| 1 | Cover Crop and Irrigation Effects on Soil Microbial Communities and Enzymes in Semiarid Agroecosystems of the Central Great Plains of North America显示文摘盖子庄稼能由增加碳(C) 供应在土壤微生物学上有有益的效果,但是这些有益的效果能被降水条件调制。这研究的目的是比较休闲冬季小麦(Triticum aestivum L.) 旋转到在在半干旱的美国高平原的 rainfed 和灌溉条件下面的几盖子庄稼冬季小麦旋转。实验在科罗拉多在二个地点,在内布拉斯加的 Sidney,和 Akron 被执行,美国与三次在在盖子庄稼结束的 2012-2013 的土壤采样,种的小麦,和小麦成熟。实验包括了四单个种类的盖子庄稼, 10 种类混合物,和一个休闲处理。测量的变量是土壤 C 和氮(N) ,由甲基酉旨(名声) 介绍的丰满的酸的土壤社区结构,和土壤 -glucosidase,-glucosaminidase, 和 phosphodiesterase 活动。休闲处理,缺乏生活植物,在盖子庄稼结束减少了大多数名声的集中。全部的名声集中与盖子庄稼生物资源被相关(R = 0.62 在 Sidney 并且 0.44 在 Akron ) 。等到种的小麦,有灌溉的有益的效果,它在 mycorrhizal 和原生动物门标记引起了增加。在小麦成熟,土壤名声上的盖子庄稼和灌溉效果减退了,但是灌溉在 Akron 在 -glucosidase 和 phosphodiesterase 活动上有积极效果,它二个地点中是更干燥的。盖子庄稼和灌溉是慢的影响土壤 C 集中。我们的结果证明盖子庄稼在在半干旱的基于小麦的旋转和灌溉的微生物引起的社区能提高的土壤上有短命效果土壤酶活动。在半干旱的环境,更长的时间跨度可能被需要在土壤上看见盖子庄稼的有益的效果微生物引起的社区结构,土壤酶活动,和土壤 C 隐遁。 | Francisco J.

| 2 | Towards a standard diet-induced and biopsy-confirmed mouse model of non-alcoholic steatohepatitis: Impact of dietary fat source显示文摘BACKGROUND The trans-fat containing AMLN(amylin liver non-alcoholic steatohepatitis,NASH)diet has been extensively validated in C57BL/6J mice with or without the Lep^ob/Lep^ob(ob/ob)mutation in the leptin gene for reliably inducing metabolic and liver histopathological changes recapitulating hallmarks of NASH.Due to a recent ban on trans-fats as food additive,there is a marked need for developing a new diet capable of promoting a compatible level of disease in ob/ob and C57BL/6J mice.AIM To develop a biopsy-confirmed mouse model of NASH based on an obesogenic diet with trans-fat substituted by saturated fat.METHODS Male ob/ob mice were fed AMLN diet or a modified AMLN diet with trans-fat(Primex shortening)substituted by equivalent amounts of palm oil[Gubra amylin NASH,(GAN)diet]for 8,12 and 16 wk.C57BL/6J mice were fed the same diets for 28 wk.AMLN and GAN diets had similar caloric content(40%fat kcal),fructose(22%)and cholesterol(2%)level.RESULTS The GAN diet was more obesogenic compared to the AMLN diet and impaired glucose tolerance.Biopsy-confirmed steatosis,lobular inflammation,hepatocyte ballooning,fibrotic liver lesions and hepatic transcriptome changes were similar in ob/ob mice fed the GAN or AMLN diet.C57BL/6J mice developed a mild to moderate fibrotic NASH phenotype when fed the same diets.CONCLUSION Substitution of Primex with palm oil promotes a similar phenotype of biopsyconfirmed NASH in ob/ob and C57BL/6J mice,making GAN diet-induced obese mouse models suitable for characterizing novel NASH treatments. | Michelle L Boland Denise Oro Kirstine S T■lb■l Sebastian T Thrane Jens Christian Nielsen Taylor S Cohen David E Tabor Fiona Fernandes Andrey Tovchigrechko Sanne S Veidal Paul Warrener Bret R Sellman Jacob Jelsing Michael Feigh Niels Vrang James L Trevaskis Henrik H Hansen | 2019 | World Journal of Gastroenterology2019，25，33： | 3 |
| 3 | Feeding Biochar to Cows:An Innovative Solution for Improving Soil Fertility and Farm Productivity显示文摘Addition of biochar produced through thermal decomposition of biomass has been seen as a strategy to improve soils and to sequester carbon(C), but wide scale implementation of the technology requires to devise innovative profitable solutions. To develop biochar utilisation with an integrated system approach, an innovative program was implemented in 2012 on a 53-ha farm in Western Australia to determine the costs and benefits of integrating biochar with animal husbandry and improvement of pastures. Biochar was mixed with molasses and fed directly to cows. The dung-biochar mixture was incorporated into the soil profile by dung beetles.We studied the changes in soil properties over 3 years. Biochar extracted from fresh dung and from the soil to a depth of 40 cm was characterised. A preliminary financial analysis of the costs and benefits of this integrated approach was also undertaken. The preliminary investigation results suggested that this strategy was effective in improving soil properties and increasing returns to the farmer. It was also concluded that the biochar adsorbed nutrients from the cow's gut and from the dung. Dung beetles could transport this nutrient-rich biochar into the soil profile. There was little evidence that the recalcitrant component of the biochar was reduced through reactions inside the gut or on/in the soil. Further research is required to quantify the long-term impact of integrating biochar and dung beetles into the rearing of cows. | Stephen JOSEPH Doug POW Kathy DAWSON David R.G.MITCHELL Aditya RAWAL James HOOK Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Joshua RUST Scott DONNE Paul MUNROE Ben PACE Ellen GRABER Torsten THOMAS Shaun NIELSEN Jun YE Yun LIN PAN Genxing LI Lianqing Zakaria M.SOLAIMAN | 2015 | Pedosphere2015，25，5： | 2 |
