| 1 | 鄂尔多斯盆地侏罗纪煤的煤岩特征及成因分析显示文摘鄂尔多斯盆地侏罗系发育多层厚煤层,煤质优良,储量巨大,且构造简单,埋深较浅,具有很大的开采价值。该岩系独特的煤岩特征与其成煤沼泽环境有密切联系,即内陆湖泊发育有关的河流体系上部的一系列高位沼泽;泥炭埋藏后继续经历不同程度的氧化阶段,使得煤岩组分中惰性组分含量普遍偏高,而镜质组分普遍经受一定程度的丝炭化作用而成为半镜质体。研究表明盆地中侏罗系煤系中煤的宏观煤岩主要以半暗煤和暗淡煤为主,半亮煤和光亮煤占次要地位;在盆地边缘,特别是靠近盆地北部物源地区,半暗煤、暗淡煤含量比例较高,往南向盆地中心部位半亮煤和光亮煤逐渐增多,表明沉积环境和成煤沼泽环境对煤岩组分具有主要控制作用;含煤岩系中,特别是煤层下部砂岩越厚,颗粒越粗,显微煤岩组分中丝质体含量越高,而且其结构完整、清晰,半镜质体含量也越高,植物细胞结构越完整和规则。埋藏后顶底板岩性还会继续影响煤岩组分的演化过程。煤层顶底板砂体由于物性条件好,孔隙水仍可长时间处于氧化与循环流通状态,使得各煤岩组分能长时间处于氧化状态,有利于丝炭化作用进行;相反,在盆地中心,湖泊相发育,泥炭被埋藏之后迅速被泥岩覆盖,煤层很快处于还原缺氧环境,凝胶化作用得以充分进行,镜质组的含量就会增高。研究还发现,壳质组常常在煤层中的某一部位富集,虽然整个煤层中其平均含量不高,但是却对煤层的总体生烃能力会有很大贡献。以往的研究成果中,壳质组含量常常被低估,尤其是呈流动状态的沥青质体,因为它最容易流动到刚性比较强的丝质体内部或各种裂隙中而常常被忽略,在以后的研究中值得加以重视。 | 黄文辉 敖卫华 翁成敏 肖秀玲 刘大锰 唐修义 陈萍 赵志根 万欢 FINKELMAN Bob | 2010 | 现代地质2010,24,6: | 64 |
| 2 | 藏北高原地区地表辐射出支和能量平衡的季节变化显示文摘对青藏高原地区地表能量的研究是一个十分重要的问题.基于中日合作项目“全球协调加强观测计划之亚澳季风青藏高原试验”(CAMP/Tibet)在2001年8月至2002年9月的观测数据资料,分析研究了青藏高原藏北地区地表能量,即净辐射通量、感热通量、潜热通量和土壤热通量等的变化规律,获得了有关藏北高原地表能量的新认识. | 马伟强 马耀明 李茂善 Z.(Bob)SU 王介民 | 2005 | 冰川冻土2005,27,5: | 45 |
| 3 | Neutrophil extracellular trap cell death requires both autophagy and superoxide generation显示文摘嗜中性的细胞外的陷井(网) 是能套住并且降级的细胞外的染色质结构微生物。他们从激活称为网络房间死亡,或 NETosis 的一个房间死亡程序的 neutrophils 产生。NETosis 的激活被显示了包含 NADPH oxidase 活动,原子信封的崩溃和大多数小粒膜,网的原子染色质和形成的 decondensation。我们报导在 phorbol,十四酸盐醋酸盐(PMA ) 刺激了 neutrophils,细胞内部的染色质 decondensation 和网形成跟随 autophagy 和 superoxide 生产,哪个被要求调停导致 PMA 的 NETosis 并且独立于对方发生。从有长期的 granulomatous 疾病的病人的 Neutrophils,缺乏 NADPH oxidase 活动,仍然展出导致 PMA 的 autophagy。相反地,导致 PMA 的 NADPH oxidase 活动没被 autophagy 的药理学抑制影响。有趣地,任何一个 autophagy 的抑制或 NADPH oxidase 阻止细胞内部的染色质 decondensation,它为 NETosis 和网形成是必要的,并且导致 apoptosis 的特点描绘的房间死亡。当 autophagy 或 NADPH oxidase 活动被阻止时,这些结果显示 apoptosis 可能为 NETosis 作为一个备份节目工作。 | Quinten Remij sen Tom Vanden Berghe Ellen Wirawan Bob Asselbergh Eef Parthoens Riet De Rycke Sam Noppen Michel Delforge Jean Wlllems Peter Vandenabeele | 2011 | Cell Research2011,21,2: | 46 |
| 4 | 细小泥沙粒径对迷宫流道灌水器堵塞的影响显示文摘为探明细小泥沙粒径对迷宫流道灌水器抗堵塞性能的影响,该文以内镶片式斜齿形迷宫流道灌水器为研究对象,应用类短周期堵塞测验方法对8种粒径小于0.1 mm的泥沙颗粒进行浑水测试。在此基础上,分析了泥沙粒径和含沙量对灌水器堵塞的影响,探讨引起灌水器发生堵塞时的敏感粒径范围与含沙量水平。试验结果表明:对于粒径小于0.1 mm的细小颗粒,含沙量是引起灌水器堵塞的主要原因,当浑水含沙量水平大于1.25 g/L时,影响尤其显著,呈正相关关系;粒径对堵塞的影响并不是单调的递增或递减,堵塞发生的敏感粒径范围在0.03~0.04 mm之间。试验结果有助于进一步提高含沙水源滴灌的应用水平。 | 刘璐 牛文全 Bob Zhou | 2012 | 农业工程学报2012,28,1: | 41 |

Overcasting technology is gaining traction and has enabled mixed material designs for automotive sub-systems such as engine cradles and instrument panel beams. Simulation tools developed to predict the interfacial interactions of the dissimilar components and the structural integrity of the overcast systems are being validated in the casting trials. | Alan A.Luo Anil K.Sachdev Bob R.Powell | 2010 | China Foundry2010,7,4: | 29 |
| 6 | Electro-acupuncture to prevent prolonged postoperative ileus:A randomized clinical trial显示文摘AIM:To examine whether acupuncture can prevent prolonged postoperative ileus(PPOI)after intraperitoneal surgery for colon cancer. METHODS:Ninety patients were recruited from the Fudan University Cancer Hospital,Shanghai,China. After surgery,patients were randomized to receive acupuncture(once daily,starting on postoperative day 1, for up to six consecutive days)or usual care.PPOI was defined as an inability to pass flatus or have a bowel movement by 96 h after surgery.The main outcomes were time to first flatus,time to first bowel movement, and electrogastroenterography.Secondary outcomes were quality of life(QOL)measures,including pain, nausea,insomnia,abdominal distension/fullness,and sense of well-being. RESULTS:No significant differences in PPOI on day 4 (P=0.71)or QOL measures were found between the groups.There were also no group differences when the data were analyzed by examining those whose PPOI had resolved by day 5(P=0.69)or day 6(P= 0.88).No adverse events related to acupuncture were reported. CONCLUSION:Acupuncture did not prevent PPOI andwas not useful for treating PPOI once it had developed in this population. | M Kay Garcia Joseph S Chiang Bob Thornton J Lynn Palmer Jennifer McQuade Lorenzo Cohen | 2010 | World Journal of Gastroenterology2010,16,1: | 27 |

| 8 | Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians. | Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li | 2014 | World Journal of Gastrointestinal Pathophysiology2014,5,4: | 13 |

| 16 | Practical starter pig amino acid requirements in relation to immunity,gut health and growth performance显示文摘Immune system activation begins a host of physiological responses.Infectious agents are recognized by monocytes and macrophages which in turn stimulate cytokine production.It is the hormone-like factors called cytokines that orchestrate the immune response.The classic responses observed with immune system activation and cytokine production include:anorexia,fever,lethargy,recruitment of other immune cells,and phagocytosis.While production of immune system components is known to require some amino acids,increases in amino acid requirements are more than offset by the associated decrease in protein accretion and increased muscle protein degradation that also accompanies immune system activation.However,the biggest impact of cytokine production is a decrease in feed intake.Therefore,as feed intake decreases,the energy needed to drive protein synthesis is also decreased.This suggests that diets should still be formulated on a similar calorie:lysine ratio as those formulated for non-immune challenged pigs.The evidence is sparse or equivocal for increasing nutrient requirements during an immune challenge.Nutritionists and swine producers should resist the pressure to alter the diet,limit feed,or add expensive feed additives during an immune challenge.While immune stimulation does not necessitate changes in diet formulation,when pigs are challenged with non-pathogenic diarrhea there are potential advantages on gut health with the increased use of crystalline amino acids rather than intact protein sources(i.e.,soybean meal).This is because reducing crude protein decreases the quantity of fermentable protein entering the large intestine,which lowers post weaning diarrhea.It also lowers the requirement for expensive specialty protein sources or other protein sources such as soybean meal that present immunological challenges to the gut.The objective of this review is two-fold.The first is to discuss immunity by nutrition interactions,or lack thereof,and secondly,to review amino acid requirement estimates for nursery pigs. | Bob Goodband Mike Tokach Steve Dritz Joel DeRouchey Jason Woodworth | 2014 | Journal of Animal Science and Biotechnology2014,5,3: | 8 |
| 17 | Food legume production in China显示文摘Food legumes comprise all legumes grown for human food in China as either dry grains or vegetables,except for soybean and groundnut.China has a vast territory with complex ecological conditions.Rotation,intercropping,and mixed cropping involving pulses are normal cropping systems in China.Whether indigenous or introduced crops,pulses have played an important role in Chinese cropping systems and made an important contribution to food resources for humans since ancient times.The six major food legume species(pea,faba bean,common bean,mung bean,adzuki bean,and cowpea) are the most well-known pulses in China,as well as those with more local distributions;runner bean,lima bean,chickpea,lentil,grass pea,lupine,rice bean,black gram,hyacinth bean,pigeon pea,velvet bean,winged bean,guar bean,sword bean,and jack bean.China has remained the world's leading producer of peas,faba beans,mung beans,and adzuki beans in recent decades,as documented by FAO statistics and China Agriculture Statistical Reports.The demand for food legumes as a healthy food will markedly increase with the improvement of living standards in China.Since China officially joined the World Trade Organization(WTO) in2001,imports of pea from Canada and Australia have rapidly increased,resulting in reduced prices for dry pea and other food legumes.With reduced profits for food legume crops,their sowing area and total production has decreased within China.At the same time,the rising consumer demand for vegetable food legumes as a healthy food has led to attractive market prices and sharp production increases in China.Vegetable food legumes have reduced growing duration and enable flexibility in cropping systems.In the future,production of dry food legumes will range from stable to slowly decreasing,while production of vegetable food legumes will continue to increase. | Ling Li Tao Yang Rong Liu Bob Redden Fouad Maalouf Xuxiao Zong | 2017 | The Crop Journal2017,5,2: | 7 |

| 20 | The role of statins in both cognitive impairment and protection against dementia:a tale of two mechanisms显示文摘Nearly 30% of adults 40 years and older in the United States are on a statin.Their widespread use heightens the importance of careful consideration of their varied effects on the body.Although randomized controlled trials have not confirmed cognitive impairing effects with statins,continuing evidence suggests statins have the ability to cause reversible cognitive impairment in some patients.Paradoxically,statins have also been shown to decrease the risk of dementia,Alzheimer’s disease,and improve cognitive impairment in some cases.However,randomized controlled trials have similarly failed to find the beneficial effect.Supporting evidence for both claims is compelling whereas known limitations of the clinical trials may explain the lack of findings.This narrative review aims to explain why there is still controversy and how both effects can,and may,be possible.The mechanisms that have been hypothesized for each effect are seemingly independent from one another and may explain the contradicting results.Being mindful of the complex effects of statins,health care providers need to be able to identify patients who are at risk for or already experiencing cognitive impairment from statin use while also identifying those who could potentially decrease their risk of dementia with statins. | Bob G.Schultz Denise K.Patten Daniel J.Berlau | 2018 | Translational Neurodegeneration2018,7,1: | 6 |
