Accumulation of antibiotics in aquatic organisms poses a great threat to ecological and human health, especially because it facilitates the generation and spread of bacterial resistance. Given the diverse range of antibiotics with various features, as well as their presence at low concentrations in the environment, it is imperative to develop pretreatment techniques for antibiotics in various matrices. In this paper, the pretreatment methods proposed in recent decades for antibiotics in coastal water, sediment, and biota are summarized, with emphasis on commonly used methods such as solid-phase extraction, solid-liquid extraction, matrix solid-phase dispersion, and QuEChERS. Additionally, the potential factors influencing the extraction performance and clean-up efficiency are analyzed. The advantages and disadvantages of the methods and their development are finally discussed.   Efficacy of green nanoparticles against cancerous and normal cell lines: a systematic review and meta-analysis 期刊论文  iSwitch采集 Iet nanobiotechnology, 2018, 卷号: 12, 期号: 4, 页码: 377-391 作者:  Barabadi, Hamed;  Alizadeh, Ahad;  Ovais, Muhammad;  Ahmadi, Amirhossein;  Shinwari, Zabta Khan 收藏  |  浏览/下载：73/0  |  提交时间：2019/04/23 Reviews  Nanoparticles  Cancer  Nanomedicine  Magnetic particles  Nanomagnetics  Nanofabrication  Cellular biophysics  Bayes methods  Microorganisms  Toxicology  Antibacterial activity  Green nanoparticles  Cancerous cell lines  Normal cell lines  Review  Meta-analysis  Microbial synthesised metallic nanoparticles  Bayesian generalised linear model  Hela cancer cell lines  A549 cancer cell lines  Gram-negative bacteria  Gram-positive bacteria  Cytotoxicity  Anticancer agents  Cancer disease treatment   抗生素分析方法及其典型区域污染特征研究 学位论文  OAI收割 博士, 北京: 中国科学院研究生院, 2013 厉文辉 收藏  |  浏览/下载：169/0  |  提交时间：2014/07/09 抗生素  分析方法  污水处理厂  白洋淀  环渤海  Antibiotics  Analytical methods  Wastewater treatment plants  Baiyangdian Lake  Bohai Sea   Influence of high temperature annealing in nitrogen on upconversion luminescence of -NaYF4: Yb3+, Er3+ hexagonal sub-microplates (EI CONFERENCE) 会议论文  OAI收割 2012 International conference on Function Materials and Nanotechnology, FMN 2012, May 19, 2012 - May 20, 2012, Zhengzhou, China 作者:  Zhao J. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 The pure -NaYF4: Yb3+  Er3+ hexagonal sub-microplates were successfully prepared by the combination of coprecipitation and hydrothermal methods using sodium citrate as chelator. The size of them is about 600 nm 400 nm (side length thickness). The obtained sample was divided into two parts and one of them was annealed in nitrogen at 300 C for 2 hours. The crystal structure of the -NaYF4: Yb3+  Er3+ hexagonal sub-microplates before and after annealing treatment is hexagonal phase. Under the excitation of 980 nm diode laser  the upconversion luminescence intensity the sample after annealing is much stronger than that of the sample without annealing treatment. High temperature annealing process improved the crystallization of the sample  resulting in the decrease of the nonradiative relaxation and the enhancement of the upconversion luminescence.

A long pulse (30-50ms) 532nm laser (Fig.1) is used in our experiments with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood. Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5J-energy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin (Fig.2). Blood vessels are occluded at once and later biopsy specimens show the immediate and long-term lasting occlusion effect. While irradiating vessels directly (Fig.3)  the vessels are usually irradiated to perforate  detailed causes are still under investigation. Animal experiments show long pulse green laser therapy is a safe and effective solution to the vein's occlusion  which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.
