A modification of the microplate method for reverse ABO typing of bloodstains and additional validation studies

The results of additional validation studies of a sensitive microplate hemagglutination assay for ABO reverse grouping of bloodstains are presented. The results of the validation study demonstrate the reliability of the microplate assay for use in routine serological casework. Based on these studies, the microplate assay has now replaced the Lattes crust test for ABO reverse grouping of bloodstains in the FBI Laboratory.     

Acidic and neutral drugs screen in blood with quantitation using microbore high-performance liquid chromatography–diode array detection and capillary gas chromatography–flame ionization detection

Blood previously acidified with aqueous saturated ammonium chloride solution was extracted with ethyl acetate. The dried extract was subjected to acetonitrile–hexane partition. The acetonitrile portion was analysed for the presence of acidic and neutral drugs by HPLC–DAD (200 mm×2.1 mm I.D. microbore ODS-Hypersil column) and GC–FID (25 m narrow-bore×0.25 mm I.D. HP-5 column with 0.33 μm film thickness). The protocol was found to be suitable for both clinical toxicology (including emergency toxicology) and postmortem toxicology. At least 66 drugs of interest were unequivocally identified by RRTs (HPLC) and UV spectra (DAD) match while another 12 were unequivocally identified by double RRTs match (HPLC and GC). Quantitation was facilitated by incorporating calibration blood standards in each assay batch. The five drugs most commonly encountered in clinical blood specimens (1150 cases) were: paracetamol (47.4% of the cases); chlormezanone (6.6%), theophylline (1.74%), naproxen (1.65%) and mefenamic acid (1.56%). The following drugs were detected in toxicologically significant quantities in postmortem blood specimens (245 cases): phenobarbitone (1.22% of the cases), naproxen (0.82%), chlormezanone (0.82%), theophylline (0.82%), carbamazepine (0.41%) and paracetamol (0.41%).     

科学技术与社会主义

社会主义和科学技术是 19世纪以来两股最活跃的力量 ,它们在本质上是一致的。科学技术是推动历史前进的巨大杠杆 ,它推动了资本主义的进一步发展 ,社会主义的发展也迫切需要科技 ,同时科学技术的发展也需要合理的社会环境 ,社会主义能够创造科技。社会主义和科学技术的紧密结合和互动作用 ,既将使社会主义得到巩固乃至在全世界取得胜利 ,也将使科学技术的发展进入一个崭新的天地。     

《毛泽东思想概论》中"两个建议"的史实质疑与论证

我国高等院校党史教材和国内诸多史书论著,普遍认定“毛泽东思想两个建议”的史实。通过对《毛泽东思想概论》、《彭德怀自述》等有关“两个建议”史实不同版本的比较论证分析,可得出“中央革命根据地第五次反‘围剿’战役后期的两个战略性建议,不是毛泽东提出来的”史实结论,否定国内史学界近半个世纪以来所认定的普遍观点。     

Understanding Recreation and Sport as a Rehabilitative Tool Within Juvenile Justice Programs

This article discusses relevant literature on the potential benefits of sport, recreation, and leisure, and how these benefits relate to rehabilitation of juveniles. Many professionals involved in juvenile rehabilitation believe sport and recreation are beneficial adjuncts to treatment programming; however, it can be difficult to structure sport and recreation in ways that directly correspond to treatment goals. The purpose of this article is to provide insights for professionals working with juveniles on how sport and recreation programming can be an effective means of helping to achieve rehabilitation goals. Attention is given to approaches, particularly the Teaching Games for Understanding model (Bunker & Thorpe, 1982), which can be used to effectively link recreation and sport to the rehabilitation process.
