Public concern and metabolic drain were the main driving forces for the development of a selectable marker-free transformation system. We demonstrated here the production of transgenic tobacco plants using a non-selection approach by Agrobacterium tumefaciens-mediated transformation. A. tumefaciens-infected leaf explants were allowed to produce shoots on a(More)
(−)-Epigallocatechin-3-gallate (EGCG) is the most abundant catechin in green tea. In this study, we found that hepatitis C virus (HCV) infection was significantly suppressed by EGCG in an HCV cell culture (HCVcc) system using a JFH1-GFP chimeric virus, with a 50 % effective concentration (EC50) of 17.9 μM. The inhibitory activity of EGCG was confirmed by(More)
Advanced removal of phosphate by low-cost adsorbents from municipal wastewater or industrial effluents is an effective and economic way to prevent the occurrence of eutrophication. Here, we proposed a novel method to immobilize hydrous zirconium oxide nanoparticle within quaternary-aminated wheat straw, and obtained an inexpensive, eco-friendly(More)
OBJECTIVE To investigate the diagnosis and treatment of delayed post-pancreaticoduodenectomy arterial bleeding (DPPAB). METHODS Records of 336 patients who underwent pancreaticoduodenectomy (PD) between January 2000 and December 2010 were retrospectively analyzed. Detailed data of patients with DPPAB were assessed by a thorough review of medical records.(More)
The present study developed a polymer-based hybrid sorbent (HFO-001) for highly efficient removal of heavy metals [e.g., Pb(II), Cd(II), and Cu(II)] by irreversibly impregnating hydrated Fe(III) oxide (HFO) nanoparticles within a cation-exchange resin D-001 (R-SO(3)Na), and revealed the underlying mechanism based on X-ray photoelectron spectroscopy (XPS)(More)
Many tumor immunotherapy efforts are focused on the generation of strong T-cell response against tumor antigens. However, strong T-cell response does not always coincide with tumor rejection, for which upregulated expression of immunoinhibitory molecules may be responsible. In this study, the treatment with heat shock protein 70 (HSP70) vaccine induced an(More)
BACKGROUND Soluble programmed death-1 (sPD-1) has been proven to bind PD-1 ligands (PD-Ls), block PD-L/PD-1 interactions, and enhance the cytolysis of cytotoxic T-lymphocytes (CTLs). CH50, a two-domain molecule of fibronectin, has been shown to suppress the development of tumors via enhancing the activity of macrophages. This study evaluated the influence(More)
Pseudomonas syringae pv. panici is a phytopathogenic bacterium causing brown stripe disease in economically important crops worldwide. Here, we announce the draft genome sequence of Pseudomonas syringae pv. panici LMG2367 to provide further valuable insights for comparison of the pathovars among species Pseudomonas syringae.
Small-diameter vascular grafts can easily lead to thrombosis and intimal hyperplasia. So the rate of the long-term patency is not satisfactory. Scaffolds that can support the growth of cells and remain stable and passable in vivo are in great demand. Vascular scaffolds were fabricated by electrospinning RGD-recombinant spider silk protein (pNSR32),(More)
The Three Gorges Project is the largest hydro project in the world, and the water level of the Three Gorges Reservoir (TGR) is dynamic and adjustable with the aim of flood control and electrical power generation. It is necessary to investigate the pollutants and their underlying contamination processes under dynamic water levels to determine their(More)
