Influence of Rotational Speed on Isothermal Piston Compression System.

An isothermal piston is a device that can achieve near-isothermal compression by enhancing the heat transfer area with a porous media. However, flow resistance between the porous media and the liquid is introduced, which cannot be neglected at a high operational speed. Thus, the influence of rotational speed on the isothermal piston compression system is analyzed in this study.

A review on Fenton process for organic wastewater treatment based on optimization perspective.

Water pollution caused by organic wastewater has become a serious concern worldwide. Fenton oxidation process is one of the most effective and suitable methods for the abatement of organic pollutants. However, the process has three obvious shortcomings: the narrow working pH range, the high costs and risks associated with handling, transportation and storage of reagents (HO and catalyst), the significant iron sludge related second pollution.

TGF-beta1 induces human bronchial epithelial cell-to-mesenchymal transition in vitro.

The subepithelial fibrosis component of airway remodeling in asthma is mediated through induction of transforming growth factor-beta1 (TGF-beta1) expression with consequent activation of myofibroblasts to produce extracellular matrix proteins. The number of myofibroblasts is increased in the asthmatic airway and is significantly correlated with the thickness of lamina reticularis. However, much is still unknown regarding the origin of bronchial myofibroblasts.

[The investigation of the relationship between Leptin-insulin resistance and pulmonary function in patients with chronic obstructive pulmonary disease with acute exacerbation].

Objective: To investigate the relationship between Leptin-insulin resistance and pulmonary function in patients with chronic obstructive pulmonary disease (COPD) with acute exacerbation.

Methods: Fifty-six patients with COPD with acute exacerbation were divided into two groups according to the fasting plasma glucose level [the hyperglycemia group: fasting blood glucose (FBG)> or =6.2 mmol/L, n=42.
