2Operative link for gastritis assessment vs operative link on intestinal metaplasia assessment显示文摘AIM:To compare the reliability of gastritis staging sys-tems in ranking gastritis-associated cancer risk in a large series of consecutive patients.METHODS:Gastric mucosal atrophy is the precancer-ous condition in which intestinal-type gastric cancer(GC)most frequently develops.The operative link for gas-tritis assessment(OLGA)staging system ranks the GC risk according to both the topography and the severity of gastric atrophy(as assessed histologically on the ba-sis of the Sydney protocol for gastric mucosal biopsy).Both cross-sectional and long-term follow-up trials have consistently associated OLGA stages Ⅲ-Ⅳ with a higher risk of GC.A recently-proposed modification of the OLGA staging system(OLGIM)basically incorporates the OLGA frame,but replaces the atrophy score with an assessment of intestinal metaplasia(IM)alone.A series of 4552 consecutive biopsy sets(2007-2009)was re-trieved and reassessed according to both the OLGA and the OLGIM staging systems.A set of at least 5 biopsy samples was available for all the cases considered.RESULTS:In 4460 of 4552 cases(98.0%),both the high-risk stages(Ⅲ + Ⅳ)and the low-risk stages(0 +Ⅰ + Ⅱ)were assessed applying the OLGA and OL-GIM criteria.Among the 243 OLGA high-risk stages,14(5.8%)were down-staged to a low risk using OLGIM.The 67(1.5%)incidentally-found neoplastic lesions(intraepithelial or invasive)were consistently associated with high-risk stages,as assessed by both OLGA and OLGIM(P < 0.001 for both).Two of 34 intestinal-type GCs coexisting with a high-risk OLGA stage(stage Ⅲ)were associated with a low-risk OLGIM stage(stage Ⅱ).CONCLUSION:Gastritis staging systems(both OLGA and OLGIM)convey prognostically important informa-tion on the gastritis-associated cancer risk.Because of its clinical impact,the stage of gastritis should be included as a conclusive message in the gastritis histol-ogy report.Since it focuses on IM alone,OLGIM staging is less sensitive than OLGA staging in the identif ication of patients at high risk of gastric cancer.Massimo Rugge Matteo Fassan Marco Pizzi Fabio Farinati Giacomo Carlo Sturniolo Mario Plebani David Y Graham 2011World Journal of Gastroenterology2011,17,41:19
3乙二醛对蛋白基胶黏剂结构及性能的影响显示文摘选用2种典型蛋白原料大豆粉及谷蛋白粉,通过刨花板内结合强度性能测试及CP-MAS 13CNMR分析,对比乙二醛化蛋白基胶黏剂与甲醛化蛋白基胶黏剂的性能特征。结果表明,乙二醛与蛋白分子之间发生了化学反应,但由于其交联程度不及甲醛化蛋白胶黏剂,导致其胶接性能不及后者,若提高pMDI等交联剂的添加量,乙二醛化蛋白胶黏剂也可用于人造板制备。雷洪 杜官本 Pizzi A 周晓剑 2011西南林学院学报2011,31,2:17
4苯酚-尿素-甲醛共缩聚树脂结构形成比较显示文摘用13CNMR定量分析跟踪研究了两种不同合成路线中苯酚-尿素-甲醛共缩聚树脂(PUF)结构形成过程,比较了3种PUF树脂的结构构成。研究发现树脂制备过程中的酸性环境导致脲醛树脂初聚物含量增加以及尿素与苯酚之间的共缩聚增加;合成反应初期的介质环境对羟甲基酚的形成有着决定性的影响;合成过程中酸性环境所处阶段不同,最终树脂结构出现差异。雷洪 杜官本 PIZZI Antonio 李琴 赵伟刚 方群 2009林产化学与工业2009,29,1:12

6碱性环境下苯酚-尿素-甲醛共缩聚树脂结构形成研究显示文摘为了了解碱性环境中苯酚-尿素-甲醛(PUF)共缩聚树脂结构形成规律,为PUF树脂结构控制提供依据,使用13C NMR表征,采用分次加入苯酚、甲醛和尿素的技术路线,定量分析了PUF树脂合成过程中各种官能团的变化和聚合物分子链的构成。结果表明,碱性环境中各种加料方式合成的PUF树脂初聚物具有十分相近的化学结构,PUF树脂也具有十分相近的化学结构,但结构组分存在差异,在原料物质的量之比一定的条件下,最终反应进程基本接近。甲醛分次加入,减少了醚类的生成,有利于简化反应进程。初聚物的热机械性能分析表明不同加料方式对酚醛树脂固化性能无显著影响。雷洪 杜官本 PIZZI Antonio 赵伟刚 李琴 方群 赵超超 2009林产化学与工业2009,29,3:8
7PF和PUF树脂分子结构对比研究显示文摘为了判断苯酚-尿素-甲醛(PUF)树脂中原料共缩聚反应是否发生,并确认共缩聚分子形成特点,借助13C核磁共振(13C NMR)和基质辅助激光解析电离飞行时间质谱(MALDI-TOF-MS)两种主要分析仪器,对比研究了苯酚-甲醛(PF)树脂和PUF树脂的结构特点,结果证实了PUF树脂中苯酚、尿素和甲醛3种原料之间共缩聚反应的存在,认为PUF树脂结构以PF树脂为主体,且共缩聚结构主要形成于合成反应初期。杜官本 雷洪 PIZZI Antonio 2013林产化学与工业2013,33,1:7
8乙二醛-尿素树脂提高脲醛树脂固化速率和性能的研究显示文摘在酸性介质中合成了一种无F(甲醛)的环保型GU(乙二醛-尿素树脂),并探讨了其用作UF(脲醛树脂)固化剂的可行性。研究结果表明:GU含有共轭结构、大量的氨基和羟基等活性基团,并且其Mr(相对分子质量)分布较宽且比较零散,主要以加成产物和低聚物为主;当m(GU)∶m(UF)=5∶95时,不另加固化剂而制备的胶合板之干态胶接强度和F释放量,均满足GB/T 9846.3—2004标准中的指标要求。邓书端 汪进 杜官本 Pizzi Antonio 2016中国胶粘剂2016,25,5:5
9云南松树皮单宁树脂砂轮切割片的制备及性能研究显示文摘以云南松单宁和糠醇为主要原料,氧化铝颗粒为研磨材料,在实验室条件下制备新型可回收砂轮切割片来替代工业酚醛树脂砂轮切割片。同时对材料的抗压、抗弯性能,布氏硬度及切割性能进行了研究。结果表明:按同一工艺制备的单宁树脂砂轮切割片的抗压、抗弯性能及硬度均高于酚醛树脂砂轮切割片,并且二者的切割性能相似。因此,采用天然可回收云南松单宁树脂砂轮切割片来替代石油产物酚醛树脂砂轮切割是可行的。张俊 杜官本 邓书端 Pizzi Antonio 王辉 2016化工新型材料2016,44,6:5
10Organosolv Lignin for Non-Isocyanate Based Polyurethanes (NIPU) as Wood Adhesive显示文摘A non-isocyanate-based polyurethane(NIPU)wood adhesive was produced from organosolv lignin,which is a bio-sourced raw material,available in large quantities and produced as a by-product of the paper industry.The formulation of this new lignin-based NIPU adhesive,which is presented,was chemically characterised by Matrix-Assisted Laser Desorption Ionization Time of Flight(MALDI ToF)mass spectrometry and by Fourier Transform Infra-Red(FTIR)spectrometry analyses.The oligomers formed were determined and showed that the three species involved in the NIPU adhesive preparation were formed by the co-reaction of the three reagents used:lignin,dimethyl carbonate,and hexamethylene diamine.Linear and branched structures were both identi-fied.Mechanical properties of the adhesive were determined using the Automated Bonding Evaluation System(ABES)and internal bond(IB)strength test of the laboratory particleboard bonded with it.The adhesive has shown satisfactory mechanical properties after hot pressing at 230℃.Such a temperature is used industrially in the most modern particleboard factories,but since it is hardly feasible for more conventional wood bonding equipment,the reactivity of the NIPU adhesive was successfully increased with the addition of a small percentage of a silane coupling agent.With the addition of the silane,the proposed NIPU adhesive could also be used at a hot-pressing temperature lower than 200℃.Jaša Saražin Antonio Pizzi Siham Amirou Detlef Schmiedl MilanŠernek 2021Journal of Renewable Materials2021,9,5:4
11Automated high-throughput Wannierisation显示文摘Maximally-localised Wannier functions(MLWFs)are routinely used to compute from first-principles advanced materials properties that require very dense Brillouin zone integration and to build accurate tight-binding models for scale-bridging simulations.At the same time,high-throughput(HT)computational materials design is an emergent field that promises to accelerate reliable and cost-effective design and optimisation of new materials with target properties.The use of MLWFs in HT workflows has been hampered by the fact that generating MLWFs automatically and robustly without any user intervention and for arbitrary materials is,in general,very challenging.We address this problem directly by proposing a procedure for automatically generating MLWFs for HT frameworks.Our approach is based on the selected columns of the density matrix method and we present the details of its implementation in an AiiDA workflow.We apply our approach to a dataset of 200 bulk crystalline materials that span a wide structural and chemical space.We assess the quality of our MLWFs in terms of the accuracy of the band-structure interpolation that they provide as compared to the band-structure obtained via full first-principles calculations.Finally,we provide a downloadable virtual machine that can be used to reproduce the results of this paper,including all first-principles and atomistic simulations as well as the computational workflows.Valerio Vitale Giovanni Pizzi Antimo Marrazzo Jonathan R.Yates Nicola Marzari Arash A.Mostofi 2020npj Computational Materials2020,,1:4

13No-Aldehydes Glucose/Sucrose-Triacetin-Diamine Wood Adhesives for Particleboard显示文摘A three reagents adhesive system for wood particleboards not containing any aldehyde was developed by the reaction of glucose or sucrose with triacetin(glycerin triacetate)and with hexamethylene diamine.The system was found to be based on the mix of three reactions,namely the reaction of(i)glucose with triacetin,(ii)of the diamine with triacetin,and(iii)of glucose with the diamine.The chemical species formed were identified by Matrix Assisted Laser Desorption Ionization Time of Flight(MALDI-ToF)mass spectrometry.Wood particleboard panels were prepared with this adhesive system and gave good internal bond(IB)strength results suitable for interior grade panels and with extremely low formaldehyde emission.Xuedong Xi Antonio Pizzi 2020Journal of Renewable Materials2020,8,7:2
14Soy Protein Isolate Non-Isocyanates Polyurethanes(NIPU)Wood Adhesives显示文摘Soy-protein isolate(SPI)was used to prepare non-isocyanate polyurethane(NIPU)thermosetting adhesives for wood panels by reacting it with dimethyl carbonate(DMC)and hexamethylene diamine.Both linear as well as branched oligomers were obtained and identified,indicating how such oligomer structures could further cross-link to form a hardened network.Unusual structures were observed,namely carbamic acid-derived urethane linkages coupled with lactam structures.The curing of the adhesive was followed by thermomechanical analysis(TMA).It appeared to follow a two stages process:First,at a lower temperature(maximum 130℃),the growth of linear oligomers occurred,finally forming a physically entangled network.This appeared to collapse and disentangle,causing a decrease of MOE,as the temperature increases.This appears to be due to the ever more marked Brownian movements of the linear oligomer chains with the increase of the temperature.Second,chemical cross-linking of the chains appeared to ensue,forming a hardened network.This was shown by the thermomechanical analysis(TMA)showing two distinct MOE maxima peaks,one around 130℃ and the other around 220℃,with a very marked MOE decrease between the two.Plywood panels were prepared and bonded with the SPI-NIPU wood adhesive and the results obtained are presented.The adhesive appeared to pass comfortably the requirements for dry strength of relevant standards,showing to be suitable for interior grade plywood panels.It did not pass the requirements for wet tests.However,addition of 15%of glycerol diglycidyl ether improved the wet tests results but still not enough to satisfy the standards requirements.Xinyi Chen Antonio Pizzi Xuedong Xi Xiaojian Zhou Emmanuel Fredon Christine Gerardin 2021Journal of Renewable Materials2021,9,6:2

16植物鞣剂/MUF树脂鞣制时皮革的耐光性及鞣剂的抗老化性显示文摘制备了一种蜜胺含量相对较低的新型磺化蜜胺-脲-甲醛(MUF)缩聚树脂,此树脂与不同的天然植物鞣质复合鞣革,成革具有和铬鞣革一样良好的性能。提出了不同的鞣质/MUF树脂复合物鞣制的皮革,在长时间的紫外线辐射下,以革色的变化作为老化时间的函数,建立并阐明了此函数的预测模型和公式。此函数不仅与固态纯鞣质的抗老化能力有关,还与其在皮革内总体的抗老化能力有关。B George A Pizzi C Simon M C Triboulot 张业聪 付丽红 2007中国皮革2007,36,15:2
17Successful multidisciplinary clinical approach and molecular characterization by whole transcriptome sequencing of a cardiac myxofibrosarcoma: A case report显示文摘BACKGROUND Cardiac tumors are rare and complex entities.Surgery represents the cornerstone of therapy,while the role of adjuvant treatment remains unclear and,in case of relapse or metastatic disease,the prognosis is very poor.Lack of prospective,randomized clinical trials hinders the generation of high level evidence for the optimal diagnostic workup and multimodal treatment of cardiac sarcomas.Herein,we describe the multidisciplinary clinical management and molecular characterization of a rare case of cardiac myxofibrosarcoma in an elderly woman.CASE SUMMARY A 73-year-old woman presented signs and symptoms of acute left-sided heart failure.Imaging examination revealed a large,left atrial mass.With suspicion of a myxoma,she underwent surgery,and symptoms were promptly relieved.Histology showed a cardiac myxofibrosarcoma,a rare histotype of cardiac sarcoma.Eight months later,disease unfortunately relapsed,and after a multidisciplinary discussion,a chemotherapy with doxorubicin and then gemcitabine was started,achieving partial radiologic and complete metabolic response,which was maintained up to 2 years and is still present.This report is focused on the entire clinical path of our patient from diagnosis to follow-up,through surgery and strategies adopted at relapse.Moreover,due to their rarity,very little is known about the molecular landscape of myxofibrosarcomas.Thus,we also performed and described preliminary genome analysis of the tumor tissue to get further insight on mechanisms involved in tumor growth,and to possibly unveil new clinically actionable targets.CONCLUSION We report a case of cardiac myxofibrosarcoma that achieved a very good prognosis due to an integrated surgical,cardiac and oncologic treatment strategy.Maristella Saponara Valentina Indio Carmine Pizzi Elena-Daniela Serban Milena Urbini Annalisa Astolfi Pasquale Paolisso Sofia Martin Suarez Margherita Nannini Davide Pacini Valentina Agostini Ornella Leone Valentina Ambrosini Giuseppe Tarantino Stefano Fanti Fabio Niro Francesco Buia Domenico Attinà Maria Abbondanza Pantaleo 2019World Journal of Clinical Cases2019,7,19:2
18Curing Kinetics of Tannin and Lignin Biobased Adhesives Determined by DSC and ABES显示文摘The curing process of two biobased adhesives:pine tanninhexamine(TH)and organosolv lignin non-isocyanate polyurethane(NIPU),suitable for interior nonstructural use,were compared with commercial urea-formaldehyde(UF)adhesive.Changes in chemical structure before and after the curing process were observed with Fouriertransform infrared spectroscopy(FTIR).The process of adhesive curing was monitored with differential scanning calorimetry(DSC)and the automated bonding evaluation system(ABES).Both DSC and ABES measurements confirmed UF as the fastest and NIPU as the slowest curing adhesive observed.Taking into account the ABES results,the optimal pressing parameters for the TH adhesive would be 4 min at 175℃,for the NIPU adhesive 7 min at 200℃and for the UF 1.5 min at 100℃.Strong linear correlation was observed between mechanical and chemical curing for the UF and NIPU adhesives,whereas lower correlation was observed for the TH adhesive.At all observed adhesives,the DSC measurements were underestimating the curing process determined by ABES in the first part and overestimating it at the end.The underestimation was the most evident with the TH adhesive and the less with the UF adhesive.When comparing the uncured and cured FTIR spectra of all three types of adhesives,a drastic decrease in the characteristic band of-OH groups at 3330–3400 cm^(−1)and an increase in the signal intensity at 2920 cm^(−1)of aliphatic-CH2-groups were observed.For the UF adhesive,the C=O stretching frequency has shifted from 1632 cm^(−1)for uncured to three different bands at 1766,1701,and 1655 cm^(−1)for cured UF.The sharp band for phenolic alcohols at 1236 cm^(−1)of C–O stretch and hydroxyl O–H functional group at 1009 cm^(−1)and at 684 cm^(−1)of uncured TH adhesive diminished during curing,which indicates that a crosslinking reaction occurs via-OH groups.The peak of the C=O group of urethane bridges at 1697 cm^(−1)for uncured NIPU shifted to lower wavenumber at 1633 cm^(−1)for cured NIPU.Jaša Saražin Ida Poljanšek Antonio Pizzi MilanŠernek 2022Journal of Renewable Materials2022,10,8:2
