In the present study, we investigated the preliminary structure, in vitro antioxidant and in vivo hepatoprotective activities of polysaccharides from Cyclina sinensis (CSPS). The analytic results of Fourier transform-infrared spectroscopy indicated the presence of α-type glycosidic linkages in CSPS-1 or CSPS-2, and the average molecular weights for CSPS-1, CSPS-2 and CSPS-3 were 69, 81 and 101 kDa, respectively. For antioxidant activities in vitro, crude CSPS, CSPS-1, CSPS-2 and CSPS-3 showed moderate H2O 2 scavenging activity, lipid peroxidation inhibition effect and strong Fe2+ chelating activity. For hepatoprotective activity in vivo, the administration of CSPS significantly decreased serum levels of alanine aminotransferase and aspartate aminotransferase, inhibited the formation of malondialdehyde and enhanced the activities of liver superoxide dismutase and glutathione peroxidase in carbon tetrachloride-induced liver injury mice. These results suggested that CSPS had potent antioxidant and hepatoprotective activities. © 2012 Elsevier Ltd.

This paper takes full advantage of human visual characteristics to build an objective evaluation method of stereo image quality. This method considers human visual characteristics in evaluating left and right image quality for the first time and uses wavelet transform to stimulate the multi-channel effect in human visual characteristics, weighting wavelet coefficients in different space band contrast sensitivity function and applying Canberra distance to measure left and right image quality. This paper calculates the similarities between the absolute difference image of original left and right image and the absolute difference image of test left and right image to evaluate stereo perception and fittings left and right image quality and stereo perception function to needed objective evaluation model of stereo image quality through linear regression. This paper analyzes the correlation between the predicated value of model and opinion quality score and experiment results show that this model is basically corresponding to subjective evaluation result, which can reflect the quality of stereo images.

While the benefits of cooperation of the diversity of research have been in the literature, cooperation MAC protocol design also led to a lot of attention. In a single-relay repeated request (C-ARQ cooperation agreement, had better be to choose a relay node in a distributed attitude, use different time relay bag. However, back to forward this relay selection plan does not work efficiently in a dense network case; with high collision probability in the struggle of relays may different. In this paper, we put forward an optimal choice of, in order to maximize transmission system energy efficiency reduce collision probability. Energy efficiency performance the optimal transitive the established the simulation results verify the options. © 2011 Published by Elsevier Ltd.

In the present study, we investigated the preliminary characterization, in vitro antioxidant and in vivo heptoprotective activities of polysaccharides from Cipangopaludina chinensis (CCPS). The results of chemical and gas chromatography analysis indicated that CCPS was mostly composed of glucose with high contents of uronic acid and sulfate. For antioxidant activities in vitro, CCPS showed medium lipid peroxidation inhibition effect and high Fe2+ chelating and hydroxyl radical scavenging activities. For hepatoprotective activity in vivo, the administration of CCPS significantly decreased the serum levels of alanine aminotransferase and aspartate aminotransferase, inhibited the formation of malondialdehyde in liver and tumor necrosis factor-alpha (TNF-α) in serum and restored the liver activities of superoxide dismutase, glutathione peroxidase in BCG/LPS-induced immunological liver injury mice. The results suggested that CCPS had a significant protective effect against BCG/LPS-induced immunological liver injury. The hepatoprotective effect of CSPS might be partly due to its immunoregulatory effect by inhibiting TNF-α production and antioxidant activities to protect biological systems against the oxidative stress, which were dependent on the chemical and structural properties of CCPS. Further work on the structure of CCPS is in progress. © 2013 Elsevier Ltd.

The total anthocyanin content (TAC) and the antioxidant activity of the seed and cob from Chinese purple corn (Zea mays L., cv Zihei) extracts were determined by pH-differential method, and DPPH, FRAP, and TEAC methods, respectively. TAC in purple corn cob anthocyanins (PCCAs) extract was higher than TAC in purple corn seed anthocyanins (PCSAs) extract. Compared to bulylated hydroxytoluene (BHT), PCCAs and PCSAs possessed significantly higher antioxidant activities, according to the DPPH, FRAP and TEAC assays. A satisfactory correlation between TAC and antioxidant activity was observed. Result indicated that cyanidin-3-glucoside, pelargonidin-3-glucoside and peonidin-3-glucoside were components in PCSAs extracts, and seven kinds of anthocyanin had been detected and six kinds of anthocyanin in PCCAs extracts were separated and identified them as cyanidin-3-glucoside, pelargonidin-3-glucoside and peonidin-3-glucoside, and their respective malonated counterparts as their anthocyanins using HPLC-MS analysis. Industrial relevance: In the last decades, in interest in anthocyanin pigments has increased because of their possible utilization as natural food colorants and especially as antioxidant and anti-inflammatory agents. Purple corn is a pigmented variety of Z. mays L., originally cultivated in Latin America. Now, this corn variety is mainly grown in China, especially in Shanxi and Anhui Province, could be new and interesting sources to obtain extracts rich in anthocyanins for their use in food, pharmaceutical and cosmetic industries. Our results indicated that the seed and cob of purple corn possessed excellent antioxidant activity, which could lead to increased application of these natural food colorants by the food industry. © 2009 Elsevier Ltd.

A Box-Behnken design was used to obtain the optimal conditions of microwave-assisted extraction (MAE). The effects of operating conditions, such as extraction time, solid-liquid ratio, and microwave irradiation power, on the extraction yield of anthocyanins were studied through a response surface methodology (RSM). The highest total anthocyainin content (TAC) from purple corn cob (185.1 mg/100 g) was obtained at an extraction time of 19 min, a solid-liquid ratio of 1:20, and a microwave irradiation power of 555 W. Six major kinds of anthocyanins were detected and identified as cyanidin-3- glucoside, pelargonidin-3-glucoside, peonidin-3-glucoside, and their respective malonated counterparts. In comparison with the conventional solvent extraction, MAE was highly efficient and rapid in extracting anthocyanins from Chinese purple corn cob. Industrial relevance: In the last decades, the interest in anthocyanin pigments has increased because of their possible utilization as natural food colorants and especially as antioxidant and anti-inflammatory agents. Purple corn cob was the byproduct during the corn processing. Purple corn cob is dark purple to almost black color due to its high content of anthocyanins, which makes this byproduct a good source of anthocyanins. © 2009 Elsevier Ltd. All rights reserved.
