Selective reduction of nitrite to nitrogen by polyaniline-carbon nanotubes composite at neutral pH.

The selective reduction of nitrite (NO) to nitrogen by chemical reductant is a desirable strategy to remove NO from polluted water and wastewater. However, the residue and reuse of chemical reductant are two main issues to be addressed. Herein, a novel polyaniline-carbon nanotubes composite (PANI-CNTs) was developed by in-situ polymerization to selectively reduce NO to nitrogen gas (N).

Selective reduction of nitrate to nitrogen by Fe-Cu-CuFeO composite coupled with carbon dioxide anion radical under UV irradiation.

Zero-valent iron (Fe) has been widely used for the reduction of nitrate, but the end reduction product is mainly ammonium. Here, a novel strategy for selective reduction of nitrate (NO) to nitrogen gas (N) with high efficiency and N selectivity was investigated using Fe-based material (Fe-Cu-CuFeO) combined with citric acid (CA) and ultraviolet (UV) irradiation. In this strategy, the nitrate was firstly reduced to nitrite (NO) by Fe-Cu-CuFeO/UV process, and then the produced NO could be further reduced to N by carbon dioxide anion radicals (CO) which was generated from CA that was added later.

Selective reduction of nitrite to nitrogen gas by CO anion radical from the activation of oxalate.

Nitrite (NO) reduction by carbon dioxide anion radical (CO) from the activation of small molecule carboxylic acid was investigated to selectively reduce nitrite to nitrogen gas (N) However, the CO generation efficiency from the activation of small molecule carboxylic acid needs to be enhanced to increase the NO reduction efficiency. In this study, a novel and promising process for selective NO reduction was proposed based on activation of oxalic acid (OA) by UV radiation coupled with Fe. In Fe(III)/OA/UV system, the activation of OA by photo-induced electron transfer process of Fe(III)-oxalate complex and by •OH radical from the photolysis of Fe or NO could promote the generation of CO radical, which enhanced the NO reduction.

A novel CNTs-FeO synthetized via a ball-milling strategy as efficient fenton-like catalyst for degradation of sulfonamides.

A novel composite (CNTs-FeO) was synthesized by a ball-milling strategy and characterized by BET, SEM, FTIR, XRD and VSM. The as-fabricated CNTs-FeO was used to remove six sulfonamides by a Fenton degradation process, including sulfanilamide (SAM), sulfamerazine (SMR), sulfadimethoxine (SMX), sulfadiazine (SDZ), sulfamethazine (SMT) and sulfametoxydiazine (SMD). The degradation behaviors of six sulfonamides in CNTs-FeO/HO system and the relationship between molecular structure of sulfonamides and their degradation behaviors were investigated systematically.

Five patients after prosthetic tricuspid valve, who received pacemaker implantation via coronary sinus during Oct, 2011 and Jul, 2014, were enrolled. Pacemakers were implanted via coronary vein in 5 patients without complications. The stimulation thresholds keep stable and symptoms (such as short breath and fatigue) were disappeared during the follow-up.

Data in support of comparative proteomics analysis of superior and inferior spikelets in hybrid rice during grain filling and response of inferior spikelets to drought stress using isobaric tags for relative and absolute quantification.

We provide the raw data for protein and peptide identification and quantization of superior and inferior spikelets in hybrid rice during grain filling. The mass spectrometry proteomics data have been deposited to the Proteome Xchange Consortium via the PRIDE partner repository with the dataset identifier PXD001046. Our data presented here is also related to the article "Comparative proteomics analysis of superior and inferior spikelets in hybrid rice during grain filling and response of inferior spikelets to drought stress using isobaric tags for relative and absolute quantification "in the Journal of Proteomics [1].

Rice stripe virus affects the viability of its vector offspring by changing developmental gene expression in embryos.

Plant viruses may affect the viability and development process of their herbivore vectors. Small brown planthopper (SBPH) is main vector of Rice stripe virus (RSV), which causes serious rice stripe disease. Here, we reported the effects of RSV on SBPH offspring by crossing experiments between viruliferous and non-viruliferous strains.

Comparative proteomics analysis of superior and inferior spikelets in hybrid rice during grain filling and response of inferior spikelets to drought stress using isobaric tags for relative and absolute quantification.

Unlabelled: The biological functions of the differentially abundant proteins between superior and inferior spikelet grains were investigated based on the isobaric tags for relative and absolute quantification to further clarify the mechanism of rice grain filling at the proteomic level, as well as the response of inferior spikelets to drought dress (-20kPa or -40kPa). Compared with superior spikelets, inferior ones had lower sink strength due to the lower sink activities (lower abundances of ADP-glucose pyrophosphorylase, granule-bound starch synthase, starch branching enzyme and pullulanase) and smaller sink sizes (lower abundances of structural proteins). The slower and later grain filling resulted from the weaker decomposition and conversion of photoassimilate and the slower cell division.

Investigation on subcellular localization of Rice stripe virus in its vector small brown planthopper by electron microscopy.

Background: Rice stripe virus (RSV), which is transmitted by small brown planthopper (Laodelphax striatellus Fallén, SBPH), has been reported to be epidemic and cause severe rice stripe disease in rice fields in many East Asian countries, including China. Investigation on viral localization in the vector is very important for elucidating transmission mechanisms of RSV by SBPH. In this study, transmission electron microscopy and immuno-gold labeling technique were used to investigate the subcellular localization of the ribonucleoproteins (RNPs) of RSV in the digestive tract, muscles, ovary and testes of SBPH.
