Guidelines and considerations for conducting experiments using tissue microarrays

Tissue microarrays (TMAs) represent a powerful method for undertaking large-scale tissue-based biomarker studies. While TMAs offer several advantages, there are a number of issues specific to their use which need to be considered when employing this method. Given the investment in TMA-based research, guidance on design and execution of experiments will be of benefit and should help researchers new to TMA-based studies to avoid known pitfalls. Furthermore, a consensus on quality standards for TMA-based experiments should improve the robustness and reproducibility of studies, thereby increasing the likelihood of identifying clinically useful biomarkers. In order to address these issues, the National Cancer Research Institute Biomarker and Imaging Clinical Studies Group organized a 1-day TMA workshop held in Nottingham in May 2012. The document herein summarizes the conclusions from the workshop. It includes guidance and considerations on all aspects of TMA-based research, including the pre-analytical stages of experimental design, the analytical stages of data acquisition, and the postanalytical stages of data analysis. A checklist is presented which can be used both for planning a TMA experiment and interpreting the results of such an experiment. For studies of cancer biomarkers, this checklist could be used as a supplement to the REMARK guidelines.

Screening-detected non-symptomatic breast cancer: a case history

Alice is a 65 year-old woman who was recalled for further investigations following a routine screening mammogram, which showed a 25 mm mass in her left breast. This case history will report on the further investigations and surgery required to manage this infiltrating ductal carcinoma. The histopathology report will be analysed to provide a rationale for future treatment with radiotherapy, and Alice's expected prognosis will be presented using the Nottingham Prognostic Index. Alice's psychological support needs will identified and the appropriate interventions will be discussed with a particular focus on Alice's history of depression. The supportive and educational role of the breast care nurse and the multidisciplinary team will be highlighted throughout the study.

Anniversaries

The hundredth anniversary of the outbreak of the First World War is only the first of a large number of major European historical anniversaries that will occur in the coming four years. Other twentieth-century anniversaries include that of the Russian Revolution and the Easter Uprising; notable corollaries from earlier centuries include the Battle of Bannockburn, the Hanoverian succession, the Battle of Waterloo and, perhaps most significant of all, the five hundredth anniversary of the Lutheran Reformation. Rather than commission special issues or other features to tie in to individual anniversaries centred on or relevant to German history in a manner which repeats unthinkingly the conventions of scholarly and popular culture, the editors elected to reflect more fundamentally on what might be at stake in major anniversaries for professional scholars of history. In anticipation of the major wave of scholarly and popular publications, commemorative activities and memory conflicts that each of these will generate, and in order to reflect upon the dynamics of German history, memory and commemoration in a more overtly comparative context, the editors invited a number of scholars working on different national histories to reflect on the possibilities and potential pitfalls such anniversaries offer to historians who tie their work in to such moments. They are Jörg Arnold (Nottingham), Thomas A. Brady (Berkeley), Fearghal McGarry (Queen’s University, Belfast), Tim Grady (Chester) and Dan Healey (St Antony’s College, Oxford). The questions were posed by the editors.

Political Posturing or Real Powers: Control of Genetically Modified Crops by the Member States and their Regions

The cultivation of genetically modified (GM) crops in the EU is highly harmonised, involving a central authorisation procedure that aims to ensure a high level of environmental and human health protection. However conflicts over authority persist and the Commission has responded to a combination of internal and external pressures with a more flexible approach to coexistence, a proposed opt-out clause and recently a promise by the head of the Commission to review the existing EU GM legislative regime, providing an opportunity to consider and suggest paths of development. In light of the significance of multilevel governance and subsidiarity for GM cultivation, this paper considers the policy-making powers of the Member States and subnational regions in this regime, focussing upon post-authorisation options in particular. A number of core mechanisms exist, including voluntary measures, safeguard clauses, coexistence measures, a proposed express opt-out and Article 4(2) TEU on ‘national identity. These mechanisms are examined in light of the goals and challenges of multilevel governance, in order to consider whether the relevant powers are located at the appropriate level. Overall, it is apparent that the developments occurring at the EU level are strengthening multilevel governance, but with significant opportunities to improve it further through focussing on the supporting roles and the regional levels in particular.
