| 1 | 不同激光表面纹理对轴承材料AISI52100摩擦性能的影响显示文摘铬钢因具有高强度和耐磨性而用于轴承。然而,在实际使用中,因滑动摩擦导致的故障而使寿命缩短。为了提高AISI52100铬钢材料的耐久性,本文分析了激光表面纹理(LST)化的效果。利用圆盘摩擦,对不同形状,如椭圆和圆,与未纹理化处理试样的磨损行为进行了对比研究。用于磨损分析的润滑剂是SKFNLGI-3半固体锂基润滑脂。在10、30和50 N的不同载荷下,用750 r/min和1400 r/min 2种滑动速度进行滑动磨损分析。用扫描电子显微镜(SEM)对磨损形貌进行了分析。样品的粗糙度用白光干涉仪测量。与未纹理化处理试样相比,观察到不同形状如圆和椭圆对铬合金摩擦磨损性能的影响。由于磨损碎片和润滑剂被捕获,激光表面纹理显示椭圆的摩擦和磨损与圆形图案相比,明显减少。 | PAUL JOSHUA S DINESH BABU P | 2020 | Journal of Central South University2020，27，8： | 6 |
| 2 | Efficacy of pancreatoscopy for pancreatic duct stones:A systematic review and meta-analysis显示文摘BACKGROUND Pancreatic duct stones can lead to significant abdominal pain for patients.Per oral pancreatoscopy(POP)-guided intracorporal lithotripsy is being increasingly used for the management of main pancreatic duct calculi(PDC)in chronic pancreatitis.POP uses two techniques:Electrohydraulic lithotripsy(EHL)and laser lithotripsy(LL).Data on the safety and efficacy are limited for this procedure.We performed a systematic review and meta-analysis with a primary aim to calculate the pooled technical and clinical success rates of POP.The secondary aim was to assess pooled rates of technical success,clinical success for the two individual techniques,and adverse event rates.AIM To perform a systematic review and meta-analysis of POP,EHL and LL for management of PDC in chronic pancreatitis.METHODS We conducted a comprehensive search of multiple electronic databases and conference proceedings including PubMed,EMBASE,Cochrane,Google Scholar and Web of Science databases(from 1999 to October 2019)to identify studies with patient age greater than 17 and any gender that reported on outcomes of POP,EHL and LL.The primary outcome assessed involved the pooled technical success and clinical success rate of POP.The secondary outcome included the pooled technical success and clinical success rate for EHL and LL.We also assessed the pooled rate of adverse events for POP,EHL and LL including a subgroup analysis for the rate of adverse event subtypes for POP:Hemorrhage,post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP),perforation,abdominal pain,fever and infections.Technical success was defined as the rate of clearing pancreatic duct stones and clinical success as the improvement in pain.Randomeffects model was used for analysis.Heterogeneity between study-specific estimates was calculated using the Cochran Q statistical test and I2 statistics.Publication bias was ascertained,qualitatively by visual inspection of funnel plot and quantitatively by the Egger test.RESULTS A total of 16 studies including 383 patients met the inclusion criteria.The technical success rate of POP was 76.4%(95%CI:65.9-84.5;I2=64%)and clinical success rate was 76.8%(95%CI:65.2-85.4;I2=66%).The technical success rate of EHL was 70.3%(95%CI:57.8-80.3;I2=36%)and clinical success rate of EHL was 66.5%(95%CI:55.2-76.2;I2=19%).The technical success rate of LL was 89.3%(95%CI:70.5-96.7;I2=70%)and clinical success rate of LL was 88.2%(95%CI:66.4-96.6;I2=77%).The incidence of pooled adverse events for POP was 14.9%(95%CI:9.2-23.2;I2=49%),for EHL was 11.2%(95%CI:5.9-20.3;I2=15%)and for LL was 13.1%(95%CI:6.3-25.4;I2=31%).Subgroup analysis of adverse events showed rates of PEP at 7%(95%CI:3.5-13.6;I2=38%),fever at 3.7%(95%CI:2-6.9;I2=0),abdominal pain at 4.7%(95%CI:2.7-7.8;I2=0),perforation at 4.3%(95%CI:2.1-8.4;I2=0),hemorrhage at 3.4%(95%CI:1.7-6.6;I2=0)and no mortality.There was evidence of publication bias based on funnel plot analysis and Egger’s test.CONCLUSION Our study highlights the high technical and clinical success rates for POP,EHL and LL.POP-guided lithotripsy could be a viable option for management of chronic pancreatitis with PDC. | Syed M Saghir Harmeet S Mashiana Babu P Mohan Banreet S Dhindsa Amaninder Dhaliwal Saurabh Chandan Neil Bhogal Ishfaq Bhat Shailender Singh Douglas G Adler | 2020 | World Journal of Gastroenterology2020，26，34： | 5 |
| 3 | Anti-microbial principles of selected remedial plants from Southern India显示文摘Objective:To examine the anti-bacterial activity of leaf extracts of Morus alba L.(Moraceae)and Piper betel L.(Piperaceae),and seed extracts of Bombax ceiba L.(Borabacaceae).Methods:We have partially purified plant extracts by solvent extraction method,and evaluated the effect of individual fractions on bacterial growth using Escherichia coli(E.coli),Pseudomonas aeruginosa(P.aeruginosa) and Staphylococcus aureus(S.aureus) bacterial strains.Results:Compared with Morus and Bombax fractions,Piper fractions showed significant growth inhibition on all the three types of bacteria studied.The EtOAc-hexane fractions of Piper leaves exhibited significant antibacterial activity with minimum inhibitory concentrations(MIC) of 50 μg/mL culture against both gram-positive and gram-negative bacteria.The EtOAc-fractions Ⅰ,Ⅱ,and Ⅳ inhibited bacterial colony formation on soft agar in addition to growth inhibition.A combination treatment of piper fractions with ampicillin resulted in significant growth inhibition in E.coli and P.aeruginosa,and combination with anticancer drug geldanamycin(2 μg/mL) showed selective growth inhibition against P.aeruginosa and S.aureus.Three major compounds,i.e.,eugenol,3-hexene-ol and stigmasterol,were primarily identified from Piper betel leaf extractions.Among the individual compounds,eugenol treatment showed improved growth inhibition compared with stigmasterol and 3-hexene-ol.Conclusions:We are reporting potential anti-bacterial compounds from Piper betel against both gram-positive and gram-negative bacteria either alone or in combination with drug treatment. | Tirupathi Rao G Suresh Babu K J Ujwal Kumar Sujana P A Veerabhadr Raoa Sreedhar AS | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，4： | 5 |
| 4 | 印度农业推广改革现状:战略重点和政策选择显示文摘独立以来,虽然印度农业推广经历了翻天覆地的变化,但是小农农民和其他弱势群体仍未参与到公共推广体系之中。许多组织性能问题妨碍了公共推广体系的效率和效果。这些问题包括人员的匮乏,较低的合作伙伴关系以及继续自上而下的线性推广方式。本文回顾了印度农业推广改革的现状,并基于比哈尔、喜马偕尔邦、马哈拉施特拉邦和泰米尔纳德邦等4个邦的实地调研,分析并进一步细化了当前的改革进程,在此基础上,提出了促进农业公共推广体系有序发展和运行的优先政策和战略选择。 | Suresh C Babu P K Joshi Claire J.Glendenning Kwadwo Asenso-Okyere Rasheed Sulaiman V 蔡彦虹(翻译) | 2017 | 世界农业2017，，7： | 2 |
