Calprotectin and Neutrophil Gelatinase-Associated Lipocalin As Biomarkers of Acute Kidney Injury in Acute Coronary Syndrome.

Background: Acute kidney injury (AKI) is increasingly being seen in patients with acute coronary syndromes (ACS) and it is associated with higher short-term and long-term morbidity and mortality. Therefore, it is of paramount importance to identify those ACS patients at risk for the development of AKI. The objective of this study was to evaluate two different plasma biomarkers calprotectin and neutrophil gelatinase-associated lipocalin (NGAL) in early detecting the development of AKI in ACS patients.

Diatom-based water-table reconstruction in Sphagnum peatlands of northeastern China.

Peatlands are important ecosystems for biodiversity conservation, global carbon cycling and water storage. Hydrological changes due to climate variability have accelerated the degradation of global and regional ecosystem services of peatlands. Diatoms are important producers and bioindicators in wetlands, but comprehensive diatom-based inference models for palaeoenvironmental reconstruction in peatlands are scarce.

Thermal Stability of Octadecyltrichlorosilane and Perfluorooctyltriethoxysilane Monolayers on SiO.

Using in situ ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS) measurements, the thermal behavior of octadecyltrichlorosilane (OTS) and 1H, 1H, 2H, and 2H-perfluorooctyltriethoxysilane (PTES) monolayers on SiO substrates has been investigated. OTS is thermally stable upto 573K with vacuum annealing, whereasPTES starts decomposing at a moderate temperature between 373 K and 423K. Vacuum annealing results in the decomposition of CF and CF species rather than desorption of the entire PTES molecule.

Enhanced photoresponse of epitaxially grown ZnO by MoO surface functionalization.

ZnO has broad applications in optoelectronic devices, including ultraviolet light emitters and photodetectors. Herein we report the impact of MoO surface functionalization on the photoresponse of epitaxially grown ZnO. Under illumination with 350 nm UV light, the photocurrent of ZnO is found to be enhanced by 2.

Apigenin suppresses mouse peritoneal fibrosis by down-regulating miR34a expression.

Peritoneal fibrosis is a severe side-effect of chronic peritoneal dialysis in patients with end-stage renal disease, but not enough effective therapeutic drugs are currently available in clinics. The aim of this study was to evaluate the effects of apigenin and miRNA on the progression of peritoneal fibrosis. We treated isolated mouse mesothelial peritoneal cells (MMCs) with high glucose (HG), to induce fibrosis.

Yi-qi-yang-yin-tang increases the sensitivity of KG1a leukemia stem cells to daunorubicin by promoting cell cycle progression and regulating the expression of PTEN, TOPOII and mTOR.

The present study aimed to investigate the effects of serum containing a combination of yi-qi-yang-yin-tang (YQYYT) and daunorubicin (DNR) on multidrug resistance in KG1a leukemia stem cells (LSCs). The effects of YQYYT and DNR on proliferation, cell cycle progression and the expression of phosphatase and tensin homolog (PTEN), topoisomerase II (Topo II) and mechanistic target of rapamycin (mTOR) in KG1a cells were investigated using cell counting kit-8 assay, flow cytometry, reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. It was revealed that YQYYT-containing serum did not affect proliferation of KG1a cells compared with the blank group.
