| 1 | 植物对土壤重金属富集特性研究进展显示文摘植物修复是土壤重金属污染修复的有效手段之一,其修复过程、影响因素及机理已经得到广泛研究。明确植物富集重金属过程中的影响因素,诱导提高植物修复能力是提高植物修复重金属污染效果的关键。本文在总结国内外研究现状的基础上,对植物富集重金属的特性和影响植物富集的因素以及对植物富集重金属的评价指标进行了综述。 | 周晓声 娄厦 Larisa Dorzhievna Radnaeva Elena Nikitina 汪豪 | 2022 | 生态毒理学报2022，17，3： | 9 |
| 2 | Preventive effect of a pectic polysaccharide of the common cranberry Vaccinium oxycoccos L. on acetic acid-induced colitis in mice显示文摘AIM: To study isolation and chemical characterization of pectin derived from the common cranberry Vaccinium oxycoccos L. (oxycoccusan OP) and the testing of its preventive effect on experimental colitis.METHODS: Mice were administrated orally with OP two days prior to a rectal injection of 5% acetic acid and examined for colonic damage 24 h later. Colonic inflammation was characterized by macroscopical injury and enhanced levels of myeloperoxidase activity measured spectrophotometrically with o-phenylene diamine as the substrate. The mucus contents of the colon were determined by the Alcian blue dye binding method. Vascular permeability was estimated using 4% Evans blue passage after i.p. injection of 0.05 mol/L acetic acid. RESULTS: In the mice treated with OP, colonic macroscopic scores (1.1 ± 0.4 vs 2.7, P < 0.01) and the total square area of damage (10 ± 2 vs 21 ± 7, P < 0.01) were significantly reduced when compared with the vehicle-treated colitis group. OP was shown to decrease the tissue myeloperoxidase activity in colons (42 ± 11 vs 112 ± 40, P < 0.01) and enhance the amount of mucus of colitis mice (0.9 ± 0.1 vs 0.4 ± 0.1, P < 0.01). The level of colonic malondialdehyde was noted to decrease in OP-pretreated mice (3.6 ± 0.7 vs 5.1 ± 0.8, P < 0.01). OP was found to decrease the inflammatory status of mice as was determined by reduction of vascular permeability (161 ± 34 vs 241 ± 21, P < 0.01). Adhesionof peritoneal neutrophils and macrophages was also shown to decrease after administration of OP (141 ± 50 vs 235 ± 37, P < 0.05).CONCLUSION: Thus, a preventive effect of pectin from the common cranberry, namely oxycoccusan OP, on acetic acid-induced colitis in mice was detected. A reduction of neutrophil infiltration and antioxidant action may be implicated in the protective effect of oxycoccusan. | Sergey V Popov Pavel A Markov Ida R Nikitina Sergey Petrishev Vasily Smirnov Yury S Ovodov | 2006 | World Journal of Gastroenterology2006，12，41： | 9 |
| 3 | 基于随机森林特征变量优化的湿地植物分类与密度反演显示文摘以长江口滨海湿地为研究区域,采用随机森林算法对滨海湿地植被进行分类。在提取Landsat-8 OLI影像植被指数和水体指数的基础上,提出利用植被指数季节差值对模型进行特征变量优化,分析了长江口滨海湿地植物群落分布的空间特征。以所占面积最大的互花米草(入侵物种)为例,采用多元线性回归模型结合实地测量数据,估算了秋季的互花米草植物密度的空间特征。提出的多时相遥感数据结合随机森林特征变量优化方法,可以较为便捷地提取长江口湿地3种优势物种的空间分布特征,与最大似然法相比,分类精度有较大提高,总体分类精度由78.35%提高至87.55%,Kappa系数由0.72提高至0.84。该方法适用于存在“异物同谱”问题的湿地植物群落研究。 | 刘曙光 董行 娄厦 DORZHIEVNA Radnaeva Larisa NIKITINA Elena | 2021 | 同济大学学报(自然科学版)2021，49，5： | 8 |
| 4 | 长江口近岸地区抗生素抗性基因与微生物群落分布特征显示文摘由于抗生素的大量使用,环境中微生物对抗生素的抗性不断增加,抗生素抗性基因(ARGs)问题越来越严重,严重威胁生态安全和人类健康.为研究长江口近岸地区水体和底泥沉积物中的ARGs和微生物群落的分布特征,通过野外调查采集了8个站点的水样和沉积物样本,对2种磺胺类抗性基因(sul1、sul2)、6种四环素类抗性基因(tetM、tetC、tetX、tetA、tetO、tetQ)、1种整合子基因intI1、16S rRNA基因和微生物群落进行检测分析.结果表明,长江口近岸地区10种抗性基因的检出率为100%.其中,整合子基因intI1和水样中多种ARGs呈显著正相关关系.变形菌门(Proteobacteria)和拟杆菌门(Bacteroidota)是长江口近岸地区水环境中的优势菌门;Chloroplast为水体中的主要菌属,Chloroplast和Nitrospira为沉积物中的主要菌属.在水体中,硝化螺旋菌门(Nitrospirota)是4种四环素类抗性基因(tetX、tetA、tetO和tetQ)共同的潜在宿主;在沉积物中,Sva0485是sul1和intI1的共同潜在宿主.微生物群落的分布是长江口近岸地区ARGs迁移转化的重要影响因素. | 徐秋鸿 刘曙光 娄厦 Larisa Dorzhievna Radnaeva Elena Nikitina Makhinov Aleksei Nikolavich Araruna José Tavares 金宇辰 李鑫 | 2023 | 环境科学2023，44，1： | 8 |

| 10 | 二语交际意愿的影响因素及其培养途径显示文摘二语交际意愿是影响学生使用第二语言进行交际的重要变量,是某一个体在一定时间与特定对象使用二语进行交流的意向状态。二语交际意愿不仅受交际人性格、动机、羞怯、焦虑等心理因素的影响,还受到交际场合、交际双方的熟悉程度、自我感知交际能力、交际者个人情感、认知等情境性因素的制约。二语教师应通过帮助学生克服羞怯心理,降低交际焦虑,增强学生交际安全感和责任心来提高学生的交际意愿,实现二语教学的交际功能和社会功能。 | Lan Guoxing Larisa Nikitina Woo Wai Sheng | 2020 | 现代交际2020，，8： | 1 |
