Effective treatment of levofloxacin wastewater by an electro-Fenton process with hydrothermal-activated graphite felt as cathode.

The performance of the cathode significantly affects the ability of the electro-Fenton (EF) process to degrade chemicals. In this study, a simple method to modify the graphite felt (GF) cathode was proposed, i.e.

Aberrant Methylation-Mediated Silencing of lncRNA MEG3 Functions as a ceRNA in Esophageal Cancer.

Maternally expressed gene 3 (MEG3), a long non-coding RNA (lncRNA), has tumor-suppressor properties and its expression is lost in several human tumors. However, its biological role in esophageal squamous cell carcinoma (ESCC) tumorigenesis is poorly defined. The present study determined the role and methylation status of MEG3 in esophageal cancer cells and ESCC clinical specimens, and further observed the competing endogenous RNA (ceRNA) activity of MEG3 in the pathogenesis and development of ESCC.

Aberrant methylation-mediated downregulation of long noncoding RNA LOC100130476 correlates with malignant progression of esophageal squamous cell carcinoma.

Background: Dysregulated long non-coding RNAs (lncRNAs) are involved in many complicated human diseases including cancer.

Aims: To determine the role and methylation status of a new lncRNA LOC100130476 in the pathogenesis of esophageal squamous cell carcinoma (ESCC).

Methods: One hundred and twenty three ESCC patients with tumor tissues and corresponding adjacent normal tissues were enrolled.

Methylation-mediated downregulation of long noncoding RNA LOC100130476 in gastric cardia adenocarcinoma.

Accumulating evidences indicate that long non-coding RNAs (lncRNAs) play important roles in several biological processes and dysregulated lncRNAs are involved in different kinds of cancer and are associated with carcinogenesis, metastasis, and prognosis of cancer. The role of a new lncRNA LOC100130476 in gastric cardia adenocarcinoma (GCA) has remained unknown. The present study investigated the role and methylation status of LOC100130476 in the pathogenesis of GCA, and further evaluated the potential prognostic role of LOC100130476 in GCA.

Crystal structure of tetra-aquabis(1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ido)magnesium.

The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the Mg(II) atom is coordinated in a slightly distorted octa-hedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites.
