Analysis of restriction fragment length polymorphisms in deoxyribonucleic acid (DNA) recovered from dried bloodstains

Deoxyribonucleic acid (DNA) was recovered from dried bloodstains aged up to three years and shown to be of high molecular weight. DNA was digested with restriction endonucleases and fractionated by agarose gel electrophoresis. Following transfer to a filter, DNA was hybridized with two different radioactively labeled recombinant probes which recognize highly polymorphic regions in human DNA. The autoradiographic pattern observed was not altered by sample age, and the size of the alleles was consistent with those observed in the general population. Therefore, DNA of high molecular weight prepared from dried blood samples can be used for identification.     

我国基础设施民营化进程中政府应注意的问题

基础设施主要是指关系到国民经济整体利益和长远利益的物质基础设施,主要包括公共设施,如电力、供水、供热、煤气、污水处理、城市绿化、生活垃圾和固体废弃物的收集处理工程;公共工程,如公路、大坝、灌溉及排水用渠道工程;其他交通工程,如城市交通、海港、机场等。在传统观念中,基础设施属于公共品,基础设施由政府提供是天经地义的,并且政府提供基础设施对国民经济发展全局有重大影响。而基础设施民营化是指基础设施部分或完全由私人部门提供。在基础设施领域引入竞争机制,促进私人部门进入基础设施领域,实现基础设施民营化,应该成为我国政府公用事业     

An Explanation to U.S. Politics

Fluidity of cadaveric blood after sudden death: Part II. Mechanism of release of plasminogen activator from blood vessels

Experiments by the vascular perfusion technique in isolated hind leg of the dog showed that after addition of various vasoactive drugs to the perfusate, fibrinolytic activity (plasminogen activator level) of the effluent was elevated. The effects of the drugs were completely inhibited only by the specific blocker of their receptor on the vascular wall. High K+ level of the perfusate also induced abundant release of plasminogen activator from the vascular wall.     

On the Logic of Deontic Conditionals*

Abstract. The paper outlines the approach to the analysis of deontic conditionals taken in earlier work by Jones and Pörn, compares it very briefly with two main trends within dyadic deontic logic, and then discusses problems associated with the augmentation principle and the factual detachment principle. The author then modifies Jones and Pörn's previous system, using a classical but not normal (in the sense of Chellas) deontic modality to provide the basis for an alternative analysis of deontic conditionals. This new analysis validates neither the factual detachment nor the augmentation principles. However, influenced by the approach of James Delgrande to default reasoning, the author tries to show how a restricted form of factual detachment may be accommodated within the revised system.     

Forensic-medical aspects of dermatoglyphics of the hands and feet

Issues on possibility of using capillary patterns of hands and feet in medicolegal examination of unidentified dead bodies and unknown persons, in cases of disputed paternity and maternity and child substitution are considered. Up-to-date theories on inheritance of dermatoglyphics features, their racial, sexual, age and occupational variability as well as interrelationship with some genetic diseases are analysed. Ways of researches in the field of dermatoglyphics of hands and feet for expert practice are outlined.     

Forensic pathology--Catch 22. A no-win situation(?)

The practice of forensic pathology finds itself in the unenviable position of existing in a political environment, the existence of which depends upon compromise. The professional pathologist cannot compromise ethically, morally, or legally. As a practical fact of life, most of us find ourselves in the compromising position and with the compromising attitude of "you get what you pay for." The end result all too often is tragedy for those who depend on our observations, our conclusions, our practice of medicine. What has not been widely recognized apparently is the all too common consequence of the personal jeopardy that the forensic pathologist is placed in--defenseless, friendless, disgraced, and left with a severely tarnished professional reputation.
