Highly efficient activation of peroxymonosulfate by biomass juncus derived carbon decorated with cobalt nanoparticles for the degradation of ofloxacin.

The cobalt nanoparticles decorated biomass Juncus derived carbon (Co@JDC) was prepared by facile calcination strategy and applied to activate peroxymonosulfate (PMS) for eliminating ofloxacin (OFX) in the water environment. The results of catalytic experiments show that 97% of OFX degradation efficiency and 70.4% of chemical oxygen demand removal rate are obtained within 24 min at 0.

Ellagic acid inhibits high glucose-induced injury in rat mesangial cells via the PI3K/Akt/FOXO3a signaling pathway.

The pathological damage of mesangial cells serves an important role in the occurrence and development of diabetic nephropathy. Ellagic acid has been reported to possess antioxidant, antitumor, antiviral and anti-inflammatory properties in several diseases, but the roles of ellagic acid in diabetic nephropathy are unclear. The main aim of the present study was to investigate the effect of ellagic acid on high glucose-induced mesangial cell damage.

miR-25-3p promotes proliferation and inhibits autophagy of renal cells in polycystic kidney mice by regulating ATG14-Beclin 1.

MicroRNAs are involved in the regulation of the autophagy and proliferation in several diseases. This study aims to verify the role of miR-25-3p in the proliferation and autophagy of renal cells in polycystic kidney disease (PKD). We found that kidney to body weight and blood urea content were increased in PKD mice.

microRNA-612 suppresses the malignant development of non-small-cell lung cancer by directly targeting bromodomain-containing protein 4.

Aberrant expression of microRNAs (miRNAs) in non-small-cell lung cancer (NSCLC) has been reported. Dysregulation of miRNAs exerts tumor-suppressing or tumor-promoting actions on the pathology and biological behaviors of NSCLC. miR-612 is associated with many types of human cancer; however, the expression, potential roles, and regulatory mechanisms of miR-612 in NSCLC remain unclear.

LncRNA MIR210HG promotes proliferation and invasion of non-small cell lung cancer by upregulating methylation of CACNA2D2 promoter via binding to DNMT1.

In recent years, a large number of studies have shown that differentially expressed lncRNAs are capable of promoting the occurrence and development of tumors by regulating cell proliferation and differentiation. However, the biological effects of lncRNAs in non-small cell lung cancer (NSCLC) are still needed to be further investigated. The differentially expressed lncRNAs in NSCLC tissues in the downloaded profiles from GEO database were analyzed and further verified in 100 pairs of NSCLC samples collected in our hospital.

Prognosis and survival analysis of paraquat poisoned patients based on improved HPLC-UV method.

Unlabelled: Paraquat (PQ) has caused deaths of numerous people around the world. In order to assess the lethal plasma concentration, the patients who acquired acute PQ intoxication were analyzed by plasma concentration monitoring. The plasma PQ concentrations were determined by high performance liquid chromatography (HPLC) which used 5-bromopyrimidine as internal standard and trichloroacetic acid-methanol (1:9) as protein precipitant.

High glucose promotes tumor invasion and increases metastasis-associated protein expression in human lung epithelial cells by upregulating heme oxygenase-1 via reactive oxygen species or the TGF-β1/PI3K/Akt signaling pathway.

Background: Growing evidence indicates that heme oxygenase-1 (HO-1) is up-regulated in malignancies and subsequently alters tumor aggressiveness and various cancer-related factors, such as high glucose (HG) levels. HO-1 expression can be induced when glucose concentrations are above 25 mM; however, the role of HO-1 in lung cancer patients with diabetes remains unknown. Therefore, in this study we investigated the promotion of tumor cell invasion and the expression of metastasis-associated proteins by inducing the up-regulation of HO-1 expression by HG treatment in A549 human lung epithelial cells.

Conversion of bone marrow mesenchymal stem cells into type II alveolar epithelial cells reduces pulmonary fibrosis by decreasing oxidative stress in rats.

Pulmonary fibrosis is an irreversible chronic progressive fibroproliferative lung disease, which usually has a poor prognosis. Previous studies have confirmed that the transplantation of bone marrow mesenchymal stem cells (MSCs) significantly reduces lung damage in a number of animal models. However, the underlying mechanism involved in this process remains to be elucidated.

Genetic variants in ADAM33 are associated with airway inflammation and lung function in COPD.

Background: Genetic factors play a role in the development and severity of chronic obstructive pulmonary disease (COPD). The pathogenesis of COPD is a multifactorial process including an inflammatory cell profile. Recent studies revealed that single nucleotide polymorphisms (SNPs) within ADAM33 increased the susceptibility to COPD through changing the airway inflammatory process and lung function.

[The effect of marrow mesenchymal stem cell transplantation on pulmonary fibrosis in rats].

Objective: To study the possible mechanisms of marrow mesenchymal stem cells (MSC) in therapy of bleomycin (BLM)-induced pulmonary fibrosis in rats.

Methods: Fifty-four female Wistar rats were randomly divided into a control group, a BLM group and a MSC group. The control group received intratracheal normal saline, the BLM group received intratracheal instillation of bleomycin, and the MSC group was injected with male rat MSC solution of 0.

Association of ADAM33 gene polymorphisms with COPD in a northeastern Chinese population.

Background: Chronic obstructive pulmonary disease (COPD) is influenced by both environmental and genetic factors. ADAM33 (a disintegrin and metalloproteinase 33) has been one of the most exciting candidate genes for asthma since its first association with the disease in Caucasian populations. Recently, ADAM33 was shown to be associated with excessive decline of lung function and COPD.
