Saliva and saliva-stained materials were examined as potential sources of deoxyribonucleic acid (DNA) for DNA analysis and identity testing. In this paper, the authors demonstrate that DNA was isolated and DNA banding patterns suitable for DNA typing were obtained from fresh saliva and various saliva-stained materials, such as envelopes, buccal swabs, gags, and cigarettes. Furthermore, DNA and DNA banding patterns were obtained from actual forensic evidentiary samples containing mixed saliva/semen stains. The DNA banding patterns obtained from saliva or saliva-stained material were indistinguishable from the patterns obtained from blood or hair from the same individual. Intact DNA was readily isolated and DNA banding patterns were obtained from saliva stored at -20 degrees C and dried saliva stains stored under varying conditions. We conclude that saliva and saliva-stained material can be good sources of DNA for analysis and for DNA typing in certain forensic settings. 相似文献

The "50 percent rule" is an Israeli judicial doctrine that has played a pivotal role since the early 1960s in deciding disputes between the Israeli government and Palestinian landholders under Article 78 of the Ottoman Land Code. It was first institutionalized during a government land-claiming campaign aimed at providing state land for settlement-based Judaization of Israel's predominantly Palestinian Galilee region. Two decades later, during a similar state land-claiming campaign, the doctrine diffused into the occupied West Bank. Drawing on spatial components of social science diffusion literature and work in the field of legal geography, this article offers a legal-historical-geographical analysis of the evolution and diffusion of the 50 percent rule. Its conclusions suggest a new spatialized approach to the study of legal transfers and transplants that conceptualizes law's movement across international borders as one component of a broader process of legal diffusion, in which internal diffusion also plays an important role. 相似文献
