信息检索第二次实习作业

利用工农业废水开发微生物发酵培养基及其应用研究
工农业生产发展迅速,同时也出现了制约发展的两大因素,即资源短 缺和环境污染。我国资源短缺且有限资源不能高效利用;环境污染,尤 其是水体污染日益加剧,严重阻碍了生产发展,影响了生活。工农业生 产中产生的废水是主要的污染源之一,如啤酒、味精发酵废水,沼气发 酵废液等。生产啤酒和味精的原料主要是谷物类淀粉、蛋白质、氨基酸 等。其产生的废水中含有大量的淀粉、植物蛋白和氨基酸等营养物质?, 沼液中也含有丰富的营养元素,如按过去采用机械、物理和化学的方法 处理这些废水,不但成本高、难处理、达不到排放标准而污染环境,还 不能充分利用其中的营养物质,造成浪费。在利用废水培养微生物进而 处理废水方面国内有一些研究报道。有人在利用啤酒废水养殖螺旋藻]、 培养单细胞蛋白(SCP) 方面作过尝试;在利用味精废水培养微生物方 面主要集中在培养、驯化苏云金芽孢杆菌(Bacillus thudngienzis)菌 株,达到既处理废水又生产生物农药的目的;利用沼液培养微生物并发 酵生产生物农药目前尚未见报道。

信息检索 第二次作业答案 南通大学

一、利用搜索引擎来查找以下资料,简要写出检索步骤(包括你选用的检索工具和检索 词) 1、请查出自己的姓氏起源分布并介绍一位同姓的历史名人。
“张”的姓氏起源: 张姓是中国最大的姓之一,得姓历史悠久,族大支繁。
1999 年我国在昆明举办“世 界园艺博览会” ,世博园内立了《源于河南的姓氏》碑。
其中,第三位便是“张姓源于 濮阳” 。
张姓曾有 43 个望族,为百家姓之首。
张姓,具有三个明显的特点,一是得姓较 早,源远流长;二是族大支繁,遍及全国,到处都有张氏族人;三是人才辈出,不可胜 数,从古至今,历代皆有张氏的杰出人物,像张衡、张仲景、张謇、张澜等人为中华民 族的繁荣昌盛贡献着力量。
关于张姓的始祖,历代史书中有如下记载: “黄帝第五子清阳之孙生挥,为弓正, 观弧星始制弓矢,主祀弧星,因姓张氏” (见《元和姓纂》“挥造弧矢,受封于张,后 ) 为弓氏。
张,望出濮阳。
” “张姓出于姬姓,至周而氏者祖于韩,其得望者十二,曰襄阳,洛阳,河东,始兴, 冯翊,吴郡,平原,青河,河间,中山,曰魏,曰蜀。
(见袁桷《张氏宗谱序》 ” ) 从以上记载看,张姓之源,可追溯到五千年前中华民族的共同始祖黄帝,是黄帝的 直系后裔。
黄帝第五子青阳,生子曰挥。
这位叫挥的黄帝之后,正是张姓的始祖。
所以 说张姓是黄帝的直系后裔,有一定道理。
这位名挥的黄帝后裔,非常聪明,他观看到天上的弧星,便仿其形状做了弓矢。
原 来,天上有星名“天弓” ,简称“弧” ,属井宿,共九星,在天狼星东南。
八星如弓形, 外一星像矢,在犬犬、南船两星座内。
《宋史·天文志》载: “弧矢九星在狼星东南, 天弓也” 。
挥看到“天弓” ,由“天弓”之形受到启发,最早发明了弓矢这个古代重要的 武器。
他也由此而被 “赐姓张氏” 。
不过,当初的“张”“非命姓氏之义也 ” , 。
因为弓矢发明之后,在使用之前,必须 先用力气将弓张开,不然,就无法使用。
挥是因为这个缘故而命为“张氏”的。

The antioxidant activities of ethanolic crude extract (ECE) and its four different solvent sub-fractions (namely, petroleum ether fraction (PEF), ethyl acetate fraction (EAF), n-butanol fraction (BF) and the aqueous fraction (AF) from the receptacles of Nelumbo nucifera Gaertn. (Receptaculum Nelumbinis) were investigated using two in vitro antioxidant assays. BF showed the highest total phenolic content (607.6 mg/g gallic acid equivalents), total flavonoid content (862.7 mg/g rutin equivalents) and total proanthocyanidin content (331.0 mg/g catechin equivalents), accompanied with the highest antioxidant activity compared to other fractions through 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical scavenging assays. Five flavonol glycosides, namely hyperoside (1), isoquercitrin (2), quercetin-3-O-β-d-glucuronide (3), isorhamnetin-3-O-β-d-galactoside (4) and syringetin-3-O-β-d-glucoside (5) were isolated from the Receptaculum Nelumbinis. Compounds 2-5 were isolated for the first time from the Receptaculum Nelumbinis. The five isolated flavone glycosides, particularly compounds 1-3, demonstrated significant DPPH and ABTS radical scavenging activity, with IC(50) values of 8.9 ± 0.2, 5.2 ±0.2, 7.5 ±0.1 for DPPH and 114.2 ±1.7, 112.8 ±0.8, 172.5 ±0.7 μ g/mL for ABTS, respectively. These results suggest that Receptaculum Nelumbinis has strong antioxidant potential and may be potentially used as a safe and inexpensive bioactive source of natural antioxidants.

In vitro antioxidant activities of endophytic fungi isolated from the liverwort Scapania verrucosa.2Zeng PY, Wu JG, Liao LM, Chen TQ, Wu JZ, Wong KH. Academy of Integrative Medicine, Fujian University of Traditional Chinese Medicine, Fuzhou, China. We investigated in vitro antioxidant activities of 49 endophytic fungi isolated from the liverwort Scapania verrucosa. Based on morphological and molecular identification, the endophytic fungi isolated were classified into seven genera (Hypocrea, Penicillium, Tolypocladium, Chaetomium, Xylaria, Nemania, and Creosphaeria), all belonging to one family (Xylariaceae). By screening with the 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) decolorization assay, the ethyl acetate extracts of five endophytic fungi (T7, T21, T24, T32, and T38 strains), which exhibited remarkable Trolox equivalent (TE) antioxidant capacity (ranging from 997.06 to 1248.10 μmol TE/g extract), were selected and their antioxidant capacity was further evaluated by assays for 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, hydroxyl radical scavenging, reducing power, and ferrous ion chelating. The ethyl acetate extracts of two endophytic fungi (T24 and T38) were found to have comparable scavenging abilities on both DPPH-free radicals (93.9 and 88.7%, respectively, at 50 μg/mL) and hydroxyl radicals (97.1 and 89.4%, respectively, at 2 mg/mL) when compared with those of the positive controls (ascorbic acid and butylated hydroxytoluene, respectively). Although their reducing powers were similar to that of butylated hydroxytoluene, as indicated by absorbance (0.35 and 0.30 at 50 μg/mL, respectively), only the T38 strain's ethyl acetate extract showed ferrous ion chelating ability (92.9% at 1 mg/mL) comparable to that of the EDTA-2Na control. These endophytic fungi in S. verrucosa are a potential novel source of natural antioxidants. PMID: 22194173 [PubMed - indexed for MEDLINE] 3. Molecules. 2010 Jan 8;15(1):241-50. Effects of volatile components and ethanolic extract from Eclipta prostrata on proliferation and differentiation of primary osteoblasts. Lin XH, Wu YB, Lin S, Zeng JW, Zeng PY, Wu JZ. Academy of Integrative Medicine, Fujian University of Traditional Chinese Medicine, Fuzhou, Fujian 350108, China. Eclipta prostrata, an aromatic plant, is known in Chinese herbal medicine for the treatment of various kidney diseases. In the present study, the volatile components were isolated from the aerial parts of this plant by hydrodistillation and analysed by GC-MS. A total of 55 compounds, which were the major part (91.7%) of the volatiles, were identified by matching mass spectra with a mass spectrum library (NIST 05.L). The main components were as follows: heptadecane (14.78%), 6,10,14-trimethyl-2-pentadecanone (12.80%), n-hexadecanoic acid (8.98%), pentadecane (8.68%), eudesma-4(14),11-diene (5.86%), phytol (3.77%), octadec-9-enoic acid (3.35%), 1,2-benzenedicarboxylic acid diisooctyl ester (2.74%), (Z,Z)-9,12-octadecadienoic acid (2.36%), (Z)-7,11-dimethyl-3-methylene-1,6,10-dodecatriene (2.08%) and (Z,Z,Z)-1,5,9,9-tetramethyl-1,4,7-cycloundecatriene (2.07%). The effects of3volatile components and ethanolic extract from the aerial parts of this plant on the proliferation and differentiation of primary osteoblasts were evaluated by the MTT method and measuring the activity of alkaline phosphatase (ALP activity). Both volatile components and ethanolic extract (1 microg/mL to 100 microg/mL) significantly (p < 0.01) stimulated the proliferation and increased the ALP activity of primary osteoblasts. These results propose that E. prostrata can play an important role in osteoblastic bone formation, and may possibly lead to the development of bone-forming drugs.

Wu YB, Zheng CJ, Qin LP, Sun LN, Han T, Jiao L, Zhang QY, Wu JZ. Department of Pharmacy, Fujian University of Traditional Chinese Medicine, Fuzhou, Fujian, PR China. wxsq1@ Bioactivity-guided fractionation led to the successful isolation of antiosteoporotic components, i.e. physicion (1), rubiadin-1-methyl ether (2), 2-hydroxy-1-methoxy- anthraquinone (3), 1,2-dihydroxy-3-methylanthraquinone (4), 1,3,8-trihydroxy-2-methoxy- anthraquinone (5), 2-hydroxymethyl-3-hydroxyanthraquinone (6), 2-methoxyanthraquinone (7) and scopoletin (8) from an ethanolic extract of the roots of Morinda officinalis. Compounds 4-8 are isolated for the first time from M. officinalis. Among them, compounds 2 and 3 promoted osteoblast proliferation, while compounds 4, 5 increased osteoblast ALP activity. All of the isolated compounds inhibited osteoclast TRAP activity and bone resorption, and the inhibitory effects on osteoclastic bone resorption of compounds 1 and 5 were stronger than that of other compounds. Taken together, antiosteoporotic activity of M. officinalis and its anthraquinones suggest therapeutic potential against osteoporosis. PMID: 19169204 [PubMed - indexed for MEDLINE] 5.

Department of Pharmacy, Fujian University of Traditional Chinese Medicine, Fuzhou, Fujian Province 350003, China. OBJECTIVE: To investigate the anti-inflammatory effect of casticin of Fructus Viticis. METHODS: Observations were made on the anti-inflammatory effect of casticin in the models of acute inflammation in vivo. RESULTS: Casticin inhibited significantly xylene-induced mouse ear edema, egg albumen-induced rat paw edema and acetic acid-induced mouse vascular permeability. CONCLUSION: Casticin has significant anti-inflammatory effect on acute inflammation, which is probably related to the inhibition of the inflammation factors. Casticin is the effective constituent contributing to the4anti-inflammatory effect of Fructus Viticis. PMID: 17854563 [PubMed - indexed for MEDLINE] 6.

三、web of science 检索平台包含哪三大引文索引?JCR是什么?
答:Basic Search,Cited Reference Search,Advanced Search
JCR是ISI每年出版《期刊引用报告》,在报告中,JCR对8000多种期刊之间的引用和被引用数据进行统计、运算,并针对每种期刊定义了影响因子等指数加以报道。
一种刊物的影响因子越高,也即其刊载的文献被引用率越高,一方面说明这些文献报道的研究成果影响力大,另一方面也反映该刊物的学术水平高。
因此,JCR以其大量的期刊统计数据及计算的影
响因子等指数,而成为一种期刊评价工具。
图书馆可根据JCR提供的数据制定期刊引进政策;论文作者可根据期刊的影响因子排名决定投稿方向。
