The disposal of spent activated carbon(AC) will inevitably create secondary pollution. In overcoming this problem, the spent AC can be regenerated by means of biological approach. Bioregeneration is the phenomenon in which through the action of microorganisms, the adsorbed pollutants on the surface of the AC will be biodegraded and this enables further adsorption of pollutants to occur with time elapse. This review provides the challenges and perspectives for effective bioregeneration to occur in biological activated carbon(BAC)column. Owing to very few reported works on the bioregeneration rate in BAC column, emphasis is put forward on the recently developed models of bioregeneration kinetic in batch system. All in all, providing potential solutions in increasing the lifespan of AC and the enhancement of bioregeneration rate will definitely overcome the bottlenecks in spent AC bioregeneration.

Application of a wire-guided side-viewing duodenoscope in total esophagectomy with colonic interposition

引用

World Journal of Gastroenterology 2011年第13期17卷 1787-1790页

作者： Chin-Yuan yii Jen-Wei Chou Yen-Chun Peng Wai-Keung Chow Division of Gastroenterology and Hepatology Department of Internal Medi- cine China Medical University Hospital Taichung 40447 Taiwan China Division of Gastroenterology and Hepatology Department of Internal Medicine Taichung Veterans General Hospital Taichung 40447 Taiwan China

Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is the mainstay treatment for bile duct disease. The procedure is difficult per se, especially when a side-viewing duodenoscope is used, and when the patient has altered anatomical features, such as colonic interposition. Currently, there is no consensus on the standard approach for therapeutic ERCP in patients with total esophagectomy and colonic interposition. We describe a novel treatment design that involves the use of a side-viewing duodenoscope to perform therapeutic ERCP in patients with total esophagectomy and colonic interposition. A gastroscope was initially introduced into the interposed colon and a radio-opaque standard guidewire was advanced to a distance beyond the papilla of Vater, before the gastroscope was withdrawn. A sideviewing duodenoscope was then introduced along the guidewire under fluoroscopic guidance. After cannulation into the papilla of Vater, endoscopic retrograde chol-angiography (ERC) revealed a filling defect (maximum diameter: 15 cm) at the distal portion of the common bile duct (CBD). This defect was determined to be a stone, which was successfully retrieved by a Dormia basket after complete sphincterotomy. With this treatment design, it is possible to perform therapeutic ERCP in patients with colonic interposition, thereby precluding the need for percutaneous drainage or surgery.

Expression of Six Chloroplast Genes in <i>Jatropha curcas</i>Callus under Light and Dark Conditions

引用

American Journal of Plant Sciences 2011年第5期2卷 650-656页

作者： Wilson Thau Lym Yong Cassandra Sze yii Chew Kenneth Francis Rodrigues 不详

The induction of genes encoded in the open reading frames (ORFs) of chloroplast genomes have been posited to be influenced by ambient light condition. The current study focused on determining which of the six ORFs, encoding the genes ycf 1, ycf 2, psbD (photosystem II), rbcl (Rubisco), matK (Maturase K) and rpoC1 (RNA polymerase) were influenced by light. Characterization of gene expression at the whole plant level and callus stage facilitates the identification of transcripts which are differentially regulated under these environmental conditions. Specificity of these primers was tested against genomic DNA and total RNA. Transcripts of six targeted genes were detected in all three replicates of the green and white callus under light and dark conditions, except for ycf 2 gene in green callus under light. The result showed that a partial transcript of the gene ycf 2 located on the J. curcas chloroplast genome was not detectable using reverse transcription PCR. This finding was then validated using quantitative real-time PCR. The gene was suspected to be post-transcriptionally modified. The transcripts of the remaining five ORFs could be detected using quantitative real-time PCR. Specific transcripts can be identified for application as biomarkers for selection of callus for plantlet regeneration.

This study aims to report baseline soil nutrients, specifically the organic carbon, nitrogen and phosphorus profile, in soil samples collected from Puntta Fort William on Greenwich Island in maritime Antarctic. Samples were collected along two transect lines during the early summer of 2008. Ward＇s method of hierarchical agglomerative clustering was employed to group the sampling points based on their physico-chemical properties. In this context, the soil samples can be grouped into three major clus- ters：（1） Samples with intensive biological activities, （2） samples from the area recently exposed by glacial retreat and （3） samples from barren and dried areas. Nutrient contents in Punta Fort William are driven by the intensity of biological activities as well as melt water from the Qnito glacier.

“一带一路”倡议在2013年9月提出,中国的发展同沿线国家结合,继承和发扬丝绸之路精神,创造共赢的良好合作环境,也给来华留学事业带来了新机遇。通过“一带一路”的推行,全球留学格局也发生了变化,国际留学生往中国流动的趋势发展明显。“一带一路”的建设迫切需要具备专业知识和跨文化交际能力的复合型应用人才,而来华留学生作为中国培养的重要人才资源,中国政府对来华教育事业很重视,每年向沿线国家提供大量的奖学金名额,以扩大相互间留学生规模与开展合作办学。由于倡议的支持力度大,来华留学生的数量陡升,2013年与2017年相比,来华学生增加了13万人次。中国正在高速前进的同时需要与各国建立紧密的合作关系,作为前锋的高校招生办公室要考虑如何扩大招生力度;而高校要为迎接大批入校的留学生做好准备,面对来华留学生的国别和地域跨度大,每所高校在招生、管理和教学都面临各种急待解决的难题,如:如何增加招生的力度、管理制度和人员配置、教学和教务管理工作、留学生住宿问题、留学生适应性、学习障碍等问题。论文围绕来华留学教育管理培养机制、教育教学、留学生的日常生活和适应性问题展开了论述,从现状、存在问题和解决办法进行深入研究。笔者利用自身是留学生的优势,以各国留学生为研究主体,了解目前留学生教育现状和留学生所面临的问题和适应方式。特别值得关注的是英文授课质量问题、中国政府奖学金设置的限制性问题、留学生社会适应问题。通过问题的分析来思考相应的对策,从“一带一路”倡议的角度,凸显来华留学教育的竞争优势,对来华留学生教育可持续发展提出中肯的建议,为创造更好的留学环境和拓展来华留学教育市场具有一定的意义。
