An improved method for the separation of the genetic variants of alpha-L-fucosidase in human semen is described. The method involves, isoelectric focusing in ultrathin-layer PAG containing a mixture of ampholines, pH 5-7 and pH 3.5-9.5, and separator HEPES. The Fu pattern obtained is simple, easy to interpret, and reproducible. The occurrence of fucosidase phenotypes in 189 semen samples from the population of Wuhan was investigated, and the frequencies of the Fu alleles were calculated. 相似文献

This article was the historical introductory lecture in the opening session of the Annual Meeting of the Polish Society of Forensic Medicine and Criminology held on 20 September 1984, in Katowice. Paolo Zacchia (1584-1659) was one of the fathers of forensic medicine and social hygiene, which were combined in his time. His work Quaestiones medico-legales is well known internationally. 相似文献

Contrary to some criticism (Musgrave and Musgrave, and West) the small group collective choice model may yield a determinate, Pareto optimal solution even with all or none bargaining. Such bargaining as well as the solution are implied by the basic assumptions of the theoretical model. 相似文献

To survive in the capitalist system (which we are still part of), we have to deal with money, and in order to keep our projects going we have to make profit. The cold principles that rule the market will often clash with our feminist ideas of humane collectivity, but I will argue that we better face these conflicts and integrate them in our work structures, because the system sneaks in anyway and finds us unprepared and fighting with each other. 相似文献

Capillary electrophoresis, the modern approach to instrumental electrophoresis, is probably the most rapidly expanding analytical technique that has appeared in recent years. In the hands of forensic toxicologists, capillary electrophoresis (CE) represents a powerful new analytical tool, which has proved suitable for the investigation of illicit drugs in seized preparations and also in complex biological matrices, among which is hair. CE can be applied according to different separation mechanisms, and among those that are toxicologically relevant are capillary zone electrophoresis and micellar electrokinetic capillary chromatography, which display different selectivities. For the investigation of hair for drugs of abuse, capillary electrophoresis proved effective, providing simultaneous determinations of different drugs without derivatization, with acceptable sensitivity (typically better than 1 ng of drug per mg of hair). The possibility of carrying out determinations of the same analytes, based on different separation mechanisms (capillary zone electrophoresis and micellar electrokinetic chromatography) with the same instrumentation, simply changing the buffer composition, provides an interesting possibility of ‘internal’ confirmation of the results. 相似文献

Principally new, simple and objective method for investigation of human hair density is suggested. Hair identity in relation to a concrete person can be confirmed or excluded by statistical processing of the results obtained. 相似文献

Detection and identification of six members of the nitrogenous hallucinogens (glycolates, benzilates and phenyl acetamides) using thin-layer and gas-liquid chromatography and mass spectrometry were attempted. The methods used are sensitive, valuable and applicable in routine forensic analyses. 相似文献
