2FAIR Principles:Interpretations and Implementation Considerations显示文摘The FAIR principles have been widely cited,endorsed and adopted by a broad range of stakeholders since their publication in 2016.By intention,the 15 FAIR guiding principles do not dictate specific technological implementations,but provide guidance for improving Findability,Accessibility,Interoperability and Reusability of digital resources.This has likely contributed to the broad adoption of the FAIR principles,because individual stakeholder communities can implement their own FAIR solutions.However,it has also resulted in inconsistent interpretations that carry the risk of leading to incompatible implementations.Thus,while the FAIR principles are formulated on a high level and may be interpreted and implemented in different ways,for true interoperability we need to support convergence in implementation choices that are widely accessible and(re)-usable.We introduce the concept of FAIR implementation considerations to assist accelerated global participation and convergence towards accessible,robust,widespread and consistent FAIR implementations.Any self-identified stakeholder community may either choose to reuse solutions from existing implementations,or when they spot a gap,accept the challenge to create the needed solution,which,ideally,can be used again by other communities in the future.Here,we provide interpretations and implementation considerations(choices and challenges)for each FAIR principle.Annika Jacobsen Ricardo de Miranda Azevedo Nick Juty Dominique Batista Simon Coles Ronald Cornet Melanie Courtot Merce Crosas Michel Dumontier Chris T.Evelo Carole Goble Giancarlo Guizzardi Karsten Kryger Hansen Ali Hasnain Kristina Hettne Jaap Heringa Rob W.W.Hooft Melanie Imming Keith G.Jeffery Rajaram Kaliyaperumal Martijn GKersloot Christine R.Kirkpatrick Tobias Kuhn Ignasi Labastida Barbara Magagna PeterMcQuilton Natalie Meyers Annalisa Montesanti Mirjam van Reisen Philippe Rocca-Serra Robert Pergl Susanna-Assunta Sansone Luiz Olavo Bonino da Silva Santos Juliane Schneider George Strawn Mark Thompson Andra Waagmeester Tobias Weigel Mark D.Wilkinson Egon L.Willighagen Peter Wittenburg Marco Roos Barend Mons Erik Schultes 2020Data Intelligence2020,2,1:26
3Benefit of combination β-blocker and endoscopic treatment to prevent variceal rebleeding: A meta-analysis显示文摘AIM: To determine whether the association of β-blockers with endoscopic treatment is superior to endoscopic treatment alone for the secondary prophylaxis of oesophageal variceal bleeding. METHODS: Randomised controlled trials comparing sclerotherapy (SCL) with SCL plus β-blockers (BB) or banding ligation (BL) with BL plus BB were identif ied.Main outcomes were overall and 6, 12 and 24 mo rebleeding rates, as well as overall and 6, 12 and 24 mo mortality. Two statistical methods were used: Yusuf-Peto, and Der Simonian and Laird. Inter-trial heterogeneity was systematically taken into account. RESULTS: Seventeen randomised controlled trials were included, 14 with SCL and 3 with BL. Combination β-blocker and endoscopic treatment signif icantly reduced rebleeding rates at 6, 12 and 24 mo and overall [odds ratio (OR): 2.20, 95% conf idence interval (CI): 1.69-2.85, P<0.0001] compared to endoscopic treatment alone. Mortality at 24 mo was signif icantly lower for the combined treatment group (OR: 1.83, 95% CI:1.16-2.90, P= 0.009), as well as overall mortality (OR: 1.43, 95% CI:1.03-1.98, P= 0.03). CONCLUSION: Combination therapy should thus be recommended as the fi rst line treatment for secondary prophylaxis of oesophageal variceal bleeding.Natalie Funakoshi Frédérique Ségalas-Largey Yohan Duny Frédéric Oberti Jean-Christophe Valats Michael Bismuth Jean-Pierre Daurès Pierre Blanc 2010World Journal of Gastroenterology2010,16,47:24
4Upper-gastrointestinal bleeding secondary to peptic ulcer disease:Incidence and outcomes显示文摘AIM:To evaluate the incidence,surgery,mortality,and readmission of upper gastrointestinal bleeding(UGIB)secondary to peptic ulcer disease(PUD).METHODS:Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta,Canada from 2004 to 2010(n=7079)using the International Classification of Diseases Codes(ICD-10).A subset of the data was validated using endoscopy reports.Positive predictive value and sensitivity with 95%confidence intervals(CI)were calculated.Incidence of UGIB secondary to PUD was calculated.Logistic regression was used to evaluate surgery,in-hospital mortality,and 30-d readmission to hospital with recurrent UGIB secondary to PUD.Co-variants accounted for in our logistic regression model included:age,sex,area of residence(i.e.,urban vs rural),number of Charlson comorbidities,presence of perforated PUD,undergoing upper endoscopy,year of admission,and interventional radiological attempt at controlling bleeding.A subgroup analysis(n=6356)compared outcomes of patients with gastric ulcers to those with duodenal ulcers.Adjusted estimates are presented as odds ratios(OR)with95%CI.RESULTS:The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were85.2%(95%CI:80.2%-90.2%)and 77.1%(95%CI:69.1%-85.2%),respectively.The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per100000.Overall risk of surgery,in-hospital mortality,and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%,8.5%,and 4.7%,respectively.Interventional radiology to control bleeding was performed in 0.6%of patients and 76%of these patients avoided surgical intervention.Thirty-day readmission significantly increased from 3.1%in 2004 to 5.2%in 2010(OR=1.07;95%CI:1.01-1.14).Rural residents(OR rural vs urban:2.35;95%CI:1.83-3.01)and older individuals(OR≥65 vs<65:1.57;95%CI:1.21-2.04)were at higher odds of being readmitted to hospital.Patients with duodenal ulcers had higher odds of dying(OR=1.27;95%CI:1.05-1.53),requiring surgery(OR=1.73;95%CI:1.34-2.23),and being readmitted to hospital(OR=1.54;95%CI:1.19-1.99)when compared to gastric ulcers.CONCLUSION:UGIB secondary to PUD,particularly duodenal ulcers,was associated with significant morbidity and mortality.Early readmissions increased over time and occurred more commonly in rural areas.Samuel Quan Alexandra Frolkis Kaylee Milne Natalie Molodecky Hong Yang Elijah Dixon Chad G Ball Robert P Myers Subrata Ghosh Robert Hilsden Sander Veldhuyzen van Zanten Gilaad G Kaplan 2014World Journal of Gastroenterology2014,20,46:21
5Haploinsufficiency of A20 (HA20): updates on the genetics, phenotype, pathogenesis and treatment显示文摘Background A20,a protein encoded by the tumor necrosis factor alpha-induced protein 3 gene(TNFAIP3),plays a vital role in the negative regulation of inflammation and immunity.Loss-of-function mutation in TNFAIP3 leads to a new described autoinflammatory disease-haploinsufficiency of A20(HA20).Since HA20 was first described in 2016,a number of new cases have been described in this literature,however,the disease and its pathogenesis are poorly understood.This review seeks to improve clinical recognition of this disorder,and promote both earlier diagnosis and initiation of targeted therapies to improve patients’outcomes.Methods We reviewed 26 papers about A20 and HA20,and we summarized genetic variants and clinical manifestations of a total of 61 reported patients from 26 families identified to have a genetic diagnosis of germline pathogenic variants in TNFAIP3/A20.Additionally,we discussed the pathogenesis and treatment of HA20.Results A total of 24 pathogenic variants of A20 had been reported.There was significant clinical heterogeneity,even among those with the same variants in TNFA1P3.Prior to receiving a molecular diagnosis of HA20,patients had been diagnosed with Behcet's disease,rheumatoid arthritis,rheumatic fever,juvenile idiopathic arthritis,systemic lupus erythematosus,and even adult-onset Stills'disease.The patients with HA20 that presented with inflammatory signatures in NF-kB signaling were mostly responsive to treatment.Conclusions HA20 is a monogenic autoinflammatory disease with highly variable clinical manifestations.This extensive heterogeneity makes it difficult to set a clinical diagnostic criteria,and genetic sequencing is necessary for a definitive diagnosis of HA20.Mei-Ping Yu Xi-Sheng Xu Qing Zhou Natalie Deuitch Mei-Ping Lu 2020World Journal of Pediatrics2020,16,6:17
6精子DNA损伤的机制和临床应用显示文摘在男性配子各种不同的DNA异常中,DNA断裂最为常见,尤其是在不育症患者中。目前越来越多的研究表明,DNA断裂并不显著影响精子细胞的存活率、活动率、形态以及与卵细胞的结合能力。研究还证明,卵母细胞在一定程度上可以修复受损的DNA,其修复程度依赖于精子细胞DNA的损伤类型和卵母细胞的质量。因此,研究精子DNA断裂(SDF)在自然分娩或辅助生殖技术助孕中对胚胎发育、胚胎着床、妊娠结果、子代健康的影响变得非常重要。至今,针对SDF对生殖的影响的研究极少,且研究报道的结论很不一致。导致这种不一致的原因可能与检测SDF的手段不同、实验设计不同和精液标本选择标准不同有关。因此,目前还不能确定是否将SDF检测拽术砬用于受精评估和ART技术中。这表明,制定SDF检测技术的标准化方法势在必行,另外关于SDF对ART的影响有必要进行进一步的临床研究。Lara Tamburrino Sara Marchiani Margarita Montoya Francesco Elia Marino Ilaria Natali Marta Cambi Gianni Forti Elisabetta Baldi Monica Muratori 2012Asian Journal of Andrology2012,14,1:16
7Current role of minimally invasive approaches in the treatment of early gastric cancer显示文摘Despite declining incidence,gastric cancer remains one of the most common cancers worldwide.Early detection in population-based screening programs has increased the number of cases of early gastric cancer,representing approximately 50%of newly detected gastric cancer cases in Asian countries.Endoscopic mucosal resection and endoscopic submucosal dissection have become the preferred therapeutic techniques in Japan and Korea for the treatment of early gastric cancer patients with a very low risk of lymph node metastasis.Laparoscopic and robotic resections for early gastric cancer,including function-preserving resections,have propagated through advances in technology and surgeon experience.The aim of this paper is to discuss the recent advances in minimally invasive approaches in the treatment of early gastric cancer.Abraham El-Sedfy Savtaj S Brar Natalie G Coburn 2014World Journal of Gastroenterology2014,20,14:15

10Electroacupuncture alleviates stress-induced visceral hypersensitivity through an opioid system in rats显示文摘AIM:To investigate whether stress-induced visceral hypersensitivity could be alleviated by electroacupuncture(EA) and whether EA effect was mediated by endogenous opiates.METHODS:Six to nine week-old male SpragueDawley rats were used in this study.Visceral hypersensitivity was induced by a 9-d heterotypic intermittent stress(HIS) protocol composed of 3 randomly stressors,which included cold restraint stress at 4?℃ for 45 min,water avoidance stress for 60 min,and forced swimming stress for 20 min,in adult male rats.The extent of visceral hypersensitivity was quantified by electromyography or by abdominal withdrawal reflex(AWR) scores of colorectal distension at different distention pressures(20 mmHg,40 mmHg,60 mmHg and 80 mmHg).AWR scores either 0,1,2,3 or 4 were obtained by a blinded observer.EA or sham EA was performed at classical acupoint ST-36(Zu-San-Li) or BL-43(Gao-Huang) in both hindlimbs of rats for 30 min.Naloxone(NLX) or NLX methiodide(m-NLX) was administered intraperitoneally to HIS rats in some experiments.RESULTS:HIS rats displayed an increased sensitivity to colorectal distention,which started from 6 h(the first measurement),maintained for 24 h,and AWR scores returned to basal levels at 48 h and 7 d after HIS compared to pre-HIS baseline at different distention pressures.The AWR scores before HIS were 0.6 ± 0.2,1.3 ± 0.2,1.9 ± 0.2 and 2.3 ± 0.2 for 20 mmHg,40 mmHg,60 mmHg and 80 mmHg distention pressures,respectively.Six hours after termination of the last stressor,the AWR scores were 2.0 ± 0.1,2.5 ± 0.1,2.8 ± 0.2 and 3.5 ± 0.2 for 20 mmHg,40 mmHg,60 mmHg and 80 mmHg distention pressures,respectively.EA given at classical acupoint ST-36 in both hindlimbs for 30 min significantly attenuated the hypersensitive responses to colorectal distention in HIS rats compared with sham EA treatment [AWRs at 20 mmHg:2.0 ± 0.2 vs 0.7 ± 0.1,P = 4.23 711 E-4;AWRs at 40 mmHg:2.6 ± 0.2 vs 1.5 ± 0.2,P = 0.00 163;AWRs at 60 mmHg:3.1 ± 0.2 vs 1.9 ± 0.1,P = 0.003;AWRs at 80 mmHg:3.6 ± 0.1 vs 2.4 ± 0.2,P = 0.0023;electromyographic(EMG) at 20 mmHg:24 ± 4.7 vs 13.8 ± 3.5;EMG at 40 mmHg:60.2 ± 6.6 vs 30 ± 4.9,P = 0.00 523;EMG at 60 mmHg:83 ± 10 vs 39.8 ± 5.9,P = 0.00 029;EMG at 80 mmHg:94.3 ± 10.8 vs 49.6 ± 5.9,P = 0.00 021].In addition,EA at the acupuncture point BL-43 with same parameters did not alleviate visceral hypersensitivity in HIS rats.EA in healthy rats also did not have any effect on AWR scores to colorectal distention at distention pressuresof 20 and 40 mmHg.The EA-mediated analgesic effect was blocked by pretreatment with NLX in HIS rats [AWR scores pretreated with NLX vs normal saline(NS) were 2.0 vs 0.70 ± 0.20,2.80 ± 0.12 vs 1.50 ± 0.27,3 vs 2.00 ± 0.15 and 3.60 ± 0.18 vs 2.60 ± 0.18 for 20 mmHg,40 mmHg,60 mmHg and 80 mmHg;P = 0.0087,0.0104,0.0117 and 0.0188 for 20,40,60 and 80 mmHg,respectively].Furthermore,EA-mediated analgesic effect was completely reversed by administration of m-NLX,a peripherally restricted opioid antagonist(EMG pretreated with m-NLX vs NS were 30.84 ± 4.39 vs 13.33 ± 3.88,74.16 ± 9.04 vs 36.28 ± 8.01,96.45 ± 11.80 vs 50.19 ± 8.28,and 111.59 ± 13.79 vs 56.42 ± 8.43 for 20 mmHg,40 mmHg,60 mmHg and 80 mmHg;P = 0.05 026,0.00 034,0.00 005,0.000 007 for 20 mmHg,40 mmHg,60 mmHg and 80 mmHg,respectively).CONCLUSION:EA given at classical acupoint ST-36 alleviates stress-induced visceral pain,which is most likely mediated by opioid pathways in the periphery.Yuan-Yuan Zhou Natalie J Wanner Ying Xiao Xuan-Zheng Shi Xing-Hong Jiang Jian-Guo Gu Guang-Yin Xu 2012World Journal of Gastroenterology2012,18,48:12

12Cassava:Nutrient composition and nutritive value in poultry diets显示文摘Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is,however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid(HCN). With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets.Natalie K.Morgan Mingan Choct 2016Animal Nutrition2016,,4:11
13人HCN4通道的滞后现象:影响窦房结起搏的潜在决定因素(英文)显示文摘超极化活化环核苷酸门控(hyperpolarization-activated cyclic-nucleotide-gated,HCN)通道参与调制心脏跳动的节律和速率。与HCN1和HCN2有所不同,慢通道HCN4可能不存在电压依赖的滞后现象。本研究采用单细胞膜片钳方法,在稳定转染hHCN4的HEK293细胞上进行电生理记录,观察hHCN4通道是否存在滞后现象,以及cAMP对其的调制作用;同时采用实时定量RT-PCR方法检测窦房结和心房组织中HCNs的表达。电压钳实验结果显示hHCN4电流(Ih)激活随着保持电位超极化的变化而向去极化方向移动。三角电位变化钳(triangular ramp)和动作电位钳的结果也显示了hHCN4的滞后现象。cAMP增加Ih电流幅度,且使电流激活向去极化方向移动,从而改变内源性hHCN4滞后行为。RT-PCR结果显示,人窦房结组织主要表达HCN4,占75%,HCN1占21%,HCN2占3%,HCN3占0.7%。以上结果提示,人窦房结组织主要表达HCN4亚型,hHCN4的Ih存在电压依赖性的滞后现象,且受cAMP调制。由此推断,hHCN4通道的滞后现象可能在窦房结起搏活动中起到了关键作用。萧永福 Natalie Chandler Halina Dobrzynski Eric S.Richardson Erica M.TenBroek Joshua J.Wilhelm Vinod Sharma Anthony Varghese Mark R.Boyett Paul A.Iaizzo Daniel C.Sigg 2010生理学报2010,62,1:10
14B7-H7 (HHLA2) inhibits T-cell activation and proliferation in the presence of TCR and CD28 signaling显示文摘Modulation of T-cell responses has played a key role in treating cancers and autoimmune diseases.Therefore,understanding how different receptors on T cells impact functional outcomes is crucial.The influence of B7-H7(HHLA2)and CD28H(TMIGD2)on T-cell activation remains controversial.Here we examined global transcriptomic changes in human T cells induced by B7-H7.Stimulation through TCR with OKT3 and B7-H7 resulted in modest fold changes in the expression of select genes;however,these fold changes were significantly lower than those induced by OKT3 and B7-1 stimulation.The transcriptional changes induced by OKT3 and B7-H7 were insufficient to provide functional stimulation as measured by evaluating T-cell proliferation and cytokine production.Interestingly,B7-H7 was coinhibitory when simultaneously combined with TCR and CD28 stimulation.This inhibitory activity was comparable to that observed with PD-L1.Finally,in physiological assays using T cells and APCs,blockade of B7-H7 enhanced T-cell activation and proliferation,demonstrating that this ligand acts as a break signal.Our work defines that the transcriptomic changes induced by B7-H7 are insufficient to support full costimulation with TCR signaling and,instead,B7-H7 inhibits T-cell activation and proliferation in the presence of TCR and CD28 signaling.Sadiye Amcaoglu Rieder Jingya Wang Natalie White Ariful Qadri Catherine Menard Geoffrey Stephens Jodi LKarnell Christopher ERudd Roland Kolbeck 2021Cellular & Molecular Immunology2021,18,6:9
15Effect of arabinoxylo-oligosaccharides and arabinoxylans on net energy and nutrient utilization in broilers显示文摘Arabinoxylo-oligosaccharides(AXOS) are hydrolytic degradation products of arabinoxylans(AX) that can be fermented by the gut microbiota, thus potentially displaying prebiotic properties. This study examined the effects of AX and AXOS on net energy(NE) and nutrient utilization in broilers. Ross 308 broilers(n = 90, 30 birds per treatment) were fed wheat-soybean diets supplemented with pure AX, AXOS produced by exposing the AX to xylanase in vitro(AXOS), or AX with xylanase(AX + E) from d 10 to 21.Performance parameters were measured from d 10 to 21. On d 15, 10 birds per treatment were allocated to closed-circuit net energy chambers to assess the impact of AX and AXOS on dietary energy utilization,through assessment of both metabolisable energy(ME) and NE. Ileal and caecal digesta samples were collected on d 21 to determine the effect of AX and AXOS on ileal and total tract dry matter digestibility,ileal digestible energy, digesta pH, short chain fatty acids(SCFA) and microbiota concentration. Feed conversion ratio was numerically the lowest in birds fed the diet supplemented with AXOS, which is 1.26 compared to 1.37 and 1.30 for AX and AX + E, respectively. Ileal dry matter digestibility was higher in birds fed AXOS than those fed AX(P = 0.047). Ileal digestible energy and total tract dry matter digestibility were higher in birds fed AXOS than those fed AX or AX + E(P = 0.004 and P = 0.001,respectively). Birds fed AXOS had higher ME intake(P = 0.049) and nitrogen retention(P = 0.001) and a strong trend of higher NE(P = 0.056), NE intake(P = 0.057) and retained energy(P = 0.054) compared to those fed AX. Ileal total SCFA, lactic and formic acid concentrations were higher in birds fed AXOS than those fed AX(P = 0.011, P = 0.012 and P = 0.023, respectively). Birds fed AXOS or AX + E had higher caecal total SCFA, acetic, butyric and isovaleric acid concentrations compared to those fed AX(P = 0.001,P = 0.004, P = 0.016 and P = 0.008, respectively), and caecal propionic acid concentration was higher in birds fed AX + E than those fed AX(P = 0.050). Ileal and caecal microbiota concentrations were numerically higher and pH was lower in birds fed AXOS and AX + E than those fed AX. Results from this study indicate that feeding AXOS directly is more efficient than AXOS generation in the gastrointestinal tract, and suggest that AXOS has a potential to be an efficacious prebiotic in broiler diets.Natalie K.Morgan Chake Keerqin Andrew Wallace Shu-Biao Wu Mingan Choct 2019Animal Nutrition2019,,1:8

19Galvanically induced potentials to enable minimal tribochemical wear of stainless steel lubricated with sodium chloride and ionic liquid aqueous solution显示文摘The effect of galvanically induced potentials on the friction and wear behavior of a 1 RK91 stainless steel regarding to tribocorrosion was investigated using an oscillating ball-on-disk tribometer equipped with an electrochemical cell. The aim of this investigation is to develop a water-based lubricant. Therefore 1 molar sodium chloride(NaCl) and 1% 1-ethyl-3-methylimidazolium chloride [C_2 mim][Cl] water solutions were used. Tribological performance at two galvanically induced potentials was compared with the non-polarized state: cathodic potential-coupling with pure aluminum- and anodic potential-coupling with pure copper. Frictional and electrochemical response was recorded during the tests. In addition, wear morphology and chemical composition of the steel were analyzed using scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS), respectively. The galvanically induced cathodic polarization of the stainless steel surface results in electrochemical corrosion protection and the formation of a tribolayer. Cations from the electrolyte(sodium Na^+ and 1-ethyl- 3-methylimidazolium [C_2 mim]^+) interact and adhere on the surface. These chemical interactions lead to considerably reduced wear using 1 NaC l(86%) and 1% 1-ethyl-3-methylimidazolium chloride [C_2 mim][Cl](74%) compared to the nonpolarized system. In addition, mechanical and corrosive part of wear was identified using this electrochemical technique. Therefore this method describes a promising method to develop water-based lubricants for technical applications.Tobias AMANN Felix GATTI Natalie OBERLE Andreas KAILER Jürgen RüHE 2018Friction2018,6,2:7
