The Yellow River is one of the major rivers with severe runoff declines in China, but there are significant differences changes upper and lower reaches basin among different tributaries. However, characteristic change its spatial heterogeneity not well understood whole basin. In this paper, 48 hydrological stations located mainstream tributaries were selected, meteorological data from 1956 to 2...

OBJECTIVE To screen miRNA profiles of malignantly transformed human bronchial epithelial cells, 16HBE-T, induced by anti-benzo[a]pyrene-trans-7,8-diol-9,10-epoxide (anti-BPDE), and to analyze putative miR-10a targets in 16HBE-T. METHODS A novel microarray platform was employed to screen miRNA profiles of 16HBE-T cells transformed by anti-BPDE. Microarray data for miR-10a and miR-320 were vali...

Higher solid contents (20 % and 40 %) nanocomposites of poly (styrene-co-butyl acrylate) including higher content of Cloisite 30B (7 wt% and 10 wt %) were prepared via miniemulsion polymerization. Stability of the final latexes proved outstanding combination of polymerization procedure and surfactants. Morphological studies revealed by TEM, SAX and XRD showed three structures of core-shell, arm...

nanocomposites based on polyamide 6 (pa6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (eb-g-mah) blends have been prepared via melt mixing. the effect of blend ratio and organoclay concentration onthe crystallization and melting behavior of specimens were studied. three types of commercial organo-modifiedclay (cloisite 30b, cloisite 15a and cloisite 20a) were employed to assess the im...

Development of antibacterial and antibiofilm surfaces is in high demand. In this study, nanocomposite of Poly (ε-caprolactone)/Cloisite 30B was prepared by the solvent casting method. The membranes were characterised by SEM, AFM, and FTIR. Evaluation of water uptake, antimicrobial, antibiofilm, and microbial barrier properties demonstrated a significant antimicrobial and antibiofilm activity ag...

The Qilian Mountains (QMs) act as the “water tower” of Hexi Corridors, playing an important role in regional ecosystem security and economic development. Therefore, it is great significance to understand spatiotemporal characteristics precipitation QMs. This study evaluated performance 21 models phase 6 Coupled Model Intercomparison Project (CMIP6) from 1959 1988 based on ERA5 situ datasets. In...

This study was conducted to investigate corn growth and soil fertility after amendment application of three types in an upland field South Korea. Each the barley straw biochar (BSB, applied at 1,000 kg 10a-1), animal carcass (ACB, 10a-1) along with compost (applied 2,000 bottom ash (BA, 10a-1); Control area only treated compost. The grain yield improved when grown under BSB, ACB, BA Overall, ha...

Gene 10 of bacteriophage T7, which encodes the most abundant capsid protein, has two products: a major product, 10A (36 kDa), and a minor product, 10B (41 kDa). 10B is produced by frameshifting into the -1 frame near the end of the 10A coding frame and is incorporated into the capsid. The frameshift occurs at a frequency of about 10% and is conserved in bacteriophage T3. This study shows that s...

Flavonoids constitute a large class of polyphenolic compounds with cancer preventative properties. We have examined the ability of the natural flavone diosmetin to inhibit proliferation of breast adenocarcinoma MDA-MB 468 and normal breast MCF-10A cells and found that this compound is selective for the cancer cells with slight toxicity in the normal breast cells. Diosmetin was metabolised to th...

Article history: Received 26 June 2017 Accepted 26 June 2017 Available online 27 June 2017 human breast transform MCF-10A human mammary epithelial cells and NMuMG mouse mammary epithelial cells in vitro after several weeks of culture. InMCF-10A cells, these effectswere precededby the induction of DNA double strand breaks (DSB), of which the repair is often intrinsically mutagenic, and were not ...
