Optimization of Human mtDNA Control Region Sequencing for Forensic Applications

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.     

Property and the human body: a proposal for posthumous conception

There is no greater error in law and bioethics than the continuing opposition to applying the concept of property to posthumous conception cases and the human body generally. The aim of this article is to challenge this error and the assumptions underpinning it. The language of property, conceived of as a "web of interests", can be used to capture and identify the social, moral and ethical concerns that arise in cases concerning the human body, a position that finds support from a correct reading of the early High Court of Australia's decision in Doodeward v Spence (1908) 6 CLR 406. However, a key issue on which the language of property is silent is how to quantify the various competing interests in the posthumous conception case: the concept is useful only insofar as it provides the device for capturing the entirety of the posthumous conception problem.
