| 1 | 润滑油抗氧剂协同作用研究显示文摘对润滑油的氧化机理做了简要阐述,并根据不同的抗氧作用机理,将抗氧剂分为三类:自由基清除剂(如酚类和胺类抗氧剂)、氢过氧化物分解剂(如氨基甲酸酯)和抗氧协合剂(如不含硫磷的钼酸酯)。利用加压差示扫描量热法(PDSC)对不同类型抗氧剂以及它们之间的协同作用进行了考察。研究表明,作为氢过氧化物分解剂,改进的无灰氨基甲酸酯具有比胺类、酚类抗氧剂更好的性能,这显示了氢过氧化物分解型抗氧剂巨大的应用潜力。研究还表明,具有相同抗氧机理的不同抗氧剂,如酚类和胺类抗氧剂,具有协同作用;不同作用机理的两抗氧剂之间,如自由基清除剂和氢过氧化物分解剂,具有更好的抗氧化协同效果,其中,无灰氨基甲酸酯与烷基化二苯胺抗氧剂具有最佳的抗氧协同效能,可成为高温无灰抗氧剂应用的一个很好选择;不同抗氧机理的三种抗氧剂复合,如烷基化二苯胺,氨基甲酸锌和有机钼酸酯组成的三元复合抗氧剂,具有更为优秀的抗氧化性能。通过不同机理抗氧剂之间的协同,不仅可以获得优秀的抗氧化性能,还可获得附加的极压、抗磨和减摩性能,而且有的减摩、抗磨性能还非常突出,如烷基化二苯胺、氨基甲酸锌和有机钼酸酯组成的三元复合添加剂体系。 | 姚俊兵 Gaston Aguilar Steven G.

| 3 | Mechanical thrombectomy in patients with M1 occlusion and NIHSS score≤5:a single-centre experience显示文摘Background:The recent success of several mechanical thrombectomy trials has resulted in a significant change in management for patients presenting with stroke.However,it is still unclear how to manage patients that present with stroke and low National Institutes of Health Stroke Scale(NIHSS)≤5.We sought to review our experience of mechanical thrombectomy in patients with low NIHSS and confirmed M1 occlusion.Methods:We retrospectively analysed our prospectively maintained database of all patients undergoing mechanical thrombectomy between January 2008 and August 2016.We identified 41 patients with confirmed M1 occlusion and low NIHSS(≤5)on admission to our hospital.We collected demographic,radiological,procedural and outcome data.Results:The mean age of patients was 72±14,with 20 male patients.Associated medical conditions were common with hypertension seen in∼80%.Just over 50%presented with NIHSS 4 or 5.The average ASPECTS score on admission was 8.8(range 6–10),and the average clot length 10 mm.Angiographically Thrombolysis in Cerebral Infarction(TICI)≥2b was obtained in 87.8%of patients.7 patients had haemorrhage on follow-up,2 of which were symptomatic.Of 40 patients with 90-day follow-up,75%had modified Rankin Scale(mRS)score 0–2.There were 3 deaths at 90 days.Conclusions:Mechanical thrombectomy in patients with low NIHSS and proximal large vessel occlusion is technically possible and carries a high degree of success with good safety profile.Patients with low NIHSS and confirmed occlusion should be considered for mechanical thrombectomy. | P Bhogal P Bucke O Ganslandt H Bazner H Henkes M Aguilar Perez | 2016 | Stroke & Vascular Neurology2016，1，4： | 9 |

| 5 | 发动机油非磷抗氧、抗磨、减摩添加剂协同研究显示文摘降低发动机油的磷含量,提高燃料经济性,延长使用寿命,已是润滑油升级换代大势所趋。为了降低磷的含量,必须减少二烷基二硫代磷酸锌(ZnDDP)的使用,而二烷基二硫代氨基甲酸锌(ZnDDC)是ZnDDP最理想的替代物。为了提高油品的燃料经济性,需要加入有机钼摩擦改进剂,其中,不含硫磷的钼酸酯添加剂,因其良好的减摩保持性,其应用更为突出。为了满足更苛刻的油品高温性能要求,还必须加入烷基化二苯胺类抗氧剂(AD-PA)。因此有必要对非活性钼、ZnDDC和ADPA之间相互作用进行考察。研究表明,在非活性有机钼、ZnDDC、ADPA的三元添加剂体系中,存在着三种相互配合的协同作用:ZnDDC与非活性有机钼的抗磨协同,非活性有机钼与ADPA的抗氧化协同,以及ZnDDC与ADPA的抗氧化协同。利用非活性有机钼、ZnDDC、ADPA的三元非磷协同复合体系(OD 0401),可以大幅度提高油品的抗氧化性能、减摩性能和抗磨性能,这对发展低磷含量的GF-4和GF-5发动机润滑油具有十分积极的意义。利用该协同复合添加剂OD 0401,还可以有效地提高低档发动机油的抗氧化和抗磨性能。 | 姚俊兵 Glenn A.Mazzamaro Gaston Aguilar Steve G.Donnelly | 2008 | 润滑油2008，23，2： | 5 |
| 6 | Red pigment production by Penicillium purpurogenum GH2 is influenced by pH and temperature显示文摘The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with D-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demon- strates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L). | Alejandro MéNDEZ Catalina PéREZ Julio Cesar MONTAéZ Gabriela MARTíNEZ Cristóbal Noé AGUILAR | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，12： | 4 |

| 8 | Preparation of neodymium-doped yttrium aluminum garnet powders and fibers显示文摘Using nitrate precursors, a novel spray-drying assisted citrate gel process for the preparation of neodymium-doped yttrium alumi- num garnet (YAG) phase was developed. Synthesis of single-phase polycrystalline YAG was achieved at temperatures as low as 800 °C us- ing the spray-drying methodology whilst conventional approaches currently available require 1000 °C. Initially, a solution was prepared by mixing aluminum and yttrium nitrates, citric acid, etilenglycol and neodymium oxide. This solution was dried by pulverization (spray dryer) to obtain aggregated precursor powders of the compound. These aggregates were calcined at 800, 850 and 900 °C to determine the phase evolution from amorphous to crystalline by X-ray diffraction (XRD). The morphology of aggregates was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Moreover, through XRD it was determined that the crystallization of YAG phase started at about 800 °C without any intermediate phases. The powders were composed of spherical aggregates with an average diame- ter of 1 μm. From these powders, ceramic fibers with additions of 2at.% and 5at.% Nd, were extracted from the melt with diameters ranging from 30 μm to 50 μm. | R. López J. Zárate E. A. Aguilar J.

| 11 | Toll-like receptor 4 and protease-activated receptor 2 in physiology and pathophysiology of the nervous system:more than just receptor cooperation?显示文摘Toll-like receptor 4(TLR4) and protease-activated receptor 2(PAR2) play pivotal roles in the mammalian innate immune response.Notably,in addition to their involvement in detection of invading pathogens,PAR2 and TLR4 modulate the levels of cell death-induced sterile inflammation by activating pro-or anti-inflammatory downstream signaling cascades.Within the central nervous system,there is emerging evidence that both receptors are involved in synaptic transmission and brain plasticity.Furthermore,due to their prominent role in mediating neuroinflammation,PAR2 and TLR4 are associated with development and progression of neurodegenerative disorders including but not limited to Alzheimer's disease,Parkinson's disease and multiple sclerosis.In this article,we summarise the current knowledge on the cooperation between PAR2 and TLR4,discuss the potential cross-talk levels and highlight the impact of the cross-coupling on neuroinflammation. | Darius Widera Rocío Martínez Aguilar Graeme S.Cottrell | 2019 | Neural Regeneration Research2019，14，7： | 3 |

| 13 | Resection of the uncinate process of the pancreas due to a ganglioneuroma显示文摘A 33-year-old woman who presented with epigastric discomfort and diarrhea underwent an abdominal ultrasound(US).This investigation and subsequent contrastenhanced computed tomography,magnetic resonance imaging and endoscopic US with fine needle aspiration (FNA)revealed a 40 mm well-circumscribed mass in the uncinate process of the pancreas.Findings were suggestive of a mucinous or solid-cystic pseudopapillary tumor of the pancreas,although other lesions such as a nonfunctioning neuroendocrine tumor could not be ruled out.FNA samples were negative for malignant cells,but of limited value due to poor cellularity.It was decided to surgically remove the tumor because malignancy could not be discounted.Multiple intraoperative biopsies were suggestive of mesenchymal tumor and consequently a conservative resection(uncinatectomy)was performed. The postoperative course was uneventful.The definitive diagnosis was ganglioneuroma.Immunocytochemistry showed positive staining with vimentin,S-100 protein, neurofilament and neuron-specific enolase.Ganglioneuroma is a rare benign tumor that can also present as a pancreatic tumor.Uncinatectomy is feasible,safe and a good surgical technique for the treatment of nonmalignant tumors located in the uncinate process of the pancreas. | Ignasi Poves Fernando Burdío Mar Iglesias María de los ángeles Martínez-Serrano Guadalupe Aguilar Luís Grande | 2009 | World Journal of Gastroenterology2009，15，34： | 3 |

| 15 | Client-level predictors of treatment engagement,outcome and dropout:moving beyond demographics显示文摘Background Despite the availability of evidence-based treatments for posttraumatic stress disorder(PTSD),significant heterogeneity in the effectiveness of PTSD treatment persists,especially in community settings.Client demographics used to understand this variability in treatment outcome and dropout have yielded mixed results.Despite increasing evidence for the importance of attending to treatment engagement in community settings,few studies have explored client-level predictors.Aim The purpose of this study is to explore client-level predictors of treatment outcome and dropout beyond client demographics,and to identify client-level predictors of treatment engagement in community settings.Method Secondary data analysis was conducted with data collected as part of an implementation-effectiveness hybrid study of cognitive processing therapy(CPT)for PTSD in a diverse community healthcentre.Providers(n=19)treated(n=52)clients as part of their routine clinical care.Non-demographic client-level predictors included barriers to treatment,quality of life,session-level language and employment history assessed at baseline.Treatment engagement included number of weeks in the study,number of sessions with repeated CPT content,number of unique CPT sessions attended,frequency of session attendance and consistency of session attendance.Results Results showed language as a significant predictor of treatment engagement.There were significant differences between Spanish and English-speaking clients,with the former having a tendency to repeat more session content than the latter(β=1.4 sessions,p=0.003),and also less likely to attend treatment frequently(r=0.62,p=0.009)and consistently(r=0.57,p=0.027)if high logistical and financial barriers were endorsed.Irrespective of language,clients who reported high quality of life at baseline were less likely to repeat CPT session content(β=-0.3,p=0.04),and those with increased baseline barriers to treatment had deceleration in PTSD symptom improvement over time(β=-0.62,p<0.05).In terms of treatment engagement moderators impacting treatment outcome,clients who repeated more session content were more likely to complete treatment(0R=1.84,p=0.037).Conclusion Identification of client-level predictors of treatment engagement,outcome and dropout is essential to optimise treatment,particularly in community settings. | Soo-jeong Youn Margaret-Anne Mackintosh Shannon Wiltsey Stirman Kay lie A Patrick Yesenia Aguilar Silvan Anna D Bartuska Derri L Shtasel Luana Marques | 2019 | General Psychiatry2019，32，6： | 2 |

| 17 | Ag-Zn粉末的机械合金化和随后的热处理(英文)显示文摘研究了在机械合金化过程中Ag和Zn以及随后的热处理中的显微组织演变。机械合金化在SPEX8000D铣床中进行。采用X射线衍射(XRD)﹑透射电子显微镜(TEM)和扫描电子显微镜(SEM)观察样品的显微组织。使用差示扫描量热计(DSC)研究样品的热性能。结果表明,在合金化初期的碾磨过程中能观察到ε,β,β′,α固溶体和剩余的Zn。随后,ε,β,β′和Zn相消失,α固溶体中的Zn浓度剧烈升高。在碾磨7.2ks后,机械合金化过程达到稳定状态。在此期间,α固溶体的组分和晶粒尺寸保持不变。后续热处理表明α固溶体也能够通过机械合金化结合热处理得到。最后,为了得到α固溶体,根据碾磨和热处理过程中样品的微观组织演变,提出一个最佳的工艺路线。 | Danny GUZMN Oscar RIVERA Claudio AGUILAR Stella ORDOEZ Carola MARTíNEZ Daniel SERAFINI Paula ROJAS | 2013 | Transactions of Nonferrous Metals Society of China2013，23，7： | 2 |

| 20 | Demographic trends and climate over 35 years in the Barro Colorado 50 ha plot显示文摘Background:The first three censuses of the 50-ha plot at Barro Colorado Island spanned an unusually harsh dry season during the 1983 El Nino.By the early 1990 s,we had documented increases in tree mortality,tree growth,and large population fluctuations of many species during the 1982-1985 census interval.At the time,we asserted that increasing drought frequency would greatly affect the forest.With the benefit of five more censuses at Barro Colorado from 1995-2015,we can now put the 1980 conditions in a longer perspective and test the hypothesis that increasing droughtiness has continued to change the forest.Methods:A 50-ha forest plot on Barro Colorado Island was censused eight times,in 1982 and every five years since1985.All free-standing woody stems were measured,mapped,and identified In each census.Results:1) The period 1982-1992 included several extreme dry seasons,not just 1983,but since then there have been few such droughts.2) Dbh growth declined from a peak in the early 1980 s to its lowest in the early 1990 s.From 1995-2015 it increased slightly,but not returning to the initial peak.Nearly every species and all dbh categories followed the same pattern.3) The elevated stand-wide mortality rate of large trees during the 1982-1985 drought has not returned,and most individual species showed the same pattern of elevated mortality in the 1980 s followed by low and fairly stable mortality after 1990.4) Sapling mortality declined after 1985,but rose again in the late-90 s,so the 1980 s drought period no longer looks unusual.Mortality of individual species' saplings fluctuated erratically,including cases where mortality during the drought was lower than after.5) Population sizes of individual species fluctuated in all possible directions.Some species declined precipitously during the drought,then recovered,but others did not recover.Other species increased in abundance during the drought.Conclusions:Droughts of the 1980 s elevated tree growth and mortality at Barro Colorado,but since 1990,demographic rates have remained lower,paralleling a moderate climate with few severe droughts after 1990.Moisture-demanding species suffered during the drought,but many have since recovered.We do not know how often such drought periods recur.Moreover,many species' abundances fluctuated over 35 years with no known cause. | Richard Condit Rolando Pérez Suzanne Lao Salomón Aguilar Stephen P.
