Mitochondrial DNA cytochrome oxidase I gene: potential for distinction between immature stages of some forensically important fly species (Diptera) in western Australia

Forensic entomology requires the fast and accurate identification of insects collected from a corpse for estimation of the postmortem interval (PMI). Identification of specimens is traditionally performed using morphological features of the insect. Morphological identification may be complicated however by the numerical diversity of species and physical similarity between different species, particularly in immature stages. In this study, sequencing was performed to study the mitochondrial DNA (mtDNA) as the prospective basis of a diagnostic technique. The sequencing focused on a section of the cytochrome oxidase I encoding region of mtDNA. Three species of calliphorid (blow flies) commonly associated with corpses in western Australia, Calliphora dubia, Chrysomya rufifacies and Lucilia sericata, in addition to specimens of Calliphora augur and Chrysomya megacephala were studied. Phylogenetic analysis of data revealed grouping of species according to genus. The DNA region sequenced allowed identification of all species, providing high support for separation on congeneric species. Low levels of variation between some species of the same genus however indicate that further sequencing is required to locate a region for development of a molecular-based technique for identification.     

State of the art of guidelines

Guidelines have existed in medicine for many centuries. Galen's doctrine of laudable pus sent many to an early grave, but variance in treatment put the practitioner in a difficult position, especially if all did not go well. Currently, guidelines proliferate, allegedly based upon careful evaluation of evidence culled from a variety of sources. However, obedience to guidelines is variable internationally and nationally, thus raising questions about their enforceability. They are, of course, not legally enforceable, but courts may be influenced by them, and variation must be evidence-based. Guidelines cannot logically be regarded as being set in stone; if that were the case, then there could be no innovation and medicine would not advance.     

An empirical study of tissue banking in Australia: navigating regulatory and ethical challenges

Collections of tumour samples can be an invaluable resource for medical research. There are, however, numerous ethical and legal challenges associated with tumour banking. While there has been extensive discussion of these issues in the legal and ethical literature, there are few available empirical data in relation to the activities of tumour banks in Australia, their practices around ethically charged issues, and their success in implementing complex regulatory guidelines. The aim of this study was to gain more information about the activities of tumour banks in New South Wales, Australia, with a particular focus on their management of, and attitudes towards, ethical and regulatory issues. A survey of 27 tumour collection and research facilities was conducted using a 55-item questionnaire. There is significant heterogeneity of research methodologies as well as of methods for gaining consent and ensuring donor privacy, and there is general concern among the research community about ethical and regulatory issues related to tumour banking. Heterogeneity of practice and uncertainty about ethical and regulatory requirements is problematic in its potential to hinder research and its potential to generate the space for unethical practice, whether intentional or unintentional. There is a pressing need to address these issues so that tumour banks can be used in the most ethical and efficient way possible.     

Social Security preclusions in personal injury litigation

This editorial scrutinises the impact of preclusion periods for social security entitlements upon personal injury practice. It identifies the differences in calculation in respect of the compensation part of lump sum payments, depending upon whether a plaintiff's case is settled or resolved by litigation. It examines the effect of s 1184K of the Social Security Act 1991 (Cth) and the circumstances in which the discretion to reduce or waive the preclusion period has been exercised in favour of recipients of lump sum payments. It argues that room remains for creative arguments on behalf of plaintiffs, highlighting the potential for the compensatory effect of the lump sum to be undercut if the preclusion provisions are fully applied.

Taiwan's Foreign Policy and Africa: The limitations of dollar diplomacy

The search for status, or more correctly, the desire to maintain status, lies at the heart of the Republic of China on Taiwan's (ROC) foreign policy. This is particularly so vis-a ¤ -vis its official state-to-state relations. In this regard, the ROC has been constrained by a conscious policy by the People's Republic of China (PRC) to try and marginalize Taiwan on the international stage. Due to objective realities, Taiwan has had to become satisfied with maintaining official state relations with small states only. All, with the exception of the Vatican, are in the developing world, with a number in Africa. This paper examines Taiwanese foreign policy and its diplomatic initiatives, with particular reference to its use of 'dollar diplomacy' in its activities in Africa. The constraints and limitations of such policies are drawn out.
