Expert examination and assessment of state under the influence of psychoactive substances

An expert examination is a medical examination performed by a doctor on the order of a police officer or investigating judge. It includes a clinical examination of the subject, collection of samples for toxicological analysis, and the doctor's assessment of whether the subject is under the influence of psychoactive substances. The doctor requires expert knowledge, skill, experience and sufficient time to successfully perform the examination. Since the accurate assessment of the effects of psychoactive substances present depends on a comprehensive evaluation of toxicological test results, the calculation of results at the time of the event and the results of the medical examination, an unprofessionally performed examination can have far-reaching consequences, primarily legal in nature.     

京珠高速公路湖南段交通拥堵问题探究

京珠高速公路湖南段在全国高速公路交通运输中的地位重要,一旦不畅必将影响全国。近年来,随着路况不断老化、流量不断增大、严重超载货车和危险化学品运输车辆增多,加之高速公路清障施救体制不顺、装备落后,导致交通拥堵现象时有发生,防堵保畅成了亟待破解的难题。高速公路交通安全管理是一项系统工程,防堵保畅,实现人、车、路的和谐统一,必须按照“政府领导、部门联动、全民参与、整体作战”的原则,发动各政府职能部门和全社会的力量,齐心协力,齐抓共管。     

交通事故损害赔偿的法律分析

我国道路交通事故损害赔偿责任制度总体经历了三个阶段：过错责任原则;无过失责任原则或过错推定责任原则;第三者责任强制保险制度原则。但是,交通事故损害赔偿原则并非完美无缺,它在具体实施中也遇到了一些问题。建立完善的交通事故损害赔偿制度,一要制定专门的《机动车事故损害赔偿法》,二要制定完善的《机动车保险法》,三要加紧制定精神损害赔偿方面的法律、法规。     

交通事故损害赔偿归责原则的嬗变及批判

交通事故损害赔偿归责原则的不同选择对当事人的利益关系甚大。近年来,我国交通事故损害赔偿归责原则几经变更,经历了由笼统的无过错责任到过错责任,再到区分不同情形的适用过失相抵的无过错责任的演进。现行《道路交通安全法》第76条的规定较为合理,但有改进余地。     

Hair analysis for cocaine: factors in laboratory contamination studies and their relevance to proficiency sample preparation and hair testing practices

Since the introduction in 2001 of a urine-based detection method for recombinant erythropoietin (rHuEPO), transfusion-doping practices have regained interest. To address this problem, an efficient antidoping test designed to obtain direct proof of allogeneic blood transfusion was developed and validated. This test, based on flow cytometry analysis of red blood cell (RBCs) phenotypes, was used to determine the absence or the presence of numerous RBCs populations in a blood sample. A such, it may constitute a direct proof of an abnormal blood population resulting from homologous transfusion. Single-blind and single-site studies were carried out to validate this method as a forensic quality standard analysis and to allow objective interpretation of real cases. The analysis of 140 blood samples containing different percentages (0-5%) of a minor RBCs population were carried on by four independent analysts. Robustness, sensitivity, specificity, precision and stability were assessed. ISO-accredited controls samples were used to demonstrate that the method was robust, stable and precise. No false positive results were observed, resulting in a 100% specificity of the method. Most samples containing a 1.5% minor RBCs population were unambiguously detected, yielding a 78.1% sensitivity. These samples mimicked blood collected from an athlete 3 months after a homologous blood transfusion event where 10% of the total RBCs present in the recipient originated in the donor. The observed false negative results could be explained by differences in antigen expression between the donor and the recipient. False negatives were more numerous with smaller minor RBCs populations. The method described here fulfils the ISO-17025 accreditation and validation requirements. The controls and the methodology are solid enough to determine with certainty whether a sample contains one or more RBCs populations. This variable is currently the best indicator for homologous blood transfusion doping.
