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.     

习近平新时代文明观的理论程式与实践指向——兼驳美国政客的“文明冲突论”

习近平新时代文明观是习近平新时代中国特色社会主义思想的"人类文明篇章"。从文明向度回答了"世界怎么了",批驳了当前以美国为主要代表的文明中心主义,以及全球恐怖主义、民粹主义等野蛮行径,指出人类文明面临主体性下降的共同挑战。从世界视野回答了"我们怎么办",是马克思主义文明观的创新发展,是中华民族文明叙事逻辑的当代延展,堪称全球化历史时代的精神精华。从自身定位回答了"中国如何做",为中国推动文明交流互鉴提供了根本遵循与行动指南。习近平新时代文明观的"出场""在场""现场"既构成了逻辑完备的理论程式,有力驳斥了文明冲突论,又具有鲜明的实践指向,领航中国特色大国外交。     

利益相关者还是对手?--解读美国国防部四年防务评估报告

2006年2月3日,美国国防部在其官方网站上提前公布了新版<四年防务评估报告>(原定于2月6日提交国会),由于这是决定未来数年、乃至更长一段时间美国国防政策和军事战略走向的纲领性文件,因而受到了世界各国的广泛关注.     

论行政司法裁判权

行政司法裁判权的核心在于将司法机关(法院)作为一道屏障,矗立在代表公共权利的行政机关和享有私人权利的行政相对人之间,运用司法权力监督行政权力,并籍此给遭受行政权力侵犯的公民、法人和其他组织提供救济。在我国,行政司法裁判权存在许多局限,如何真正实现法律意义上的行政司法裁判权,将是我国民主与法制建设的一个重要标志。     

职业道德建设浅谈

职业不道德现象作为一种群体行为,突出反映在垄断行业,并开始引起人们的广泛注意。加强职业道德建设,必须首先从确立职业道德的价值取向入手,而后科学地制定职业道德规范,并遵循平等与公正原则,可操作性、强制性原则,以及合法性原则。     

薛幕桥与《薛暮桥回忆录》

从在“牢监大学”自学成才到三十年代主编《中国农村》，从在新四军和苏北抗大讲授政治经济学到主持山东解放区的战时财经工作，从建国前夕在西柏坡协助周恩来同志处理即将诞生的新中国的经济工作到为建立社会主义市场经济体制而深入探索，薛暮桥以其睿智的头脑、深邃的思想、精辟的论述，将马克思主义经济理论运用于中国革命和建设的实践，提出了一系列富有创建性的政策主张，为中国的社会主义经济改革与发展作出了重要贡献，从而成为我国经济学界的泰斗、杰出的马克思主义经济学家、新中国社会主义经济理论的奠基人之一。１９０４年，薛暮…     

Spatial variation of refractive index in a pane of float glass.

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.     

Sudden death in angiodysplasia of the gastroesophageal junction.

A 22-year-old Korean soldier, who had received blows to the neck and epigastrium from an officer 10 h earlier, suddenly died after massive hematemesis. He had been in relatively good health except for episodes of blood-tinged vomiting approximately 5 and 7 months prior to this event. Postmortem examination revealed angiodysplasia involving the gastroesophageal junction, and the stomach was distended with blood. No abnormal findings were present around the whole viscera, and the duodenum was free of blood. The pathologic significance of upper gastrointestinal angiodysplasia as a potential source of bleeding and a chronologic correlation between the trauma and bleeding are discussed.
