Highly efficient removal of hexavalent chromium by magnetic Fe-C composite from reed straw and electric furnace dust waste.

Reed straw and electric furnace dust (EFD) waste were used to prepare magnetic Fe-C composite (EFD&C) by co-precipitation and high-temperature activation method to remove Cr(VI) from water. The magnetic EFD&C owned a large specific surface (536.61 m/g) and a porous structure (micropores and mesopores), and had an efficient removal capacity for Cr(VI).

Study on miRNAs in Pan-Cancer of the Digestive Tract Based on the Illumina HiSeq System Data Sequencing.

Objective: miRNA has gained attention as a therapeutic target in various malignancies. The proposal of this study was to investigate the biological functions of key miRNAs and target genes in cancers of the digestive tract which include esophageal carcinoma (ESCA), gastric adenocarcinoma (GAC), colon adenocarcinoma (COAD), and rectal adenocarcinoma (READ).

Materials And Methods: After screening differentially expressed miRNAs (DEMIs) and differentially expressed mRNAs (DEMs) in four digestive cancers from The Cancer Genome Atlas (TCGA) database, the diagnostic value of above DEMIs was evaluated by receiver-operating characteristic (ROC) curve analysis.

Thermodynamic simulation on mineralogical composition of CaO-SiO2-Al2O3-MgO quaternary slag system.

It is necessary to elucidate the crystallization thermodynamic of mineralogical phases during the cooling process of the molten BFS with different chemical composition, because the high-melting point mineral phase maybe crystallized during the fiber forming and thereafter cooling process. Thermodynamic calculation software FactSage6.4 and the hot remelting experiments were performed to explore the influence of basicity, Al2O3 content and MgO content on the crystallization of mineralogical components and their transformation.

Quality evaluation of five commercial enzyme linked immunosorbent assay kits for detecting aflatoxin b1 in feedstuffs.

The objective of this study was to evaluate the quality of five commercial enzyme linked immunosorbent assay (ELISA) kits (A, B, C, D, and E) from different suppliers for detecting aflatoxin B1 (AFB1). AFB1-free corn samples supplemented with different levels of AFB1 (5, 10, and 20 μg/kg) were used as positive controls and 6 replicates of each control sample were tested to evaluate the accuracy and precision of these kits. In addition, we also evaluated the performance of these ELISA kits for AFB1 in 30 feed samples, including corn, distillers dried grains with soluble, wheat samples, soybean meal, and poultry feed, which were verified by high performance liquid chromatography.

HPV16E7-specific siRNA inhibits cell proliferation in CaSki cells.

High-risk human papilloma virus (HPV) infection is the main cause for the genesis of cervical carcinomas. After infection, E6 and E7 genes of HPV were integrated to the genome of the cervical epithelium. Continued expression of the transforming oncoproteins E6 and E7 not only drives the neoplastic progression in cervical epithelium, but also plays an important role in maintaining the malignant phenotype of cervical cancer cells.

[Long-term sorption /desorption behavior of pyrene in soils].

Long-term sorption/desorption behavior of pyrene in six types of soils are investigated. The results show that long-term sorption and desorption entail two phases, including initially rapid process followed by a slow sorption/desorption. When soil organic matter (SOM) content was below 1%, the constant of sorption Kd of dissimilar soils increased with SOM content under different equilibrium time.
