小扭口藓(Barbula indica)芽胞发育特征的实验研究

在光照培养箱中人工对照培养小扭口藓(Barbulaindica(Hook. )Spreng)的芽胞,显微镜下观察并记录其发育成配子体的全过程。结果表明:小扭口藓芽胞在3 ~4d即可萌发; 10d左右开始分化出绿丝体、轴丝体及假根; 18d,轴丝体上的侧枝顶端细胞以分生缢割的方式产生单细胞或多细胞芽胞; 40d,轴丝体上开始出现配子体原始细胞;之后,配子体原始细胞发育成桑椹状的幼小配子体。还对芽胞形态发育、生理生态及配子体发生过程的特点进行了分析和讨论。，CN 23-1480/

The Cross in the City： An Anthropological View of a Church in Southeast China

本文从人类学的角度，对华南都市中一个基督教堂的生存状况进行系统考察。在此基础上认为，当代都市背景下基督教会的发展，虽然易受到都市化进程带来的诸多影响，表现出外在的、显性的一面，与此对比，隐性的历史记忆对教会产生的影响则更为深远。正是出于历史记忆的考量，教会管理人员产生“传统的教会”“回到传统”的发展定位，并将之付诸实践，对有碍“传统”的新尝试采取消极甚至禁止的态度，进而影响到教会成员尤其是年轻成员对于教会事务的参与热情，并最终影响到教会的整体发展。 本文分三部分。绪论部分介绍了选题的缘起及田野工作地的选择，同时对相关的学术史进行简要回顾，在此基础上，对研究方法包括田野工作、基本史料及文中所涉...This dissertation aims to analyse a church located in South China from the perspective of anthropology. The author considers that the development of urban churches may be affected by several factors brought on by the urbanization process. However, compared to such external influences, the impacts of historical memory is even more profound and long-term. It is this historical memory that encourages...学位：法学硕士院系专业：人文学院人类学研究所_人类学学号：1062007115181

纯净水并非理想的饮用水

该文指出纯净水在去除有机微污染、“三致”物质、病原菌、病毒和病原原生动物等物质的同时,也过多的去除了有益人体健康的适量的微量元素和矿物质。日常饮水是补充人体微量元素和矿物质的重要来源

Development of interleukin-21 as a therapeutic drug

白细胞介素21; (IL-21)是一种具有多效免疫调节活性的细胞因子,参与先天性免疫反应和适应性免疫反应的多个环节,与自身免疫性疾病、肿瘤、病毒感染等疾病的发病过; 程相关。研究表明,在动物模型中通过增强或抑制IL-21的生物学功能对多种疾病具有治疗意义,多项以重组人IL-21为受试药物的临床试验已经开展。本; 文就IL-21的生物学功能,以及IL-21作为生化药物在临床治疗中的研究进展和应用前景进行阐述。Interleukin-21 (IL-21) is a cytokine with broad pleiotropic actions that; plays an important role in both innate and adaptive immune responses.; IL-21 participates in pathogenesis processes of many diseases, such as; autoimmune disease, tumor, virus infections and so on. Enhancing or; inhibiting the activity of IL-21 has shown to have certain therapeutic; effects in animal models of a wide range of diseases. Various clinical; trials using recombinant human IL-21 as drug candidates are on-going; towards the development of IL-21 as a therapeutic drug.

Effect of Nitrate Pulse-Feeding Cultivation on Cell Growth and Cell Composition of Thermo-Tolerant Desmodesmus sp. F51

考察脉冲式添加氮源培养对耐温微藻Desmodesmus sp.; F51细胞生长和细胞组成的影响。结果表明,在脉冲式添加氮源培养过程中,藻株F51的蛋白质含量由(56016)mg/g降低至(45617)mg/g; ,而碳水化合物和油脂含量则分别由(20913)mg/g和(983); mg/g提高至(31012)mg/g和(1204)mg/g。另外,对色素和油脂的具体组成变化进行分析,发现脉冲式添加氮源培养可增强beta-胡萝; 卜素的生物合成,以及促进alpha-胡萝卜素生物转化为叶黄素,同时还可发现叶黄素积累与多不饱和脂肪酸含量变化呈正相关性。而在碳水化合物的具体组成; 分析中,发现碳水化合物为藻株F51主要的储能物质,当脉冲式添加氮源培养时间为3; d时,其葡萄糖占总碳水化合物的质量分数可明显提高至(75.71.4)%。采用脉冲式添加氮源培养策略可明显同时促进藻株F51叶黄素和碳水化合物的生; 产。The aim of the present study was to investigate the effect of nitrate; pulse feeding on the cell growth and cell composition of Desmodesmus sp.; F51. Under nitrate pulse-feeding cultivation, the protein content of; cells of Desmodesmus sp. F51 decreased from(560 16) mg/g to(456 17); mg/g, while the contents of carbohydrate and lipid increased from(209 ; 13) mg/g to(310 12) mg/g and(98 3) mg/g to(120 4) mg/g, respectively.; By investigating the changes in carotenoid, lipid and carbohydrate; compositions, it appeared that nitrate pulse feeding could promote; beta-carotene biosynthesis and enhance the bioconversion of; alpha-carotene to lutein. Lutein accumulation was positively associated; with polyunsaturated fatty acid formation. Desmodesmus sp. F51 tended to; accumulate carbohydrate as an energy storage product after 3 days of; cultivation under nitrate pulse-feeding conditions, and the major; accumulated monosaccharide was glucose(75.7 1.4)%. Therefore, the; nitrate-pulse feeding strategy is a highly promising approach to; simultaneously produce lutein and carbohydrate in Desmodesmus sp.
