There has been considerable interest in the use of persulfate for in situ chemical oxidation of organic contaminants in soils, sediments, and groundwater. Since humic acid (HA) exists ubiquitously in these environmental compartments, its redox active functional moieties, such as quinones, may play an important role in the oxidation processes of persulfate(More)
We investigated the activation of hydrogen peroxide (H2O2) by biochars (produced from pine needles, wheat, and maize straw) for 2-chlorobiphenyl (2-CB) degradation in the present study. It was found that H2O2 can be effectively activated by biochar, which produces hydroxyl radical ((•)OH) to degrade 2-CB. Furthermore, the activation mechanism was elucidated(More)
The transformation of the sulfonamide antimicrobial sulfamethazine (SMZ) by a synthetic analogue of the birnessite-family mineral vernadite (δ-MnO(2)) was studied. The observed pseudo-first-order reaction constants (k(obs)) decreased as the pH increased from 4.0 to 5.6, consistent with the decline in δ-MnO(2) reduction potential with increasing pH.(More)
Subnanoscale zerovalent iron (ZVI) synthesized using smectite clay as a template was utilized to investigate reduction of decabromodiphenyl ether (DBDE). The results revealed that DBDE was rapidly debrominated by the prepared smectite-templated ZVI with a reaction rate 10 times greater than that by conventionally prepared nanoscale ZVI. This enhanced(More)
Animal and cell experiments showed that inositol hexaphosphate (IP6) was protective on neurons in parkinson's disease (PD) model, but the underlying mechanism of this action was not extensively elucidated. To address this question, we established 6-hydroxydopamine (6-OHDA) induced human dopaminergic cell line SH-SY5Y as PD cell model and testified the(More)
A new rhabdovirus, tentatively designated as hybrid snakehead rhabdovirus C1207 (HSHRV-C1207), was first isolated from a moribund hybrid snakehead (Channa maculata × Channa argus) in China. We present the complete genome sequence of HSHRV-C1207 and a comprehensive sequence comparison between HSHRV-C1207 and other rhabdoviruses. Sequence alignment and(More)
PURPOSE To evaluate the efficacy and safety of microwave ablation combined with transcatheter arterial chemoembolization for unresectable large-sized hepotocellular carcinoma. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained. Between May 2004 and December 2006, 34 consecutive patients with large unresectable(More)
This study aimed to evaluate the effects of adding chromic chloride (CrCl3) in the drinking water of chickens. Hyland brown male chickens were randomly divided into four groups. Three groups orally received 1/2 LD50, 1/4 LD50, and 1/8 LD50 CrCl3mgkg(-1) body weight daily for 42d. The fourth group was treated with water. The chickens were sacrificed at 14,(More)
Pyrolysis of vegetative biomass into biochar and application of the more stable form of carbon to soil have been shown to be effective in reducing the emission of greenhouse gases, improving soil fertility, and sequestering soil contaminants. However, there is still lack of information about the impact of biochar amendment in agricultural soils on the(More)
The microRNAs represent a class of noncoding RNAs with short length and play diverse roles in many biological processes. Despite tremendous effects have been devoted, the role of miR-635 in non-small cell lung cancer (NSCLC) remains elusive. Here we report a potential tumor suppressive function of miR-635 in NSCLC. By microRNA screening based on invasion(More)
