In this study, we report on the degradation of microcystin-LR (MC-LR) by gas-liquid interfacial discharge plasma. The influences of operation parameters such as average input voltage, electrode distance and gas flow rate are investigated. Experimental results indicate that the input voltage and gas flow rate have positive influences on MC-LR degradation, while the electrode distance has a negative one. After 6 min discharge with 25 kV average input voltage and 60 L/h air aeration, the degradation rate of MC-LR achieves 75.3%. H 2O2 and O3 generated by discharge both in distilled water and MC-LR solution are measured. Moreover, an emission spectroscopy is used as an indicator of the processes that take place on the gas-liquid boundary and inside plasma. Varied types of radicals (O, ·OH, CO, O3, etc.) are proved to be present in the gas phase during gas-liquid interfacial discharge.

Myricetin and myricitrin are naturally occurring flavonoids have been suggested to play a role in inhibition of proliferation and transformation of carcinogenic cell. However, the underlying molecular mechanisms of their activity have not yet to be revealed. The aim of the present study was to clarify the molecular mechanisms of apoptosis cell on the prostate cancer induced by myricetin, myricitrin, quercetin and quercitrin. The MTT assay confirmed that myricetin had the strongest inhibitory effect on human prostate cancer cell line PC-3, myricitrin was second, and quercitrin was the weakest. A noticeable synergistic effect was observed with the inhibition of cell proliferation when myricetin was used in combination with myricitrin. In the concentration range of 37.5-300 μmol/L, the inhibitory effects of these flavonoids were enhanced with increasing dose and treatment time. The acridine orange analysis and annexin V-FITC/PI double-staining results confirmed that myricetin and myricitrin were effective in inducing PC-3 cell apoptosis. The results showed that myricetin was more effective than myricitrin in inducing cell apoptosis. The apoptosis rate increased with increasing flavonoid concentration in a dose dependent manner. A synergistic effect was observed on the apoptosis rate when myricetin was used in combination with myricitrin. © 2012 Elsevier Ltd. All rights reserved.

Microcystins (MCs), the most common class of cyanobacterial toxins and emerging drinking water contaminants, are harmful to animal and human health. We report on the effective removal of microcystin-LR (MC-LR) using water surface plasma discharge in the presence of carbon xerogels that have been doped with various levels of manganese (Mn). Mn-doped carbon xerogels were prepared by a sol-gel method and characterized via several techniques: N2 adsorption, X-ray diffraction, X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy. The results indicate that different concentrations of dopant change the texture properties, but that they have no obvious influence on the chemical properties or the surface morphologies of Mn-doped carbon xerogels. Water treatment in which MC-LR was removed using water surface plasma discharge was performed. With the addition of carbon xerogels, the removal rate of MC-LR increased from 75.3% to 90.2% after a 6-min treatment. An oxidation-adsorption kinetic model that produces a good fit to the experimental data is proposed. © 2013 Copyright Taylor and Francis Group, LLC.

Linear oscillatory motors with short stroke represent an excellent alternative in linear compressor applications. A novel halbach-type transverse-flux linear oscillatory motor (HTLOM) with two stators was presented, which has the advantage of without moving iron core, compact structure, light weight, easy-stacked stator and smooth thrust force characteristic. Based on the principle analysis, the static thrust force was calculated by three-dimensional (3-D) finite element analysis (FEA). Then the dynamic simulation was presented for the resonant characteristics of current, displacement, active and reactive power and power factor versus frequency. The analysis result shows that the novel HTLOM with two stators is suitable for linear compressor application, and its maximum efficiency can be achieved at velocity resonance by spring stiffness selection. The conclusions are very significant for the further driving control in industrial usage. © (2013) Trans Tech Publications, Switzerland.

Ganoderma, as a Chinese traditional medicine, has multiple bioactivities. However, industrial production was limited due to low yield during Ganoderma fermentation. In this work, sucrose was found to greatly enhance intracellular polysaccharide (IPS) content and specific extracellular polysaccharide (EPS) production rate. The mechanism was studied by analyzing the activities of enzymes related to polysaccharide biosynthesis. The results revealed that sucrose regulated the activities of phosphoglucomutase and phosphoglucose isomerase. When glucose and sucrose mixture was used as carbon source, biomass, polysaccharide and ganoderic acids (GAs) production was greatly enhanced. A sucrose fed-batch strategy was developed in 10-L bioreactor, and was scaled up to 300-L bioreactor. The biomass, EPS and IPS production was 25.5, 2.9 and 4.8 g/L, respectively, which was the highest biomass and IPS production in pilot scale. This study provides information for further understanding the regulation mechanism of Ganoderma polysaccharide biosynthesis. It demonstrates that sucrose fed-batch is a useful strategy for enhancing Ganoderma biomass, polysaccharide and GAs production.
