Validation of the use of a commercially available kit for the identification of prostate specific antigen (PSA) in semen stains 总被引:1,自引:0,他引:1

PSA is currently being used to detect and monitor quantitatively the development of prostate cancer by serum levels of PSA and has also been found to be present in high concentrations in semen. Elegantly simple, sensitive, and reproducible methods have been developed for analysis of the presence of PSA, including the Tandem-E PSA Immunoenzymetric Assay. The most common procedures for the forensic identification of semen have focused on the microscopic detection of sperm, acid phosphatase activity, and immunoelectrophoretic methods for the detection of PSA. Although these methods have been used for many years, there are problems associated with each method. The Tandem-E PSA Immunoenzymetric Assay detected PSA in 100% of the forensic casework fabric samples, 80% of the forensic casework vaginal swabs and 100% of the vasectomized individuals tested. The cut-off value was determined to be 1.77 ng/mL. These results indicate that this method can be used to identify the presence of semen in forensically significant specimens. 相似文献

Two experiments were conducted to ascertain the effects of comparative negligence on damage awards. Participants awarded damages for a mock medical malpractice case in which the level of the plaintiff's negligence was varied. Both experiments showed that damage awards were doubly discounted for partially negligent plaintiffs. Experiment 1 also found that the responses of college students did not differ from those of people who had been called for jury duty. Experiment 2 examined four components of the damage award and showed that the reduction due to the level of the plaintiff's negligence occurred only in damages for bodily harm. Implications for the judicial system are discussed. 相似文献

The relative influence of peer and parental influence on youths' use of alcohol and other drugs is explored among 446 Anglo and Hispanic youths, ages 9–17. Current users and abstainers are similar in age and gender. Among both groups, parental influence is more profound than that of peers. However, substance users, compared to abstainers, are more influenced by peers. Level of marijuana use by youths' friends is the most reliable predictor of drug use. Youths having viable relationships with parents are less involved with drugs and less influenced by drug-oriented peers.Funded by a grant (A-003-2) from the California Department of Alcohol and Drug Programs, R. H. Coombs, principal investigator.Research interests include comparative socialization patterns of adolescents and young adults in substance abuse vs. conventional careers.Research interests include domestic violence, child abuse, and substance abuse.Research interests include family interaction patterns, cross-cultural differences, and substance abuse prevention and treatment. 相似文献

The relationship between society, medicine, and the law is multi-faceted and complex. This Article examines the process of, and the influences on, the construction of fetal personhood in the legal discourses in American and Commonwealth case law and statutes. It demonstrates how the physical and visual separation of the fetus, as made possible by medical advances, has influenced the development of legal doctrine relating to the rights of the fetus. 相似文献
