Ensifer sp. according to its physiological-biochemical properties and the analysis of its 16S rRNA gene sequence (GenBank Accession No. EU303300). Above 85% of 100 mg/L difenoconazole was degraded by strain B2 within 24 h. The optimal pH and temperature for degradation were 7.0 and 30-35 degrees C respectively. The degrading rate showed a positive correlation with the amount of initial inoculum size while a negative correlation with the initial concentration of difenoconazole. No degradation occurred if the initial concentration of difenoconazole excessed 400 mg/L in mineral salt medium.

AB - Single-phase zeolite NaA was synthesized from fly ash using two-stage method. The structure and performance of the products were characterized. With the static method, the adsorption properties of NaA zeolite to Cu(II), Cr(VI) and Zn(II) in aqueous solution was studied and adsorption mechanism was discussed from kinetic point of view. Under the experimental concentration and pH value, the equilibrium adsorption data fitted to Langmuir isotherms and the greatest adsorption capacity of Cu(II), Cr(VI) and Zn(II) was 82.30, 65.96 and 47.78 mg/g, respectively. The existing way and size of three heavy metal ions in aqueous solution were important influential factors on adsorption behavior. Moving Boundary Model analysis showed that the adsorption rate of Cu(II) and Zn(II) was mainly governed by liquid film diffusion, and intra-particle diffusion was important controlling factor for the adsorption rate of Cr(VI). The adsorption processes of three heavy metal ions followed a pseudo-second-order kinetic model.

AB - In order to evaluate safety of food from Yangtze River Delta, one of rapidly developing regions in China, 155 rice grain samples were collected from high risk area in 10 towns of Changshu City in South Jiangsu in 2005. Analysis methods of ICP-AES and HG-AFS were used to determine content of Cd, Cr, Cu, Pb, Zn, Ni, Hg and As in rice flesh and hull samples. According to relative national standards of China and human health risk assessment, pollution and safety of rice flesh and hull in study area were evaluated. There was an identity between the sequence of heavy metals in rice flesh and hull of 10 study towns, and the distribution characteristics of some metals in rice flesh and hull of these towns were different. Some heavy metals in rice flesh were correlated with them in hull, especially Cu, Zn and Ni. Pb, Hg, As and Cd in some rice flesh were above the national standards when evaluated with single factor index method. Pb exceeded the standard seriously by 29.7%, followed with Hg (20.6%). As and Pb in some hull were above the national standards, they exceeded their standards by 3.2% and 1.3%, respectively. The composite pollution indexes of rice flesh ranged from 0.30 to 3.50, and 28.4% of them were contaminated with metals. The highest arithmetical mean composite pollution index (1.42) was found in Xingang town, which could be categorized as light pollution. However, other towns could be regarded as no pollution from the means of them. The composite pollution indexes of hull ranged from 0.15 to 2.46, and 3.2% of them were polluted. From the means all towns were in security. Results of exposure risk assessment for the rice flesh suggesting that rice grown in Changshu posed Cu and Zn potential risk to food safety and rice from some towns possessed Pb potential risk.

AB - Eighteen surface sediment samples were collected from Taihu Lake and analysed for polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyl (PCBs) with GC-EI-MS. The concentrations of 28 PAH compounds detected ranged from 90.6 to 1.04x103 ng/g, with the highest concentration observed in sediments of Zhushanhu Lake. Concentrations of 16 PAHs identified as priority pollutants was in the range of 63.1-885 ng/g. The PCBs concentrations ranged from 1.35 to 13.8 ng/g, and the highest concentration was found in Xintanggang area. The PAHs in the study area were mainly originated from pyrogenic source as indicated by the ratios of PAH homologues, factor analysis and multiple line regression. Furthermore, the combustion of coal or wood and the combustion of oil accounted for 45% and 50% of the total PAHs in the surface sediments, respectively. The PCB homologue profiles indicated that the source of PCBs in sediments was a mixture of Aroclor 1242 and Aroclor 1254. The total dioxin equivalents of PAHs and PCBs in the sediments from Taihu Lake ranged from 0.64 to 3.35 pg/g. The risk evaluation suggested that the PAHs and PCBs in the sediments of the study area might pose little harm to the environment.

AB - The influences of intensity of ultraviolet (UV) light, light-barrier property of packaging film on the fat photo-oxidation and accelerated shelf life of cookies were studied. Unpacked cookies were stored at a temperature of 40 degrees C and a relative humidity (RH) of 50% for 10 to 65 days, with an intensity of the UV light of 0.3, 1.9 and 9.5 micro W/cm2. Meanwhile, the same batch of cookies was packed with oriented nylonlpolyethylene, polyethylene terephthalatel oriented nylon/polyethylene and bi-oriented polypropylene/vacuuming aluminized casting polypropylene and stored at the same temperature and RH and UV-light intensity of 1.9 micro W/cm2 for more than 40 days. The peroxide values (POV) of cookies were measured under the storage conditions. The results showed that the intensity of the UV light and light-barrier property of film had notable influence on the photo-oxidation rate and accelerated shelf life of cookies. According to the threshold of POV, unpacked cookies were rancid less than 32 and 11 days when exposed in light of 1.9 and 9.5 micro W/cm2 in the accelerated test, respectively. In contrast, the shelf life of unpacked cookies in darkness, or cookies packed in high light-barrier package was more than 75 days. Logarithm of POV and store-time relationship under different UV-light illumination was successfully fitted by linear regression under the same temperature, RH and the accelerated shelf-life-based oxide index was estimated.

AB - Triptolide is a diterpene triepoxide isolated from the traditional Chinese medicinal vine Trypterygium wilfordii Hook f. (T. wilfordii). It possesses multiple biological activities, such as antitumor, immunosuppression, and antifertility. Previous studies suggested that triptolide might be a potential candidate for post-testicular male contraceptive agent. Nevertheless, the mechanisms of triptolide-induced reproductive toxicity remain unclear. In the present study, the results of reverse-transcription PCR and Western blotting revealed that triptolide inhibited the expression of Cx43 compared with the different effect of estradiol in cultured SCs from male rats. Further computational study revealed that triptolide can bind to the active site of human estrogenic 17beta-hydroxysteroid dehydrogenase and human estrogen receptor beta . Therefore, our results indicated that male reproductive toxicity induced by triptolide was associated with the effects on intratesticular estrogen levels and estrogen receptors rather than its cytotoxicity.

AB - Objective: A study was conducted to evaluate the effect of bone mesenchymal stem cells (BMSCs) on the healing of tendon-bone junction in a bone tunnel and to provide experimental evidence of labelling and tracing the stem cell. Methods: BMSCs from rats were harvested by adherent separation screening method and labelled by SPIO and DiI. Thirty-nine 8-week old rats were randomly divided into two groups: 21 rats injected with double-labeled BMSCs and Pluronic F-127 as experimental group and 18 rats injected with Pluronic F-127 alone as control group. In each group, biomechanical analysis was carried out to assess the effect of healing at 2, 4, and 8 weeks. The transplanted BMSCs were traced by fluorescence microscope at 2, 4, and 8 weeks and 7.0T MR instantly, 3 and 7 days after operation. Results: BMSCs were labelled effectively by SPIO and DiI. DiI-labeled positive cells were observed between tendon and bone with fluorescence microscopy at 2, 4 and 8 weeks. No significant signal changes of tendon-bone interface could be observed by 7.0T MR. Biomechanically, maximum pullout load had no statistical difference between the experimental group and control group at 2 weeks. At 4 and 8 weeks, the experimental group had significantly higher maximum pullout load compared with the control group (
