| 1 | 对明串珠菌及其他细菌的抑制效果显示文摘在从压榨间直到蔗汁澄清的蔗糖生产过程中,蔗汁中微生物活动是破坏蔗糖品质的一个重要因素。蔗糖损失和葡聚糖的形成通常与蔗汁中微生物引起的变质有关。多年来,这一直成为糖厂试图改善蔗糖品质时所面临的问题。本文以直接影响得糖率的微生物减少和相对纯度为指标,研究了不同杀菌方法在蔗汁中的效果。浓度为0.007%的S抑制剂显示了对某糖厂初压汁和混合汁中的微生物菌群的抗菌效应。在对照组中,12h后观察到4.8单位的纯度降低。加入S抑制剂后,只降低2个单位。且蔗汁的稳定性在3个样品中几乎完全一致。以S抑制剂处理的蔗汁保持深褐色和清新的气味,且pH与初始相比无显著变化,而未处理的蔗汁变浅褐色,产生很强的酒味,pH和纯度显著降低。这种稳定效应尚未被其他常用的糖用杀菌剂所报导。同样,本文证明了有可能通过使用S抑制剂来稳定混合汁。经S抑制剂处理后,游离的还原物质和多聚糖比不经处理的样品低6倍。这些结果表明,形成的葡聚糖以及随之形成的游离果糖减少。 | Georgina Michelena Aidin Martinez Graciela Cerutti Monica Coronel Antonio Bell Emilia Carrera Agustin Lopez-Murguia Roberto Portuondo Lazaro Mergarejo Frost M Steele 李宜海 | 2006 | 广西轻工业2006，22，4： | 3 |
| 2 | Preparation of Rod-like Aluminum Doped Zinc Oxide Powders by Sol-gel Technique Using Metal Chlorides and Acetylacetone Precursors显示文摘Al-doped ZnO(AZO) powders were prepared by using metal chloride precursors and the sol-gel technique. IR peaks observed at 1590 cm-1 and 1620 cm^(-1) indicated the formation of metal chelate as a consequence of the addition of acetylacetone to the metal chloride solution. TG-DSC analysis of the AZO gels confirmed the formation of metal chelate as evidenced by the development of several weight loss peaks accompanied by the introduction of new endothermic peaks. The resulting AZO gels were annealed at 500, 600, and 800 ℃ to study the effect of annealing temperature. XRD and SEM results showed that crystallization of AZO gels takes place around 600 ℃. Hexagonal wurtzite structure was identified as the main phase for all the samples. In addition, small shift of the XRD(002) peak coupled with XPS results from the AZO powders confirmed the successful doping of the ZnO powders. Micron sized rod-like AZO powders were uniform in dimension and morphology and remained stable even at 800 ℃. | KESHTKAR Javad VARGAS GARCIA Jorge Roberto GALAVIZ PEREZ Jorge MARTINEZ TRINIDAD José | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，6： | 2 |

| 14 | Suppression Effects on Pineapple Soil-Borne Pathogens by Crotalaria juncea,Dolomitic Lime and Plastic Mulch Cover on MD-2 Hybrid Cultivar显示文摘The development and implementation of sustainable and environmentally friendly agricultural practices are indispensable as alternatives to pesticide use and to keep populations of soil-borne plant pathogens at levels that do not affect crop productivity.The present research evaluates the incidence of soil-borne phytopathogens on the pineapple variety MD-2,which was subjected to different treatments:Incorporation of Crotalaria juncea into the soil(organic amendment),application of dolomitic lime to soil(inorganic amendment),and the use of plastic mulch covering the soil.During the crop cycle(15 months),the following variables were evaluated:plant height(cm),fruit weight(kg·plant^(−1)),crop yield(ton·ha^(−1)),the bud root disease incidence caused by Phytophthora nicotianae,number of soil phytoparasitic nematodes and colony-forming-units(CFUs)of soil fungi and oomycetes.The results indicate that Crotalaria juncea treatment reduced the pathogen population(nematode and oomycetes)at levels that did not affect crop development,so that yield increased(18–20%).The incorporation of C.juncea into the soil as an organic amendment favors the populations of fungi disease suppressors(Trichoderma-Aspergillus).The phytoparasitic nematodes(Meloidogyne sp.,Pratylenchus sp.,and Mesocriconema sp.)and oomycetes(Phytophthora spp.,and Pythium spp.)showed a reduction of their population levels by effects of organic amendment(C.juncea).The plastic mulch was also effective,probably due to the maintenance of optimal condition to crop growth and weed control.However,the dolomitic lime application had the poorest effect under the conditions of the study area on the variables analyzed.The described observations are characteristics of a system-based approach for the potential management of soil-borne pathogens of pineapple MD-2 in Veracruz,México. | Luis Alfonso Aguilar Pérez Daniel NietoÁngel Moisés Roberto Vallejo Pérez Daniel Leobardo Ochoa Martínez David Espinosa Victoria Andrés Rebolledo Martinez Abel Rebouças São José | 2021 | Phyton-International Journal of Experimental Botany2021，90，4： | 0 |
| 15 | Pathological response to neoadjuvant therapy with chemotherapy vs chemoradiotherapy in stage III NSCLC-contribution of IASLC recommendations显示文摘BACKGROUND Neoadjuvant treatment(NT)with chemotherapy(Ch)is a standard option for resectable stage III(N2)NSCLC.Several studies have suggested benefits with the addition of radiotherapy(RT)to NT Ch.The International Association for the Study of Lung Cancer(IASLC)published recommendations for the pathological response(PHR)of NSCLC resection specimens after NT.AIM To contribute to the IASLC recommendations showing our results of PHR to NT Ch vs NT chemoradiotherapy(ChRT).METHODS We analyzed 67 consecutive patients with resectable stage III NSCLC with positive mediastinal nodes treated with surgery after NT Ch or NT ChRT between 2013 and 2020.After NT,all patients were evaluated for radiological response(RR)according to Response Evaluation Criteria in Solid Tumours criteria and evaluated for surgery by a specialized group of thoracic surgeons.All histological samples were examined by the same two pathologists.PHR was evaluated by the percentage of viable cells in the tumor and the resected lymph nodes.RESULTS Forty patients underwent NT ChRT and 27 NT Ch.Fifty-six(83.6%)patients underwent surgery(35 ChRT and 21 Ch).The median time from ChRT to surgery was 6 wk(3-19)and 8 wk(3-21)for Ch patients.We observed significant differences in RR,with disease progression in 2.5%and 14.8%of patients with ChRT and Ch,respectively,and partial response in 62.5%ChRT vs 29.6%Ch(P=0.025).In PHR we observed≤10%viable cells in the tumor in 19(54.4%)and 2 cases(9.5%),and in the resected lymph nodes(RLN)30(85.7%)and 7(33.3%)in ChRT and Ch,respectively(P=0.001).Downstaging was greater in the ChRT compared to the Ch group(80%vs 33.3%;P=0.002).In the univariate analysis,NT ChRT had a significant impact on partial RR[odds ratio(OR)12.5;95%confidence interval(CI):1.21-128.61;P=0.034],a decreased risk of persistence of cancer cells in the tumor and RLN and an 87.5%increased probability for achieving downstaging(OR 8;95%CI:2.34-27.32;P=0.001).CONCLUSION We found significant benefits in RR and PHR by adding RT to Ch as NT.A longer follow-up is necessary to assess the impact on clinical outcomes. | Diego Muñoz-Guglielmetti David Sanchez-Lorente Roxana Reyes Daniel Martinez Carmen Lucena Marc Boada Pilar Paredes Marta Parera-Roig Ivan Vollmer Joel Mases Roberto Martin-Deleon Sergi Castillo Mariana Benegas Silvia Muñoz Maria Mayoral Carla Cases Meritxell Mollà Francesc Casas | 2021 | World Journal of Clinical Oncology2021，12，11： | 0 |
