1Corrosion Protection Properties of Organofunctional Silanes ——An Overview显示文摘The aim of this paper is to review the development and state of the art in the application of cer- tain organosilicon compounds known as trialkoxysilanes (or simply silanes) to the problems of the metal finishing industry. The ultimate goal of this work is the replacement of chromate passivation and paint pretreatments, as well as overcoming the shortcomings of organic coatings formulated in the modern environmentally friendly world, thus without chromate or chromated pigments, volatile organic carbon (VOC) containing compounds or harazardous air pollutants (HAPs).W.

2Influences of trans-trans farnesol,a membrane-targeting sesquiterpenoid,on Streptococcus mutans physiology and survival within mixed-species oral biofilms显示文摘Trans-trans farnesol (tt-farnesol) is a bioactive sesquiterpene alcohol commonly found in propolis (a beehive product) and citrus fruits, which disrupts the ability of Streptococcus mutans (S. mutans) to form virulent biofilms. In this study, we investigated whether tt-farnesol affects cell-membrane function, acid production and/or acid tolerance by planktonic cells and biofilms of S. mutans UA159. Furthermore, the influence of the agent on S. mutans gene expression and ability to form biofilms in the presence of other oral bacteria (Streptococcus oralis (S. oralis) 35037 and Actinomyces naeslundii (A. naeslundii) 12104) was also examined. In general, tt-farnesol (1 mmol·L-1) significantly increased the membrane proton permeability and reduced glycolytic activity of S. mutans in the planktonic state and in biofilms (P<0.05). Moreover, topical applications of 1 mmol·L-1 tt-farnesol twice daily (1 min exposure/treatment) reduced biomass accumulation and prevented ecological shifts towards S. mutans dominance within mixed-species biofilms after introduction of 1% sucrose. S. oralis (a non-cariogenic organism) became the major species after treatments with tt-farnesol, whereas vehicle-treated biofilms contained mostly S. mutans (>90% of total bacterial population). However, the agent did not affect significantly the expression of S. mutans genes involved in acidogenicity, acid tolerance or polysaccharide synthesis in the treated biofilms. Our data indicate that tt-farnesol may affect the competitiveness of S. mutans in a mixed-species environment by primarily disrupting the membrane function and physiology of this bacterium. This naturally occurring terpenoid could be a potentially useful adjunctive agent to the current anti-biofilm/anti-caries chemotherapeutic strategies.Jae-Gyu Jeon Santosh Pandit Jin Xiao Stacy Gregoire Megan L.

3Worldwide spread of the Ponseti method for clubfoot显示文摘The Ponseti method has become the gold standard for the treatment of idiopathic clubfoot. Its safety and efficacy has been demonstrated extensively in the literature, leading to increased use around the world over the last two decades. This has been demonstrated by the increase in Ponseti related Pub Med publications from many countries. We found evidence of Ponseti activity in 113 of 193 United Nations members. The contribution of many organizations which provide resources to healthcare practitioners in low and middle income countries, as well as Ponseti champions and modern communication technology, have helped to spread the Ponseti method around the world. Despite this, there are many countries where the Ponseti method is not being used, as well as many large countries in which the extent of activity is unknown. With its low rate of complication, low cost, and high effectiveness,this method has unlimited potential to treat clubfoot in both developed and undeveloped countries. Our listing of countries who have not yet shown presence of Ponseti activity will help non-governmental organizations to target those countries which still need the most help.Lior Shabtai Stacy C Specht John E Herzenberg 2014World Journal of Orthopedics2014,5,5:7
4华蟾素注射液治疗中晚期原发性肝癌的统评价和Meta分析(英文)显示文摘华蟾素是一种从蟾蜍中提取的化合物,是一种传统的中草药,已被证实在癌症治疗中具有疗效。华蟾素注射液广泛应用于中国中晚期肝癌患者。本研究的目的是明确华蟾素注射液对这类特定患者的影响。在PubMed,EMBASE,CENTRAL和其他四个主要的中国数据库中检索使用华蟾素注射液治疗中晚期肝癌随机对照试验。根据Cochrane协作和RevMan 5.3的建议进行系统评价和Meta-分析。根据Cochrane手册计算风险比(RR)和相应的95%置信区间,使用随机效应模型来统计数据。最后共纳入了11项随机对照试验,728名患者。所有试验均显示,使用华蟾素注射干预组的总反应率,Karnofsky表现评分(KPS)的总反应率,1–2年生存率和生活质量均有明显改善。但是6个月生存率和临床受益率各组之间没有统计学差异。本研究发现华蟾素注射液对中晚期肝癌患者的总反应率和1至2年生存率的有益作用。因此我们认为华蟾素注射液治疗中晚期肝癌的疗效可能优于对照组。鉴于大多数试验质量较低,因此需要严格按照CONSORT for TCM设计的更高质量的前瞻性随机试验来进一步验证。董志勇 邱仙土 Stacy A.Kujawa S.M.Shariful Islam 张杰 2019Journal of Chinese Pharmaceutical Sciences2019,28,4:7
5Predictors of suboptimal bowel preparation in asymptomatic patients undergoing average-risk screening colonoscopy显示文摘AIM To identify risk factors for a suboptimal preparation among a population undergoing screening or surveillance colonoscopy.METHODS Retrospective review of the University of Michigan and Veteran's Administration(VA) Hospital records from 2009 to identify patients age 50 and older who underwent screening or surveillance procedure and had resection of polyps less than 1 cm in size and no more than 2 polyps. Patients with inflammatory bowel disease or a family history of colorectal cancer were excluded. Suboptimal procedures were defined as procedure preparations categorized as fair, poor or inadequate by the endoscopist. Multivariable logistic regression was used to identify predictors of suboptimal preparation.RESULTS Of 4427 colonoscopies reviewed, 2401 met our inclusion criteria and were analyzed. Of our population, 16% had a suboptimal preparation. African Americans were 70% more likely to have a suboptimal preparation(95%CI: 1.2-2.4). Univariable analysis revealed that narcotic and tricyclic antidepressants(TCA) use, diabetes, prep type, site(VA vs non-VA), and presence of a gastroenterology(GI) fellow were associated with suboptimal prep quality. In a multivariable model controlling for gender, age, ethnicity, procedure site and presence of a GI fellow, diabetes [odds ratio(OR) = 2.3; 95%CI: 1.6-3.2], TCA use(OR = 2.5; 95%CI: 1.3-4.9), narcotic use(OR = 1.7; 95%CI: 1.2-2.5) and Miralax-Gatorade prep vs 4L polyethylene glycol 3350(OR = 0.6; 95%CI: 0.4-0.9) were associated with a suboptimal prep quality. CONCLUSION Diabetes, narcotics use and TCA use were identified as predictors of poor preparation in screening colonoscopies while Miralax-Gatorade preps were associated with better bowel preparation.Shail M Govani Eric E Elliott Stacy B Menees Stephanie L Judd Sameer D Saini Constantinos P Anastassiades Annette L Urganus Suzanna J Boyce Philip S Schoenfeld 2016World Journal of Gastrointestinal Endoscopy2016,8,17:7

7Adaptive introductions:How multiple experiments and comparisons to wild populations provide insights into requirements for long-term introduction success of an endangered shrub显示文摘Recovery of an imperiled plant species may require augmentation of existing populations or creation of new ones.Hundreds of such projects have been conducted over the last few decades,but there is a bias in the literature favoring successes over failures.In this paper,we evaluate a series of introductions that experimentally manipulated microhabitat and fire in an adaptive introduction framework.Between 2002 and 2012,we(and our collaborators) carried out ten introductions and augmentations of Florida ziziphus Pseudoziziphus(Condalia,Ziziphus) celata,a clonal shrub limited to very small populations and narrowly endemic to pyrogenic central Florida sandhills.Six of the introductions were designed as experiments to test hypotheses about how demographic performance was affected by microhabitat,fire,and propagule type.Introduced transplants had high survival(<90%annually),inconsistent growth,and little transition to reproduction,while introduced seeds had low germination and survival.Transplants were more efficient than seeds as translocation propagules.Shaded(vs.open) sites supported generally higher transplant and seedling survival and seed germination percentages,but growth responses varied among experiments.Supplemental irrigation increased transplant survival and seed germination,but otherwise seedling and plant survival and growth were not significantly affected.Contrary to expectations based on wild populations,introduced propagules have not been more successful in unshaded sites,suggesting that Florida ziziphus has broader microhabitat preferences than hypothesized.Compared to wild plants,introduced plants had similar survival and responses to fire,slower growth,and more delayed flowering.Introduced plants had no clonal spread.While no introduced population has demonstrated a capacity for long-term viability,one augmented population has flowered and produced viable fruits.Given that Florida ziziphus genets are long-lived,low levels of sexual reproduction may be adequate for the establishment of viable populations.Thus,after many translocations over more than a decade,it is premature to characterize any single translocation as a success or a failure,underscoring the need for a long view of translocation success.Eric S.Menges Stacy A.Smith Carl W.Weekley 2016Plant Diversity2016,38,5:4

10Split-dose bowel preparation improves adequacy of bowel preparation and gastroenterologists' adherence to National Colorectal Cancer Screening and Surveillance Guidelines显示文摘AIM To quantify the impact of split-dose regimen on endoscopists' compliance with guideline recommendations for timing of repeat colonoscopy in patients with normal colonoscopy or 1-2 small polyps(< 10 mm).METHODS A retrospective chart review of all endoscopy reports was undertaken in average-risk individuals > 50 years old with a normal screening colonoscopy and 1-2 small polyps. Data were abstracted from two time periods, pre and post-split-dose bowel preparation institution. Main outcome measurements were recommendation for timing of repeat colonoscopy and bowel preparation quality. Bivariate analysis by χ~2 tests and Student's t-tests were performed to assess differences between the two cohorts. Multivariable logistic regression was used with guideline consistent recommendations as the dependent variables and an indicator for 2011 cohort as the primary predictor. RESULTS Four thousand two hundred and twenty-five patients were included in the study; 47.0%(1987) prior to the institution of split dose bowel preparation, and 53.0%(2238) after the institution of split dose bowel preparation. Overall, 82.2%(n = 3472) of the colonoscopies were compliant with guideline recommendations, with a small but significantly increased compliance rate in year 2011(83.7%) compared to year 2009(80.4%, P = 0.005), corresponding to an unadjusted odds ratio of 1.25(95%CI: 1.07-1.47; P = 0.005). Colonoscopies with either 'Adequate' or 'Excellent' had increased from 30.6% in year 2009 to 39.6% in year 2011(P < 0.001). However, there was no significant difference in poor/inadequate category of bowel preparation as there was a mild increase from 4.6% in year 2009 to 5.1% in year 2011(P = 0.50). CONCLUSION Split-dose bowel regimen increases endoscopists' compliance to guidelines in average-risk patients with normal colonoscopy or 1-2 small polyps.Stacy Bartnik Menees H Myra Kim Philip Schoenfeld 2018World Journal of Gastroenterology2018,24,6:4
11轻度缺乏磷的日粮中随着钙和有效磷比值增加对保育猪生长性能和骨骼发育的不利影响显示文摘文章旨在评估在含植酸酶日粮中(250 FTU/kg)增加钙(Ca)和有效磷(aP)比例对保育猪生长性能和骨骼矿物质含量(骨密度,BMC)的影响。试验将480头保育猪(体重BW=5.7±0.6 kg)随机分配为7个处理,Ca∶aP递增分别为:1.25∶1、1.50∶1、1.75∶1、2.00∶1、2.25∶1、2.50∶1、2.75∶1,每个处理7个重复(其中6个重复饲喂2.75∶1日粮),每个重复10头猪。从试验正式开始前7 d至第0天,所有仔猪饲喂相同日粮。试验期分为两个阶段(阶段1和阶段2),分别为1—14 d和15—28 d,试验猪只在试验期饲喂处理日粮。阶段1和阶段2日粮配方中有效磷比例分别为0.33%和0.27%(大约为需要量的90%)。测定体重(BW)、平均日增重(ADG)、平均日采食量(ADFI)和体重与饲料比(G∶F)。试验第28天使用双X射线骨密度仪测定每头猪肱骨的BMC。数据采用PROC MIXED(SAS 9.3)线性混合模型分析。利用正交多项式对比计算Ca∶aP递增的线性和二次效应。整个28 d试验期,Ca∶aP递增导致ADG(353、338、328、304、317、291和280 g/d;P<0.01)、ADFI(539、528、528、500、533、512和489 g/d;P<0.05)和G∶F(0.68、0.66、0.64、0.62、0.61、0.59和0.58;P<0.01)呈线性递减。Ca∶aP递增也会导致第14天和第28天BW降低(P<0.01)。肱骨的BMC随着Ca∶aP递增而减少(6.2、6.3、5.7、5.9、5.5、5.6和5.3 g;P<0.01)。下面是Ca∶aP对各指标的回归分析影响,其中X是Ca∶aP:ADG[g/d]=339-36x,r^2=0.81;G:F=0.61-0.03x,r^2=0.72;BMC[g]=6.4-0.27x,r^2=0.43。所有结果表明,任何高于这次试验中所使用的最低Ca∶aP的钙水平日粮均会损害动物生长性能和骨骼发育。有必要进一步研究日粮中更低水平钙含量。何颖(编译) Spenser L.Becker Stacie A.Gould Amy L.Petry Leah M.Kellesvig John.F.Patience 2020猪业科学2020,37,12:3

15A survey of ampullectomy practices显示文摘AIM:To investigate the endoscopic ampullectomy practices of expert biliary endoscopists.METHODS:An anonymous survey was mailed to 79 expert biliary endoscopists to assess ampullectomy practices.RESULTS:Forty six(58%) biliary endoscopists returned the questionnaire.Of these, 63% were in academia and in practice for an average of 16.4 years(± 8.6).Endoscopists performed an average of 1.1(± 0.8) ampullectomies per month.Prior to ampullectomy, endoscopic ultrasound was'always'utilized by 67% of respondents vs'sometimes'in 31% of respondents.Empiric biliary sphincterotomy was not utilized uniformly, only 26%'always'and 37%'sometimes'performed it prior to resection.Fifty three percent reported'never'performing empiric pancreatic sphincterotomy prior to ampullectomy.Practitioners with high endoscopic retrograde cholangiopancreatography volumes were the most likely to perform a pancreatic sphincterotomy(OR = 10.9;P = 0.09).Participants overwhelmingly favored'always'placing a prophylactic pancreatic stent, with 86% placing it after ampullectomy rather than prior to resection(23%).Argon plasma coagulation was the favored adjunct modality(83%) for removal of residual adenomatous tissue.Practitioners uniformly(100%) preferred follow-up examination to be within 6 mo post-ampullectomy.CONCLUSION:Among biliary experts, there is less variation in ampullectomy practices than is reflected in the literature.Stacy B Menees Philip Schoenfeld Hyungjin Myra Kim Grace H Elta 2009World Journal of Gastroenterology2009,15,28:2
16过度诊断、伦理学和电车难题显示文摘在英国、美国、加拿大及其他一些地方对乳房X光检查一直存在争议,对前列腺癌、慢性肾病、注意缺陷多动障碍(ADHD)以及其他许多状况的过度诊断也存在争议。人们迫不得已选择担心过度诊断,是由于有证据证明其危害大于受益。不过,并非人人都同样认为这是迫不得已的选择。这也可能是因为对证据、利益冲突方面存在分歧,或由于认知偏差。造成分歧的另一个可能原因是,有些人可能并不认为受益和伤害是最重要的考虑因素。这种比较是伦理规范的核心。从广义上讲,功利主义伦理学家认为,假设有几种选择,我们应该选择在计算中确保每个人同等重要时,能产生总体结果最佳的选项。非后果论伦理学家则认为,其他伦理学问题,如权利、义务或尊重人的尊严或自主性,是更重要的。Stacy M Carte 翟晓梅(译) 2019中国医院院长2019,0,10:2
17日粮中添加过瘤胃保护B族维生素对奶牛健康、产奶量和繁殖性能的影响显示文摘围产期日粮中添加过瘤胃保护B族维生素对奶牛健康、产奶量和繁殖性能都会产生影响。试验结果表明,添加过瘤胃保护B族维生素可以显著降低刚分娩奶牛亚临床酮病的发病率、奶牛平均人工授精成本以及泌乳190天内的淘汰率(P<0.05);显著增加乳脂率和泌乳150天怀孕率(P<0.05);胎衣不下的发病率从18.5%减少到16.0%,但是差异不显著。这说明在围产期日粮中添加过瘤胃保护B族维生素可以提高牛奶乳脂率、奶牛健康状况以及繁殖性能,并能为奶牛场节省成本,提高经济效益。Essi Evan Helene Leclerc Stacy Wrinkle 詹小立 阳成波 2015中国乳业2015,,8:2
183D additive manufactured composite scaffolds with antibiotic-loaded lamellar fillers for bone infection prevention and tissue regeneration显示文摘Bone infections following open bone fracture or implant surgery remain a challenge in the orthopedics field.In order to avoid high doses of systemic drug administration,optimized local antibiotic release from scaffolds is required.3D additive manufactured(AM)scaffolds made with biodegradable polymers are ideal to support bone healing in non-union scenarios and can be given antimicrobial properties by the incorporation of antibiotics.In this study,ciprofloxacin and gentamicin intercalated in the interlamellar spaces of magnesium aluminum layered double hydroxides(MgAl)andα-zirconium phosphates(ZrP),respectively,are dispersed within a thermoplastic polymer by melt compounding and subsequently processed via high temperature melt extrusion AM(~190◦C)into 3D scaffolds.The inorganic fillers enable a sustained antibiotics release through the polymer matrix,controlled by antibiotics counterions exchange or pH conditions.Importantly,both antibiotics retain their functionality after the manufacturing process at high temperatures,as verified by their activity against both Gram+and Gram-bacterial strains.Moreover,scaffolds loaded with filler-antibiotic do not impair human mesenchymal stromal cells osteogenic differentiation,allowing matrix mineralization and the expression of relevant osteogenic markers.Overall,these results suggest the possibility of fabricating dual functionality 3D scaffolds via high temperature melt extrusion for bone regeneration and infection prevention.María C´amara-Torres Stacy Duarte Ravi Sinha Ainhoa Egizabal Noelia´Alvarez Maria Bastianini Michele Sisani Paolo Scopece Marco Scatto Alessandro Bonetto Antonio Marcomini Alberto Sanchez Alessandro Patelli Carlos Mota Lorenzo Moroni 2021Bioactive Materials2021,6,4:2
