecules, and distinctive inner and outer surfaces that can be differentially functionalized for targeting and biocompatibility. Very limited information is available about their biological interactions.(More)
The patient was a 34-year-old man with life-long bleeding episodes, whose hemorrhage problem was characterized predominantly by prolonged bleeding at surgical or traumatic sites. All routine coagulation parameters were within normal ranges. The patient's bleeding tendency was not caused by factor XIII deficiency, alpha2-antiplasmin deficiency, or tissue(More)
Many clinical investigations have suggested that Helicobacter pylori (H. pylori) infection might be associated with immune thrombocytopenic purpura (ITP), but its role in the pathogenesis of ITP is unsettled. In this study, we cultured H. pylori, produced recombinant H. pylori urease (ure) B, and then prepared monoclonal antibody (MoAb) against ureB, 1F11,(More)
In the past few decades, nanoscale materials have been widely used for controlled release applications. Importantly, many researches have focused on multifunctional nanoparticles for targeted delivery of bioactive and imaging agents as therapeutics and diagnostics. Recent advances in nanotechnology have made possible the design and development of tubular(More)
We report a typical case of hematidrosis in a Chinese girl who had experienced frequent bleeding episodes for more than 3 years. During hospitalization, spontaneous bleeding from her intact skin was witnessed by our staff on more than 20 occasions. Characteristically, bloody droplets from the intact skin contained all blood components. Histopathologic(More)
