1高血压患者脑小血管病变化对认知功能的影响显示文摘高血压是脑小血管病进展与认知功能障碍的主要危险因素之一。该研究旨在探讨高血压患者脑小血管病损伤变化与认知功能减退及轻度认知功能障碍的关系。该研究的数据从ISSYS队列(探讨高血压无症状性脑卒中:一个磁共振成像研究)中获得,其是一项纵向人群研究,纳入基线无痴呆及脑卒中,年龄50~70岁的高血压患者。Jiménez-Balado J Riba-Llena I Abril O Garde E Penalba A Ostos E Maisterra O Montaner J Noviembre M Mundet X Ventura O Pizarro J Delgado P 赵狄 练桂丽 2019中华高血压杂志2019,27,2:15
2石灰石的煅烧分解及其吸收二氧化碳机理显示文摘在天然气或合成气制氢过程中,借助于石灰石煅烧分解与石灰吸收二氧化碳的化学循环反应,去除反应产物,破坏化学平衡,可以连续地驱动化学反应进行,从而提高氢气的产率,同时控制温室气体二氧化碳的排放.在多功能热重反应器(TGR)内就化学循环反应过程中的颗粒尺寸、温度煅烧分解率等对吸附剂煅烧分解和吸收特性的影响进行了比较充分的实验研究.当吸收反应温度在500℃~620℃范围内时,CaO吸收二氧化碳的反应速率与石灰石中钙的利用率都维持在比较高的水平,石灰石分解后产生的氧化钙的利用率增长比石灰石的分解率增长慢,分解率高,吸热量也高,因此,简单地提高石灰石的分解率并不是提高石灰石钙利用率的最佳选择。阎常峰 陈勇 李小森 Grace J R Jim Lim 2006煤炭转化2006,29,2:7
3Diagnostic and therapeutic challenges of gastrointestinal angiodysplasias: A critical review and view points显示文摘Gastrointestinal angiodysplasias (GIADs), also called angioectasias, are the most frequent vascular lesions. Its precise prevalence is unknown since most of them are asymptomatic. However, the incidence may be increasing since GIADs affect individuals aged more than 60 years and population life expectancy is globally increasing worldwide. They are responsible of about 5% to 10% of all gastrointestinal bleeding (GIB) cases. Most GIADs are placed in small bowel, where are the cause of 50 to 60% of obscure GIB diagnosed with video capsule endoscopy. They may be the cause of fatal severe bleeding episodes;nevertheless, recurrent overt or occult bleeding episodes requiring repeated expensive treatments and disturbing patient’s quality-of-life are more frequently observed. Diagnosis and treatment of GIADs (particularly those placed in small bowel) are a great challenge due to insidious disease behavior, inaccessibility to affected sites and limitations of available diagnostic procedures. Hemorrhagic causality out of the actively bleeding lesions detected by diagnostic procedures may be difficult to establish. No treatment guidelines are currently available, so there is a high variability in the management of these patients. In this review, the epidemiology and pathophysiology of GIADs and the status in the diagnosis and treatment, with special emphasis on small bowel angiodysplasias based on multiple publications, are critically discussed. In addition, a classification of GIADs based on their endoscopic characteristics is proposed. Finally, some aspects that need to be clarified in future research studies are highlighted.Diego García-Compeán ángel N Del Cueto-Aguilera Alan R Jiménez-Rodríguez José A González-González Héctor J Maldonado-Garza 2019World Journal of Gastroenterology2019,25,21:5
4Risk factors for Barrett’s oesophagus and oesophageal adenocarcinoma:Results from the FINBAR study显示文摘AIM:To investigate risk factors associated with Barrett's oesophagus and oesophageal adenocarcinoma.METHODS:This all-Ireland population-based case-control study recruited 224 Barrett's oesophagus patients,227 oesophageal adenocarcinoma patients and 260 controls.All participants underwent a structured interview with information obtained about potential lifestyle and environmental risk factors.RESULTS:Gastro-oesophageal reflux was associated with Barrett's [OR 12.0(95% CI 7.64-18.7)] and oesophageal adenocarcinoma [OR 3.48(95% CI 2.25-5.41)].Oesophageal adenocarcinoma patients were more likely than controls to be ex-or current smokers [OR 1.72(95% CI 1.06-2.81)and OR 4.84(95% CI 2.72-8.61)respectively] and to have a high body mass index [OR 2.69(95% CI 1.62-4.46)].No significant associations were observed between these risk factors and Barrett's oesophagus.Fruit but not vegetables were negatively associated with oesophageal adenocarcinoma [OR 0.50(95% CI 0.30-0.86)].CONCLUSION:A high body mass index,a diet low in fruit and cigarette smoking may be involved in the progression from Barrett's oesophagus to oesophageal adenocarcinoma.Lesley A Anderson RG Peter Watson Seamus J Murphy Brian T Johnston Harry Comber Jim Mc Guigan John V Reynolds Liam J Murray 2007World Journal of Gastroenterology2007,13,10:5
5Effects 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 Pea Jiménez Alberto B Pliego Juan C V Chagoyán María A Cerrillo Miguel A Rodríguez 2015Journal of Integrative Agriculture2015,14,1:4
6金属氧化物纳米颗粒对磷的吸附及回收潜力显示文摘比较4种金属氧化物纳米颗粒(nMgO,nAl_2O_3,nTiO2和nFe_2O_3)对水体P的吸附性能,并探讨了pH、吸附时间、共存离子等因素对nMgO吸附P的影响,用XRD和XPS分析了nMgO对P的吸附机制,最后通过小青菜盆栽实验法探讨nMgO从养殖废水中吸附回收P的应用潜力.结果发现,在pH3.0~8.0范围内,nMgO对P的吸附量显著高于nAl_2O_3、nTiO_2和nFe_2O_3,4种纳米颗粒对P的吸附量分别可达40、31.77、15.93和13.08mg/g.吸附后P的解吸可逆性较差.nMgO对P的吸附能在0.5h内达到吸附平衡,P的吸附符合准二级动力学过程.体系共存的等量F^-、Cl^-、NO_3^-、SO_4^(2-)、Na^+、K^+和NH_4^+离子对nMgO吸附P无显著影响,Mg^(2+)和Ca^(2+)离子对P吸附具有促进作用.nMgO对P的吸附等温线可用Langmuir模型描述,最大吸附量达139.3mg/g.XRD和XPS分析表明,nMgO对P的吸附是伴有静电吸引的以表面络合沉淀反应为主的吸附过程.nMgO能有效地从养殖废水中吸附回收P,吸附P的nMgO作为肥料,能使小青菜干物质量从0.31g/kg土增加到0.96g/kg土.梁文 何维 李满林 黄辉 Wang Jim J 张增强 李荣华 2017中国环境科学2017,37,7:3
7Endoscopic and anesthetic feasibility of EUS and ERCP combined in a single session versus two different sessions显示文摘AIM:To discuss the feasibility of single session endoscopic ultrasonography(EUS) to discuss and endoscopic retrograde cholangiopancreatography(ERCP) execution.METHODS:Retrospective endoscopic and anesthetic outcome comparison of performing both EUS and ERCP in a single endoscopic session(Group Ⅰ) versus performing each procedure in two different sessions(Group Ⅱ) was made.The following variables were evaluated:epidemiological variables,American Society of Anesthesiologists Physical Status Classification(ASA) level,procedural time,propofol dose,anesthetic complications,endoscopic complications and diagnostic yield,and therapeutic procedures on both groups.T-student,ChiSquare and Fisher test were used for comparison.RESULTS:We included 39 patients in Group Ⅰ(mean age:69.85 ± 9.25;27 men) and 46 in Group Ⅱ(mean age:67.46 ± 12.57;25 men).Procedural time did not differ significantly between both groups(Group Ⅰvs Group Ⅱ:93 ± 32.78 vs 98.98 ± 38.17;P >0.05) but the dose of propofol differed(Group Ⅰ vs Group Ⅱ:322.28 ± 250.54 mg vs 516.96 ± 289.06 mg;P = 0.001).Three patients had normal findings on both explorations.Three anesthetic complications [O2 desaturation(2),broncoaspiration(1)] and 9 endoscopic complications [pancreatitis(6),bleeding(1),perforation(1),cholangitis(1)] occurred without significant differences between both groups(P > 0.05).We did not find any significant difference regarding age,sex,ASA scale level,diagnostic yield or therapeutic maneuvers between both groups.CONCLUSION:The performance of EUS and ERCP in a single session offers a similar diagnostic and therapeutic yield,does not entail a higher complication risk and requires a significantly smaller dose of propofol for sedation compared with performing each exploration in a different session.Juan J Vila Marcos Kutz Silvia Goi Miriam Ostiz Edurne Amorena Carlos Prieto Cristina Rodriguez Ignacio Fernández-Urien Francisco J Jiménez 2011World Journal of Gastrointestinal Endoscopy2011,3,3:3
8Mapping aboveground biomass by integrating geospatial and forest inventory data through a k-nearest neighbor strategy in North Central Mexico显示文摘As climate change negotiations progress,monitoring biomass and carbon stocks is becoming an important part of the current forest research.Therefore,national governments are interested in developing forest-monitoring strategies using geospatial technology.Among statistical methods for mapping biomass,there is a nonparametric approach called k-nearest neighbor(kNN).We compared four variations of distance metrics of the kNN for the spatially-explicit estimation of aboveground biomass in a portion of the Mexican north border of the intertropical zone.Satellite derived,climatic,and topographic predictor variables were combined with the Mexican National Forest Inventory(NFI)data to accomplish the purpose.Performance of distance metrics applied into the kNN algorithm was evaluated using a cross validation leave-one-out technique.The results indicate that the Most Similar Neighbor(MSN)approach maximizes the correlation between predictor and response variables(r=0.9).Our results are in agreement with those reported in the literature.These findings confirm the predictive potential of the MSN approach for mapping forest variables at pixel level under the policy of Reducing Emission from Deforestation and Forest Degradation(REDD+).Carlos A AGUIRRE-SALADO Eduardo J TREVIO-GARZA Oscar A AGUIRRE-CALDERóN Javier JIMNEZ-PREZ Marco A GONZLEZ-TAGLE José R VALDZ-LAZALDE Guillermo SNCHEZ-DíAZ Reija HAAPANEN Alejandro I AGUIRRE-SALADO Liliana MIRANDA-ARAGóN 2014Journal of Arid Land2014,6,1:3
9Is iron overload in alcohol-related cirrhosis mediated by hepcidin?显示文摘In this case report we describe the relationship between ferritin levels and hepcidin in a patient with alcohol-related spur cell anemia who underwent liver transplantation.We demonstrate a reciprocal relation-ship between serum or urinary hepcidin and serum ferritin,which indicates that inadequate hepcidin production by the diseased liver is associated with elevated serum ferritin.The ferritin level falls with increasing hepcidin production after transplantation.Neither inflammatory indices(IL6)nor erythropoietin appear to be related to hepcidin expression in this case.We suggest that inappropriately low hepcidin production by the cirrhotic liver may contribute substantially to elevated tissue iron stores in cirrhosis and speculate that hepcidin replacement in these patients may be of therapeutic benefi t in the future.Tariq Iqbal Azzam Diab Douglas G Ward Matthew J Brookes Chris Tselepis Jim Murray Elwyn Elias 2009World Journal of Gastroenterology2009,15,46:2
