A novel method for cyanide quantification in human whole blood using ion chromatography with amperometric detection and its application to cyanide intoxication cases

Cyanide is a highly toxic agent that has been frequently used for suicide in South Korea. It is also used in various industrial fields, such as metal plating, in which many accidental cyanide intoxications have occurred. To overcome the disadvantages of conventional cyanide analysis methods, a simple and fast method for the analysis of cyanide in whole blood using ion chromatography (IC) with amperometric detection was developed in this study. Whole blood samples were deproteinized, diluted, and analyzed using an IC–amperometric detection system. The limits of detection and quantitation were 0.1 and 0.2 mg/L, respectively. The method showed good linearity in the range of 0.2 to 50 mg/L with R² > 0.99. The intra- and inter-assay precision and accuracy values were <10%. The established method was successfully applied to analyze whole blood samples from three cyanide intoxication cases.     

New Zealand lawyers and conveyancers disciplinary tribunal cases involving vulnerable clients, 2011–2017*

ABSTRACT

This research analyses disciplinary decisions of the New Zealand Lawyers and Conveyancers Disciplinary Tribunal (NZLCDT) from 2011 to 2017 that involve vulnerable clients. Increasingly, scholarship discusses vulnerability as an ethical concept, including in the legal context. Based on published decisions, the present study inquires whether some legal clients’ vulnerability warrants special attention. Twenty-five of the 193 clients in the NZLCDT decisions qualified as vulnerable based upon age, gender, mental health/neuro-disability or immigrant status. The results may inform disciplinary bodies and inspire preventive strategies by lawyers, educators and regulatory bodies. Ultimately, this evidence-based analysis magnifies the importance of client-centred approaches to risk reduction in legal practice.

对走中国特色的科技创新之路的几点思考

走具有中国特色的科技创新之路,要有合理健全的体制.其市场体制既要有竞争压力,又要保护创新者利益;其科技体制要保证企业是创新的主体,政府搞好宏观调控和服务,营造公平竞争的创新环境.投资上要由政府主导型向民间主导型转变,加大基础研究经费和投资强度;在技术引进和技术自创关系上,要有选择地引进,并在分析消化吸收基础上再创新,提高自主创新能力.     

广东省群体性事件多发的态势与防范对策

广东省群体性事件的高发是广东省处于社会转型时期的必然产物。社会发展的断裂、利益表达机制的缺乏、群体利益冲突的增加是群体性事件多发的根本原因。建立健全社会保障机制、利益表达机制、社会危机应对机制、全面的社会治安防控机制是解决群体性事件的有效措施。     

加大对成都中小企业政策扶持力度的思考

任何国家和地区的中小企业要得以健康的发展都离不开政府的支持和扶植。在市场经济条件下,作为承担宏观经济管理任务的政府对中小企业的支持,不是直接插手创办企业或干预企业的生产经营,而是从本国或本地区的实际出发,逐步建立和形成有利于中小企业健康发展的政策体系。本文从成都的实际出发,从加大对成都中小企业政策扶持力度的角度,提出了一些建议和意见。
