1Evaluation of inflammatory activity in Crohn's disease and ulcerative colitis显示文摘Crohn's disease and ulcerative colitis evolve with a relapsing and remitting course.Determination of inflammatory state is crucial for the assessment of disease activity and for tailoring therapy.However,no simple diagnostic test for monitoring intestinal inflammation is available.Noninvasive markers give only indirect assessments of disease activity.Histopathological or endoscopical examinations accurately assess inflammatory activity,but they are invasive,time consuming and expensive and therefore are unsuitable for routine use.Imaging procedures are not applicable for ulcerative colitis.The usefulness of ultrasound and Doppler imag-ing in assessing disease activity is still a matter of discussion for Crohn's disease,and an increased interest in computed tomography enterograph (CTE) has been seen,mainly because it can delineate the extent and severity of bowel wall inflammation,besides detecting extraluminal findings.Until now,the available data concerning the accuracy of magnetic resonance enterography in detecting disease activity is less than CTE.Due to this,clinical activity indices are still commonly used for both diseases.Eduardo Garcia Vilela Henrique Osvaldo da Gama Torres Fabiana Paiva Martins Maria de Lourdes de Abreu Ferrari Marcella Menezes Andrade Aloísio Sales da Cunha 2012World Journal of Gastroenterology2012,18,9:23

7Posterior partially edentulous jaws, planning a rehabilitation with dental implants显示文摘AIM: To discuss important characteristics of the useof dental implants in posterior quadrants and the rehabilitation planning. METHODS: An electronic search of English articles was conducted on MEDLINE(PubM ed) from 1990 up to the period of March 2014. The key terms were dental implants and posterior jaws, dental implants/treatment planning and posterior maxilla, and dental implants/treatment planning and posterior mandible. No exclusion criteria were used for the initial search. Clinical trials, randomized and non randomized studies, classical and comparative studies, multicenter studies, in vitro and in vivo studies, case reports, longitudinal studies and reviews of the literature were included in this review. RESULTS: One hundred and fifty-two articles met the inclusion criteria of treatment planning of dental implants in posterior jaw and were read in their entirety. The selected articles were categorized with respect to their context on space for restoration, anatomic considerations(bone quantity and density), radiographic techniques, implant selection(number, position, diameter and surface), tilted and pterygoid implants, short implants, occlusal considerations, and success rates of implants placed in the posterior region. The results derived from the review process were described under several different topic headings to give readers a clear overview of the literature. In general, it was observed that the use of dental implants in posterior region requires a careful treatment plan. It is important that the practitioner has knowledge about the theme to evaluate the treatment parameters. CONCLUSION: The use of implants to restore the posterior arch presents many challenges and requires a detailed treatment planning.Douglas R Monteiro Emily V F Silva Eduardo P Pellizzer Osvaldo Magro Filho Marcelo C Goiato 2015World Journal of Clinical Cases2015,3,1:6
8Physico-chemical properties and structure of rice cultivars grown in Heilongjiang Province of China显示文摘The relationships between chemical composition,structure and physicochemical properties such as pasting,thermal,and textural properties of 12 temperate rice cultivars grown in Heilongjiang Province,China were investigated in this study.There were significant differences in the content of fat,protein,ash,amylose,damaged starch among 12 cultivars.Brabender Viscograph results showed that gelatinization time,peak viscosity,pasting and peak temperature ranged from 9 min to 15 min,2100 BU to 2500 BU,58.75℃to 72.00℃and 63.75℃to 84.45℃,respectively,except for the waxy one Longjing 9.To,Tp,Tc andΔH were found in the range of 58.34℃to 67.96℃,65.39℃to 75.38℃,78.47℃to 90.69℃and 2.036 J/g to 3.127 J/g respectively.Scanning Electron Micro-photograph results showed that all starch granules were polyhedral with irregular shapes,except Longjing 9 showing signs of the loss of physical integrity.The hardness,adhesiveness,springiness,gumminess,cohesiveness and resilience ranged from 395.87 g to 1161.76 g,-90.842 g·mm to-36.4 g·mm,0.498 to 0.747,78.631 g to 466.837 g,0.199 to 0.569,0.321 to 0.504,respectively.Correlation studies indicated that amylose,damaged starch,protein,fat and ash played a more important role in determining the rice properties of pasting,thermal,crystallinity and texture.Yinyuan He Fenglian Chen Yanguo Shi Zhexian Guan Na Zhang Osvaldo HCampanella 2021Food Science and Human Wellness2021,10,1:5

10Catalytic combustion of soot over ceria-zinc mixed oxides catalysts supported onto cordierite显示文摘Modified substrates as outer heterogeneous catalysts was employed to reduce the soot generated from incomplete combustion of diesel or diesel/biodiesel blends, a process that harms the environment and public health. The unique storage properties of ceria(CeO2) makes it one of the most efficient catalysts available to date. Here, we proposed that ceria-based catalysts can lower the temperature at which soot combustion occurs; more specifically, from 610℃ to values included in the diesel exhausts operation range(300–450℃). The sol-gel method was used to synthesize mixed oxide-based catalysts(CeO2:ZnO); the resulting catalysts were deposited onto cordierite substrates. In addition, the morphological and structural properties of the material were evaluated by XRD, BET, TPR-H2, and SEM. Thermogravimetric(TG/DTA) analysis revealed that the presence of the catalyst decreased the soot combustion temperature by 200℃ on average, indicating that the oxygen species arise at low temperatures in this situation, promoting highly reactive oxidation reactions. Comparative analysis of soot emission by diffuse reflectance spectroscopy(DRS) showed that catalyst-impregnated cordierite samples efficiently oxidized soot in a diesel/biodiesel stationary motor: soot emission decreased by more than 70%.Leandro Fontanetti Nascimento Renata Figueredo Martins Rodrigo Ferreira Silva Osvaldo Antonio Serra 2014Journal of Environmental Sciences2014,26,3:5
11Treatability studies of naphthalene in soil,water and air with persulfate activated by iron(Ⅱ)显示文摘Chemical oxidation was applied to an artificially contaminated soil with naphthalene(NAP).Evaluation of NAP distribution and mass reduction in soil,water and air phases was carried out through mass balance.Evaluation of NAP distribution and mass reduction in soil,water and air phases was carried out through mass balance.The importance of the air phase analysis was emphasized by demonstrating how NAP behaves in a sealed system over a 4 hr reaction period.Design of Experiments method was applied to the following variables:sodium persulfate concentration[SP],ferrous sulfate concentration[FeS04],and pH.The system operated with a prefixed solid to liquid ratio of 1:2.The following conditions resulted in optimum NAP removal[SP]=18.37 g/L,[FeSO4]=4.25 g/L and pH=3.00.At the end of the 4 hr reaction,62%of NAP was degraded.In the soil phase,the chemical oxidation reduced the NAP concentration thus achieving levels which comply with Brazilian and USA environmental legislations.Besides the NAP partitioning view,the monitoring of each phase allowed the variabilities assessment over the process,refining the knowledge of mass reduction.Based on NAP distribution in the system,this study demonstrates the importance of evaluating the presence of semi-volatile and volatile organic compounds in the air phase during remediation,so that there is greater control of the system as to the distribution and presence of the contaminant in the environment.The results highlight the importance of treating the contaminant in all its phases at the contaminated site.Gabriela P.Mendes Vivian M.A.Magalhaes Lélia C·R·Soares Rayanne M.Aranha Claudio A.O.Nascimento Marilda M.G.R.Vianna Osvaldo Chiavone-Filho 2020Journal of Environmental Sciences2020,32,4:4
12Short- and long-term efficacy of endoscopic balloon dilation in Crohn's disease strictures显示文摘AIM:To evaluate short- and long-term efficacy of endoscopic balloon dilation in a cohort of consecutive patients with symptomatic Crohn's disease (CD)-related strictures. METHODS:Twenty-six CD patients (11 men; median age 36.8 year, range 11-65 years) with 27 symptomatic strictures underwent endoscopic balloon dilation (EBD).Both naive and post-operative strictures, of any length and diameter, with or without associated fistula were included. After a clinical and radiological assessment, EBD was performed with a Microvasive Rigiflex through the scope balloon system. The procedure was considered successful if no symptom reoccurred in the following 6 mo. The long-term clinical outcome was to avoid surgery. RESULTS:The mean follow-up time was 40.7 ± 5.7 mo (range 10-94 mo). In this period, forty-six EBD were performed with a technical success of 100%. No procedure-related complication was reported. Surgery was avoided in 92.6% of the patients during the entire follow-up. Two patients, both presenting ileocecal strictures associated with fistula, failed to respond to the treatment and underwent surgical strictures resection. Of the 24 patients who did not undergo surgery, 11 patients received 1 EBD, and 13 required further dilations over time for the treatment of relapsing strictures (7 patients underwent 2 dilations, 5 patients 3 dilations, and 1 patient 4 dilations). Overall, the EBD success rate after the first dilation was 81.5%. No difference was observed between the EBD success rate for naive (n = 12) and post-operative (n = 15) CD related strictures (P > 0.05). CONCLUSION:EBD appears to be a safe and effective procedure in the therapeutic management of CD-related strictures of any origin and dimension in order to prevent surgery.Nicola de'Angelis Maria Clotilde Carra Osvaldo Borrelli Barbara Bizzarri Francesca Vincenzi Fabiola Fornaroli Giuseppina De Caro Gian Luigi de'Angelis 2013World Journal of Gastroenterology2013,19,17:4

14分子动力学模拟研究直链淀粉与α-亚油酸的包合行为显示文摘α-亚油酸和直链淀粉可以形成热力学稳定复合物。为了研究α-亚油酸影响直链淀粉构象的机理、复合物的构象趋势及复合作用过程中氢键的变化情况,在373 K条件下进行了长时间(500 ns)的全原子分子动力学模拟。模拟发现在有/无α-亚油酸存在的情况下,在500 ns内都可以观察到大量有序到无序的构象转变,这表明直链淀粉和α-亚油酸之间结合作用微弱。原子均方根偏差(RMSD)、α-亚油酸与直链淀粉轴心间距、氢键增加都证明直链淀粉-α-亚油酸复合物的形成是热力学自发行为。冯涛 王旭 庄海宁 Feng Chen Bruce R Hamaker Osvaldo Campanella 王凯 2016中国粮油学报2016,31,4:3

17短链葡聚糖包合姜黄素的分子机制显示文摘通过利用普鲁兰酶来酶解蜡质玉米淀粉而得到的短链葡聚糖来包合姜黄素,可以极大地提高姜黄素的水溶性。本研究还使用新型的计算机模拟的方法来分析短链葡聚糖和姜黄素的包合行为机制,模拟了短链葡聚糖-姜黄素包合物在600 ns内的分子包合行为。从模拟轨迹中获取的自组装快照图,可以知道包合物的结合方式是边解离边复合最后趋于稳定结构的包合方式。通过体系回转半径反应了短链葡聚糖随着时间与姜黄素包合行为过程中的构象变化,结果与快照图一致。体系溶解性较好,模拟得知的结果与实验基本一致,短链葡聚糖-姜黄素的溶解性高于单独的姜黄素水溶液,提高了姜黄素的生物利用率。为医学领域寻找合适的药物壁材提供了一种新的研究途径。冯涛 曾小兰 张钰 Marcelo Carignano Osvaldo Campanella 李晓玺 2018现代食品科技2018,34,10:2
18Reconstruction of debris-flow activity in a temperate mountain forest catchment of central Mexico显示文摘The use of dendrochronology to study and date geomorphic processes in volcanic environments is still incipient, even more so on the volcanic slopes covered by temperate forests in central Mexico. Mass movements, such as debris flows, often impact forest stands where they cause damage to individual trees, thereby generating growth disturbances(GD) in the tree-ring records. The identification and dating of GD enables reconstruction of the age of trees colonizing bare surfaces after major events, but also allows the assessment of the frequency or spatial distribution of past geomorphic process activity. Here we used increment cores from 65 Pinus leiophylla, Abies religiosa, and Alnus jorullensis trees growing in the Axal gorge, on the southern slopes of La Malinche volcano, to unravel past debris-flow activity both temporally and spatially. Based on the combination of GD records, a weighted tree response index(Wit), field evidence and hydrometeorological records, we reconstructed 23 debris flows since 1933.Interestingly, almost two-thirds of the reconstructed years with debris-flow activity in Axal gorge match with events recorded in Axaltzintle gorge located on the NE slopes of La Malinche. These findings suggest a regional triggering mechanism, most likely related to the occurrence of hurricanes. This research could be useful for disaster risk management of the La Malinche National Park.Osvaldo FRANCO-RAMOS Markus STOFFEL Juan Antonio BALLESTEROS-CANOVAS 2019Journal of Mountain Science2019,16,9:2
