Soil moisture evidence of self-restoration in coal mining subsidence area of Shendong Mining area: Cognition based on stable isotopes.

The Shendong mining area is the largest coal production base in China. However, the area is dry and water scarce, and the ecological environment is fragile. Large scale mining of shallow and thick coal seam in mining area may affect surface moisture and threaten surface ecological security.

Decolorization and detoxication of malachite green by engineered Saccharomyces cerevisiae expressing novel thermostable laccase from Trametes trogii.

Malachite Green (MG) is a widely used industrial dye that is hazardous to health. Herein, the decolourisation and detoxification of MG were achieved using the engineered Saccharomyces cerevisiae expressing novel thermostable laccase lcc1 from Trametes trogii. The engineered strain RCL produced a high laccase activity of 121.

Enrichment of boron element in follicular fluid and its potential effect on the immune function.

The blood-follicle barrier (BFB) between the blood and follicular fluid (FF) can maintain the microenvironment balance of oocyte. Boron, an exogenous environmental trace element, has been found to possibly play an important role in oocyte maturation. This study aimed to examine the distribution characteristics of boron across the BFB and find the potential effect of boron on FF microenvironment.

Effect of diode laser combined with minocycline hydrochloride in nonsurgical periodontal therapy: a randomized clinical trial.

Background: This study aimed to assess the effect of diode laser combined with minocycline hydrochloride in conventional nonsurgical periodontal therapy.

Methods: Ninety-two patients and 1206 teeth were included in this study. The patients were diagnosed moderate or severe periodontal diseases with the presence of teeth in at least 3 quadrants in the oral cavity.

Overexpression of MMP14 predicts the poor prognosis in gastric cancer: Meta-analysis and database validation.

Background: Plenty of studies have showed matrix metalloproteinase 14 (MMP14) expression might be associated with the prognosis of gastric cancer (GC). However, no definite conclusion has been obtained for the contradictory results.

Methods: We searched PubMed, Web of science, Embase, and Cochrane library for eligible studies.

Hydraulic Integrated Interconnected Regenerative Suspension: Modeling and Characteristics Analysis.

A novel suspension system, the hydraulic integrated interconnected regenerative suspension (HIIRS), has been proposed recently. This paper demonstrates the vibration and energy harvesting characteristics of the HIIRS. The HIIRS model is established as a set of coupled, frequency-dependent equations with the hydraulic impedance method.

MicroRNA-125b may function as an oncogene in lung cancer cells.

The present study aimed to investigate the biofunctions of microRNA (miR)‑125b on lung cancer cells. A miR genechip array was used to examine the differential expression of miRs between 95D lung cancer cells and 16 human bronchial epithelial (HBE) cells. Overexpression of miR‑125b was observed in the cell lines and in the lung carcinoma tissues compared with the adjacent tissues, confirmed using reverse transcription quantitative polymerase chain reaction.

Selecting temperature for protein crystallization screens using the temperature dependence of the second virial coefficient.

Protein crystals usually grow at a preferable temperature which is however not known for a new protein. This paper reports a new approach for determination of favorable crystallization temperature, which can be adopted to facilitate the crystallization screening process. By taking advantage of the correlation between the temperature dependence of the second virial coefficient (B(22)) and the solubility of protein, we measured the temperature dependence of B(22) to predict the temperature dependence of the solubility.
