| 6 | Direct-fed microbes: A tool for improving the utilization of low quality roughages in ruminants显示文摘For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of the rumen to improve production efficiency of different ruminant species. Removal and restriction of antibiotics subtherapeutic uses from ruminant diets has amplified interest in improving nutrient utilization and animal performance and search for more safe alternatives. Some bacterial and fungal microorganisms as a direct-fed microbial(DFM) can be the most suitable solutions. Microorganisms that are commonly used in DFM for ruminants may be classified mainly as lactic acid producing bacteria(LAB), lactic acid utilizing bacteria(LUB), or other microorganism's species like Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, Bacillus, Propionibacterium, Megasphaera elsdenii and Prevotellabryantii, in addition to some fungal species of yeast such as Saccharomyces and Aspergillus. A definitive mode of action for bacterial or fungal DFM has not been established; although a variety of mechanisms have been suggested. Bacterial DFM potentially moderate rumen conditions, and improve weight gain and feed efficiency. Fungal DFM may reduce harmful oxygen from the rumen, prevent excess lactate production, increase feed digestibility, and alter rumen fermentation patterns. DFM may also compete with and inhibit the growth of pathogens, immune system modulation, and modulate microbial balance in the gastrointestinal tract. Improved dry matter intake, milk yield, fat corrected milk yield and milk fat content were obtained with DFM administration. However, the response to DFM is not constant; depending on dosages, feeding times and frequencies, and strains of DFM. Nonetheless, recent studies have supported the positive effects of DFM on ruminant performance. | Mona M Y Elghandour Abdelfattah Z M Salem Jose S Martínez Castaeda Luis M Camacho Ahmed E Kholif Juan C Vázquez Chagoyán | 2015 | Journal of Integrative Agriculture2015,14,3: | 7 |
| 7 | 黔中气溶胶传输的^210Pb和^7Be示踪:Ⅱ.月及年时间尺度的剖析显示文摘自2001年12月连续逐周在贵阳观风山附近对近地面空气210Pb-7Be浓度和沉降量的观测表明:区域性降水和气温制约近地面空气210Pb具高浓度'U'型年分布;降水量和平流层向下输送影响近地面空气7Be月均浓度的季节性变化;210Pb/7Be月均浓度比率受控于210Pb变化和富7Be气团下沉的影响。观风山与瓦里关山之间因纬度和海拔的关系,7Be比率急剧震荡,显示出海洋性贫7Be气团入侵对观风山地区的明显影响。2002—2008年间贵阳观风山近地面空气210Pb的年均浓度(2.8±0.6)mBq/m3,约为全球若干站点中最高平均浓度值的4倍;而7Be的年均浓度(4.8±0.6)mBq/m3,与全球高海拔站点长期观测的平均值相当,大约为北半球中纬度对流层顶部附近7Be浓度值(18.0mBq/m3)的1/3.8,显示出低纬度、较高海拔地区的预期水平。2003年,瓦里关山和观风山近地面空气7Be的年均浓度比为3.8,与预期的大气输送和混合作用基本一致。7Be月均浓度的增大趋势反映出受太阳黑子数减少的变化关系,其影响底线大约为4mBq/m3;7Be年均浓度波动的增大趋势反映出受太阳黑子数降低的可能影响。贵阳观风山降水中7Be和210Pb的体积加权浓度分别为0.72Bq/L和0.27Bq/L;年沉降通量分别为0.080Bq/(cm2.a)和0.031Bq/(cm2.a)。数值模拟显示出全球空气210Pb高浓度区和高沉降通量环带分布,印证了洱海和红枫湖沉积物7Be和137Cs蓄积的模拟结果。 | 万国江 郑向东 Lee H N Bai Z G 万恩源 王仕禄 杨伟 苏菲 汤洁 王长生 黄荣贵 刘鹏 | 2010 | 地球科学进展2010,25,5: | 6 |

| 10 | Effects of cellulase and xylanase enzymes mixed with increasing doses of Salix babylonica extract on in vitro rumen gas production kinetics of a mixture of corn silage with concentrate显示文摘An in vitro gas production(GP) technique was used to investigate the effects of combining different doses of Salix babylonica extract(SB) with exogenous fibrolytic enzymes(EZ) based on xylanase(X) and cellulase(C), or their mixture(XC; 1:1 v/v) on in vitro fermentation characteristics of a total mixed ration of corn silage and concentrate mixture(50:50, w/w) as substrate. Four levels of SB(0, 0.6, 1.2 and 1.8 m L g–1 dry matter(DM)) and four supplemental styles of EZ(1 μL g–1 DM; control(no enzymes), X, C and XC(1:1, v/v) were used in a 4×4 factorial arrangement. In vitro GP(m L g–1 DM) were recorded at 2, 4, 6, 8, 10, 12, 24, 36, 48 and 72 h of incubation. After 72 h, the incubation process was stopped and supernatant p H was determined, and then filtered to determine dry matter degradability(DMD). Fermentation parameters, such as the 24 h gas yield(GY24), in vitro organic matter digestibility(OMD), metabolizable energy(ME), short chain fatty acid concentrations(SCFA), and microbial crude protein production(MCP) were also estimated. Results indicated that there was a SB?EZ interaction(P<0.0001) for the asymptotic gas production(b), the rate of gas production(c), GP from 6 to 72 h, GP2(P=0.0095), and GP4(P=0.02). The SB and different combination of enzymes supplementation influenced(P<0.001) in vitro GP parameters after 12 h of incubation; the highest doses of SB(i.e., 1.8 m L g–1 DM), in the absence of any EZ, quadratically increased(P<0.05) the initial delay before GP begins(L) and GP at different incubation times, with lowering b(quadratic effect, P<0.0001) and c(quadratic effect, P<0.0001; linear effect, P=0.0018). The GP was the lowest(P<0.05) when the highest SB level was combined with cellulose. There were SB?EZ interactions(P<0.001) for OMD, ME, the partitioning factor at 72 h of incubation(PF72), GY24, SCFA, MCP(P=0.0143), and p H(P=0.0008). The OMD, ME, GY24 and SCFA with supp lementation of SB extract at 1.8 m L g–1 DM were higher(P<0.001) than the other treatments, however,PF72 was lower(quadratic effect, P=0.0194) than the other levels. Both C and X had no effect(P>0.05) on OMD, p H, ME, GY24, SCFA and MP. The combination of SB with EZ increased(P<0.001) OMD, ME, SCFA, PF72 and GP24, whereas there was no impact on p H. It could be concluded that addition of SB extract, C, and X effectively improved the in vitro rumen fermentation, and the combination of enzyme with SB extract at the level of 1.2 m L g–1 was more effective than the other treatments. | Abdelfattah Z M Salem German Buendía-Rodríguez Mona M M Elghandour María A Mariezcurrena Berasain Francisco J Pea Jiménez Alberto B Pliego Juan C V Chagoyán María A Cerrillo Miguel A Rodríguez | 2015 | Journal of Integrative Agriculture2015,14,1: | 4 |

| 13 | Oxygen and Nitrogen Effects on MC Carbide in K465 Nickel-Base Superalloy显示文摘Effects of oxygen and nitrogen on MC carbide in nickel-base superalloy K465 were investigated, because neither of the two gas elements was found to decide MC carbide morphology monotonically. The morphology of MC carbide under alloy solidified in conventional investment casting condition was observed to transform from script-type to block-type with the total oxygen and nitrogen content (gas content) in samples rising up from 1.2×10-6 mol/g to 2.6×10-6 mol/g. The area fraction and composition of the MC carbide also varied with increase of gas content. However, the morphology of MC carbide kept to be script-type even when gas content was up to 3.4×10-6 mol/g in samples solidified with a much higher cooling rate. These results indicate that effects of gas content on formation of MC carbide can be observed in specimens solidified with low cooling rate, but such changes in MC carbide cannot be found when the cooling rate is high. | Wang L N Zheng Q Sun X F Guan H R Hu Z Q | 2009 | 稀有金属材料与工程2009,38,A03: | 4 |
| 14 | Effects of tyrosine kinase inhibitor E7080 and eNOS inhibitor L-NIO on colorectal cancer alone and in combination显示文摘Objective:To investigate the effects of E7080 and N5-(1-iminoethyl)-L-ornithine dihydrochloride(L-NIO)on colorectal cancer alone and in combination.Methods:HT29 colorectal cancer cell line from Sap Institute was used.Real-time cell analysis(xCELLigence system)was performed to determine the effects of E7080 and L-NIO on colorectal cell proliferation.While apoptosis was determined with Annexin V staining,and the effect of agents on angiogenesis was determined with chorioallantoic membrane(CAM)model.Results:We found that E7080 has a strong antiproliferative effect with an half maximum inhibition of concentration(IC50)value of 5.60×10–8mol/L.Also it has been observed that E7080 showed antiangiogenic and apoptotic effects on HT29 colorectal cancer cells.Antiangiogenic scores of E7080 were 1.2,1.0 and 0.6for 100,10 and 1 nmol/L E7080 concentrations,respectively.Furthermore,apoptosis has been detected in71%of HT29 colorectal cancer cells after administration of 100 nmol/L E7080 which may indicate strong apoptotic effect.Meanwhile administration of L-NIO alone did not show any effect,but the combination of E7080 with L-NIO increased the antiproliferative,antiangiogenic and apoptotic effects of E7080.Conclusions:Results of this study indicate that E7080 may be a good choice in treatment of colorectal tumors.Furthermore the increased effects of E7080 when combined with L-NIO raise the possibility to use a lower dose of E7080 and therefore avoid/minimize the side effects observed with E7080. | Ahmet Altun Tijen Kaya Temiz Ezgi Balc Zübeyde Ak n Polat Mustafa Turan | 2013 | Chinese Journal of Cancer Research2013,25,5: | 4 |
