Abstract
INTRODUCTION Public and political pressures are increasing on doctors and in particular surgeons to demonstrate competence assurance. While surgical audit is an integral part of surgical practice, its implementation and delivery at a national level in Ireland is poorly developed. Limits to successful audit systems relate to lack of funding and administrative support. In Wexford General Hospital, we have a comprehensive audit system which is based on the Lothian Surgical Audit system. MATERIALS AND METHODS We wished to analyse the amount of time required by the Consultant, NCHDs and clerical staff on one surgical team to run a successful audit system. Data were collected over a calendar month. This included time spent coding and typing endoscopy procedures, coding and typing operative procedures, and typing and signing discharge letters. RESULTS The total amount of time spent to run the audit system for one Consultant surgeon for one calendar month was 5,168 min or 86.1 h. Greater than 50% of this time related to work performed by administrative staff. Only the intern and administrative staff spent more than 5% of their working week attending to work related to the audit. CONCLUSIONS An integrated comprehensive audit system requires a very little time input by Consultant surgeons. Greater than 90% of the workload in running the audit was performed by the junior house doctors and administrative staff. The main financial implications for national audit implementation would relate to software and administrative staff recruitment. Implementation of the European Working Time Directive in Ireland may limit the time available for NCHD's to participate in clinical audit.

Abstract
BACKGROUND The frequency of young people cutting themselves appears to be increasing, with one review estimating the current prevalence across the UK to be between 1 in 12 and 1 in 15. AIM To identify factors that are associated with self-harm by cutting, and more especially coping strategies that if encouraged might reduce such behaviour. METHOD Multivariate and exploratory factor analysis were used to analyse the results from a survey of the pupils attending four large comprehensive schools in the North of England where the frequency of cutting behaviour was causing concern. RESULTS Three factors were identified from the analysis - Social & Active Coping, Seeking External Solutions and Non-Productive Coping. The Social & Active Coping was the only factor that significantly correlated with non-cutting behaviour. CONCLUSIONS The fostering of the elements that make up Social & Active Coping - namely working successfully and feeling a sense of achievement, together with positive friendship networks and positive diversions, including physical recreation, will help to minimize young people's sense of needing to cope by cutting themselves.

Abstract
This unit describes the selection of aptamers from a single-stranded RNA pool that bind to small molecule targets. Aptamers generated by this type of selection experiment can potentially function as receptors for small molecules in numerous applications, including medical diagnostics, therapeutics, and environmental monitoring. This unit describes two modes of selection, one by column filtration and one by batch selection.

Abstract
This unit describes the selection of aptamers from a pool of single-stranded RNA by binding to a protein target. Aptamers generated from this selection experiment can potentially act as protein function inhibitors, and may find applications as therapeutic or diagnostic reagents. A pool of dsDNA is used to generate an ssRNA pool, which is mixed with the protein target. Bound complexes are separated from unbound reagents by filtration, and the RNA:protein complexes are amplified by a combination of reverse transcription, PCR, and in vitro transcription.

Abstract
Preparation of a random-sequence DNA pool is presented. The degree of randomization and the length of the random sequence are discussed, as is synthesis of the pool using a DNA synthesizer or via commercial synthesis companies. Purification of a single-stranded pool and conversion to a double-stranded pool are presented as step-by-step protocols. Support protocols describe determination of the complexity and skewing of the pool, and optimization of amplification conditions.

Abstract
Improved diagnostic reagents would be of considerable benefit in enhancing the specificity and sensitivity of rapid assays for Burkholderia pseudomallei, the causative agent of melioidosis. The purpose of this work is to develop aptamers, high affinity RNA-based molecular recognition molecules, which could be used as reagents for identification of the whole organism in assays of biological samples. Data are presented demonstrating the purification of recombinant B. pseudomallei secreted or surface-exposed macromolecules, which have been expressed in Escherichia coli, and the initial stages of aptamer generation using these recombinant proteins. Future studies will focus upon the expansion of this methodology to include other target macromolecules located on or near the outer membrane of this organism.

Abstract
Recent progress in the research of mesenchymal stromal cells/multipotent stromal cells (MSC) has revealed numerous beneficial innate characteristics, suggesting potential value in an array of cellular therapies. MSC are easily isolated from bone marrow (BM), fat and other tissues, and are readily propagated in vitro. Transplanted/injected MSC have been shown to migrate to a variety of organs and tissues; however, sites of inflammation and pathology elicit enhanced MSC homing for tissue remodeling and repair. Tumors utilize many of the same inflammatory mediators uncovered in wound healing and likewise provide a site for preferential MSC homing. Although incorporation into the tumor microenvironment is apparent, the role of recruited MSC in the tumor microenvironment remains unclear. Some published studies have shown enhancement of tumor growth and development, perhaps through immunomodulatory and pro-angiogenic properties, while others have shown no apparent effect or have demonstrated inhibition of tumor growth and extended survival. This controversy remains at the forefront as clinical applications of MSC commence in anti-tumor therapies as well as as adjuncts to stem cell transplantation and in ameliorating graft-versus-host disease. Careful analysis of past studies and thoughtful design of future experiments will help to resolve the discrepancies in the field and lead to clinical utility of MSC in disease treatment. This review highlights the current theories of the role of MSC in tumors and explores current controversies.
