Abstract
The adducts produced by the reaction of cis-diamminedichloroplatinum(II) with DNA have previously been isolated and characterised. These adducts may be measured at the cellular level by immunochemical detection but the accuracy of this assay is dependent on the number of adducts per nucleotide. We have developed a novel assay for cisplatin-DNA adducts, utilising an established method in which platinated DNA is digested to form a mixture of nucleotides and adducts; these are then separated by anion exchange HPLC. The number of cisplatin-DNA adducts is determined by measurement of the platinum content of the HPLC fractions by inductively coupled plasma mass spectrometry. The assay has been validated by cochromatography of purified drug-DNA adducts whose identity has been confirmed by NMR. We describe an application of the assay, namely the measurement of in vitro removal of cisplatin-DNA adducts from calf thymus DNA by cell free extracts derived from tumour cell lines. Adduct removal is dependent on both the amount of extract protein and the duration of the reaction. Almost 70% of adducts are removed from 5mug of DNA (drug:nucleotide ratio 0.08) by 80mug of extract. Other potential applications of the assay are discussed.

Abstract
Background: Ovarian cancer is the most lethal gynaecological cancer. Progression-free and overall survival is significantly related to surgical success and residual disease volume. It is unclear whether this survival advantage is due to an intrinsic biological element of the tumour cells which enables successful surgery and improved prognosis, or alternatively the number of tumour sustaining cells remaining irrespective of differences in biology. Methods: A systematic review of the literature was performed identifying studies that have investigated the association between biomarkers and surgical outcomes. We attempted validation of these results using The Cancer Genome Atlas ovarian cancer data sets. Results: Thirty studies were identified of which sixteen determined protein expression, eight gene expression and one DNA methylation in association with surgical debulking. Individualised linear models adjusting for batch, stage and age identified only expression of the genes MTDH and insulin-like growth factor-1 receptor (IGF1R) to be significantly associated with debulking surgery (P<0.05, false discovery rate (FDR)<5%), although in the case of IGF1R this was in the opposite direction to previous findings. Conclusion: The majority of studies are limited by design, include heterogeneous samples and lack adjustment for major confounding factors. High quality detailed clinical annotations should be routinely collected in future to more accurately evaluate biomarkers of surgical outcome.

Abstract
Field reversed configurations (FRCs) with high confinement are obtained in the C-2 device by combining plasma gun edge biasing and neutral beam injection. The plasma gun creates an inward radial electric field that counters the usual FRC spin-up. The n = 2 rotational instability is stabilized without applying quadrupole magnetic fields. The FRCs are nearly axisymmetric, which enables fast ion confinement. The plasma gun also produces E × B shear in the FRC edge layer, which may explain the observed improved particle transport. The FRC confinement times are improved by factors 2 to 4, and the plasma lifetimes are extended from 1 to up to 4 ms.

Abstract
BACKGROUND While there is a growing body of literature in the quality of life of families that include children with disabilities, the majority of research has been conducted in western countries. The present study provides an initial exploration of the quality of life of Malaysian families that include children with developmental/intellectual disabilities. Dynamics characterising Malaysian society are described as developments in social policy and service delivery that support persons with disabilities and their families. METHOD Questionnaire data were collected using the Family Quality of Life Survey - Short Version. Members of 52 families that included one or two children with disabilities were interviewed. Their responses provided their perceptions within six dimensions of family quality of life across the nine life domains assessed. RESULTS Findings showed a consistent pattern of relatively strong perceived 'importance' ratings in each of life domains as compared to mean ratings for other family quality of life dimensions. Some dimensions of family quality of life, in particular 'opportunities', 'initiative' and 'attainment', demonstrated particularly strong associations with each other. Overall means of satisfaction with and attainment of family quality of life as well as global evaluations of quality of life and satisfaction all demonstrated significant associations, although each of these correlations accounted for less than 50% of the common variance. CONCLUSIONS The importance rating can be viewed as a determining factor in terms of quality of life, and it played a critical role in supporting attainment of, and satisfaction with, family quality of life, assuming opportunities, initiative and stability are adequate. The need for a broader sample including families that were not receiving services was noted. Future research questions based on the results of the current study and some of the dynamics impacting Malaysian society are also suggested.

Abstract
Current discourses in urban water management emphasise a diversity of water sources and scales of infrastructure for resilience and adaptability. During the last 2 decades, in particular, various small-scale systems emerged and developed so that the debate has largely moved from centralised versus decentralised water systems toward governing integrated and networked systems of provision and consumption where small-scale technologies are embedded in large-scale centralised infrastructures. However, while centralised systems have established boundaries of ownership and management, decentralised water systems (such as stormwater harvesting technologies for the street, allotment/house scales) do not, therefore the viability for adoption and/or continued use of decentralised water systems is challenged. This paper brings together insights from the literature on public sector governance, co-production and social practices model to develop an analytical framework for co-governing such systems. The framework provides urban water practitioners with guidance when designing co-governance arrangements for decentralised water systems so that these systems continue to exist, and become widely adopted, within the established urban water regime.

Abstract
Species of the genus Streptomyces, which constitute the vast majority of taxa within the family Streptomycetaceae, are a predominant component of the microbial population in soils throughout the world and have been the subject of extensive isolation and screening efforts over the years because they are a major source of commercially and medically important secondary metabolites. Taxonomic characterization of Streptomyces strains has been a challenge due to the large number of described species, greater than any other microbial genus, resulting from academic and industrial activities. The methods used for characterization have evolved through several phases over the years from those based largely on morphological observations, to subsequent classifications based on numerical taxonomic analyses of standardized sets of phenotypic characters and, most recently, to the use of molecular phylogenetic analyses of gene sequences. The present phylogenetic study examines almost all described species (615 taxa) within the family Streptomycetaceae based on 16S rRNA gene sequences and illustrates the species diversity within this family, which is observed to contain 130 statistically supported clades, as well as many unsupported and single member clusters. Many of the observed clades are consistent with earlier morphological and numerical taxonomic studies, but it is apparent that insufficient variation is present in the 16S rRNA gene sequence within the species of this family to permit bootstrap-supported resolution of relationships between many of the individual clusters.

Abstract
AIM Maturity-onset diabetes of the young is a monogenic form of familial, young-onset diabetes. It is rare (∼1% diabetes) and may be misdiagnosed as Type 1 diabetes and inappropriately treated with insulin. Type 1 diabetes is characterized by the presence of islet autoantibodies, including glutamate decarboxylase (GAD) and islet antigen-2 (IA-2) antibodies. The prevalence of islet autoantibodies is unknown in maturity-onset diabetes of the young and may have the potential to differentiate this form of diabetes from Type 1 diabetes. The aim of this study was to determine the prevalence of GAD and IA-2 antibodies in patients with maturity-onset diabetes of the young and Type 1 diabetes. METHODS We measured plasma GAD and IA-2 antibodies in 508 patients with the most common forms of maturity-onset diabetes of the young (GCK: n = 227; HNF1A: n = 229; HNF4A: n = 52) and 98 patients with newly diagnosed Type 1 diabetes (diagnosed < 6 months). Autoantibodies were considered positive if ≥ 99th centile of 500 adult control subjects. RESULTS GAD and/or IA-2 antibodies were present in 80/98 (82%) patients with Type 1 diabetes and 5/508 (< 1%) patients with maturity-onset diabetes of the young. In the cohort with Type 1 diabetes, both GAD and IA-2 antibodies were detected in 37.8% of patients, GAD only in 24.5% and IA-2 only in 19.4%. All five patients with maturity-onset diabetes of the young with detectable antibodies had GAD antibodies and none had detectable IA-2 antibodies. CONCLUSION The prevalence of GAD and IA-2 antibodies in maturity-onset diabetes of the young is the same as in control subjects (< 1%). The finding of islet autoantibodies, especially IA-2 antibodies, makes the diagnosis of maturity-onset diabetes of the young very unlikely and genetic testing should only be performed if other clinical characteristics strongly suggest this form of diabetes rather than Type 1 diabetes. This supports routine islet autoantibody testing before proceeding to more expensive molecular genetic testing.

Abstract
BACKGROUND Genetic changes have been widely reported in association with cholangiocarcinoma (CCA), while epigenetic changes are poorly characterised. We aimed to further evaluate CpG-island hypermethylation in CCA at candidate loci, which may have potential as diagnostic or prognostic biomarkers. METHODS We analysed methylation of 26 CpG-islands in 102 liver fluke related-CCA and 29 adjacent normal samples using methylation-specific PCR (MSP). Methylation of interest loci was confirmed using pyrosequencing and/or combined bisulfite restriction analysis, and protein expression by immunohistochemistry. RESULTS A number of CpG-islands (OPCML, SFRP1, HIC1, PTEN and DcR1) showed frequency of hypermethylation in >28% of CCA, but not adjacent normal tissues. The results showed that 91% of CCA were methylated in at least one CpG-island. The OPCML was the most frequently methylated locus (72.5%) and was more frequently methylated in less differentiated CCA. Patients with methylated DcR1 had significantly longer overall survival (Median; 41.7 vs 21.7 weeks, P=0.027). Low-protein expression was found in >70% of CCA with methylation of OPCML or DcR1. CONCLUSION Aberrant hypermethylation of certain loci is a common event in liver fluke-related CCA and may potentially contribute to cholangiocarcinogenesis. The OPCML and DcR1 might serve as methylation biomarkers in CCA that can be readily examined by MSP.

Abstract
In recent years, the application of heterogeneous photocatalytic water purification processes has gained wide attention due to its effectiveness in degrading and mineralizing the recalcitrant organic compounds as well as the possibility of utilizing the solar UV and visible-light spectrum. This paper aims to review and summarize the recent works on the titanium dioxide (TiO(2)) photocatalytic oxidation of pesticides and phenolic compounds, predominant in storm and wastewater effluents. The effects of various operating parameters on the photocatalytic degradation of pesticides and phenols are discussed. Results reported here suggest that the photocatalytic degradation of organic compounds depends on the type and composition of the photocatalyst and, light intensity, initial substrate concentration, amount of catalyst, pH of the reaction medium, ionic components in water, solvent types, oxidizing agents/electron acceptors, catalyst application mode, and calcination temperature in the water environment. A substantial amount of research has focused on the enhancement of TiO(2) photocatalysis by modification with metal, non-metal and ion doping. Recent developments in TiO(2) photocatalysis for the degradation of various pesticides and phenols are also highlighted in this review. It is evident from the literature survey that photocatalysis has good potential to remove a variety of organic pollutants. However, there is still a need to determine the practical utility of this technique on a commercial scale.

Abstract
ABSTRACTWe report the corrosion protection properties of a novel conductive polymer coating on aluminum alloys. The conductive polymer coating is a double strand molecular complex of polyaniline and a polyelectrolyte. The double strand polyaniline offers advantages in stability and processability over other forms of conductive polymers. The coated aluminum alloys (AA7075- T6) were evaluated for corrosion protection in an aggressive salt environment of.5N NaCl solutions using cyclic polarization and electrochemical impedance spectroscopy. Corrosion current densities were calculated for uncoated alloy samples and alloys coated with the conductive and non-conductive derivative of the double strand polymer. The conductive form of the double strand polyaniline coating shows a two order of magnitude lowering of the corrosion current over the uncoated samples and a one order magnitude lowering over the non-conductive form of the polymer coated samples. The shape of the cyclic polarization data closely resembles results of sulfuric acid anodized aluminum. This data indicates that the conductive state of the polymer is required for improved corrosion protection and an anodized type protection is occurring.

Abstract
In response to a range of contemporary urban water challenges, there is an increasingly urgent need to change the way water is used in our cities. In Australia, the 'Security through Diversity' policy has been introduced in a number of cities to help facilitate a shift towards sustainable urban water management. This qualitative case study research investigated the interpretation and implementation of this radically different urban water policy approach across the case study cities of Perth and Melbourne. To focus the research and allow for more reliable comparative analysis across the cities, the introduction of desalination and permanent water saving rules as new initiatives in these cities were of particular interest. The research results are drawn from a synthesis of over 65 semi-structured interviews with senior urban water practitioners in the case study cities, and a content analysis of key policy and guidance documents, as well as organizational literature where available. The key finding of this research was that because of an entrenched technological paradigm, and the difficulty in breaking this pattern of lock-in, practitioners are currently interpreting and implementing Security through Diversity in a way that does not fully realise the potential of this strategy. More specifically the interview results revealed that the urban water practitioner community believed that the introduction of seawater desalination would discharge their city's responsibility for achieving Security through Diversity and that demand management initiatives, while nice, are not essential to this policy position. Interestingly, despite context evidence to the contrary, the practitioners believed supply and demand planning to be an integrated practice within their city. The paper concludes by offering some recommendations to facilitate a more comprehensive implementation of Security through Diversity and outlines areas for possible future research.

Abstract
The unprecedented water scarcity in Australia coincides with the adoption of a new urban water rhetoric. The 'Security through Diversity' strategy has been adopted in a number of Australian cities as a new and innovative approach to urban water management. Although this strategy offers a more holistic approach to urban water management, in practice, the Security through Diversity strategy is largely being interpreted and implemented in a way that maintains the historical dependence on large scale, centralised water infrastructure and therefore perpetuates existing urban water vulnerabilities. This research explores the implementation of Security through Diversity as the new water scarcity response strategy in the cities of Perth and Melbourne. Through a qualitative study with over sixty-five urban water practitioners, the results reveal that the practitioners have absorbed the new Security through Diversity language whilst maintaining the existing problem and solution framework for urban water management. This can be explained in terms of an entrenched technological path dependency and cognitive lock-in that is preventing practitioners from more comprehensively engaging with the complexities of the Security through Diversity strategy, which is ultimately perpetuating the existing vulnerability of our cities. This paper suggests that greater engagement with the underlying purpose of the security though diversity strategy is a necessary first step to overcome the constraints of the traditional technological paradigm and more effectively reduce the continued vulnerability of Australian cities.

Abstract
BACKGROUND Previous studies have reported a conflicting relationship between the effect of live and televised sporting events on attendance rates to emergency departments (ED). The objectives of this study were to investigate the relationship of major sporting events on emergency department attendance rates and to determine the potential effects of such events on service provision. METHODS A retrospective analysis of ED attendances to a district general hospital (DGH) and subsequent admissions over a 24-h period following live and televised sporting activities was performed over a 5-year period. Data were compiled from the hospital's emergency record books including the number of attendances, patient demographics, clinical complaint and outcome. Review patients were excluded. Analysis of sporting events was compiled for live local, regional and national events as well as world-wide televised sporting broadcasts. RESULTS A total of 137,668 (80,445 men) patients attended from April 2002 to July 2007. Mean attendance rate per day was 80 patients (men = 47). Mean admission rate was 13.6 patients per day. Major sporting events during the study period included; Soccer: 4 FA Cup and 1 World Cup (WC) finals; Rugby: 47 Six Nations, 25 Six nations games involving Ireland, 1 WC final, 2 WC semi-finals, 2 WC quarter-finals and 4 WC games involving Ireland; and Gaelic Football [Gaelic Athletic Association (GAA)]: 5 All-Ireland finals, 11 semi-finals, 11 quarter-finals and 5 provincial finals. There was a significantly higher patient admission rate during the soccer FA Cup final, Rugby Six Nations and games involving Ireland and for GAA semi- and quarter-final games (p = 0.001-0.01). There was no difference identified in total attendance or non-admission rates for sporting events throughout the study period. Although there was no correlation identified between any of these sporting events and total emergency department attendances (r < 0.15, p > 0.07), multinomial logistic regression demonstrated that FA Cup final (p = 0.001), Rugby Six Nations (p = 0.019), Rugby WC games involving Ireland (p = 0.003), GAA All-Ireland semi- and quarter-finals (p = 0.016; p = 0.016) were predictors of patient admission rates. CONCLUSION This study suggests that live or televised sporting events do not significantly affect ED attendances to a DGH. However, some events appeared to be predictors of patient admission rates. Although it may be beneficial to consider the effect of sporting events on service stratification during these periods, the overall effect is probably minimal and should not create a major concern for future service provision despite the implementation of the European Working Time Directive.

Abstract
A hot stable field-reversed configuration (FRC) has been produced in the C-2 experiment by colliding and merging two high-β plasmoids preformed by the dynamic version of field-reversed θ-pinch technology. The merging process exhibits the highest poloidal flux amplification obtained in a magnetic confinement system (over tenfold increase). Most of the kinetic energy is converted into thermal energy with total temperature (T{i}+T{e}) exceeding 0.5 keV. The final FRC state exhibits a record FRC lifetime with flux confinement approaching classical values. These findings should have significant implications for fusion research and the physics of magnetic reconnection.

Abstract
Routine dental care provided in special care dentistry is complicated by patient specific factors which increase the time taken and costs of treatment. The BDA have developed and conducted a field trial of a case mix tool to measure this complexity. For each episode of care the case mix tool assesses the following on a four point scale: 'ability to communicate', 'ability to cooperate', 'medical status', 'oral risk factors', 'access to oral care' and 'legal and ethical barriers to care'. The tool is reported to be easy to use and captures sufficient detail to discriminate between types of service and special care dentistry provided. It offers potential as a simple to use and clinically relevant source of performance management and commissioning data. This paper describes the model, demonstrates how it is currently being used, and considers future developments in its use.

Peri-operative blood glucose management in general surgery - a potential element for improved diabetic patient outcomes - an observational cohort study. Int J Surg 2010; 8:494-8.

Abstract
BACKGROUND Hyperglycaemia impairs many of the physiological processes involved in recovery from surgery but there is limited research on the effect of optimal peri-operative glucose control in diabetic general surgery patients. The objectives of this study were to assess blood glucose management in diabetic general surgical patients and to determine if protocol deviations were associated with adverse outcomes. METHODS All diabetic patients undergoing elective and emergency general surgical procedures between August 2007 and July 2008 were included in the study. The hospital protocol for peri-operative blood glucose control was based on the Alberti Regimen. Data was collected regarding blood glucose measurements, adherence to protocol and complications following surgery. RESULTS A total of 69 adult patients (M = 44, F = 25; median age 61, range 15-93 years; T1DM = 35, T2DM = 34) were included. 38 patients underwent elective surgery (cholecystectomy, hernia repair, varicose vein surgery) and 31 underwent emergency surgical procedures (laparotomy, incision and drainage of abscess). 10.3% of capillary blood glucose readings were less than 6.1 mmol/l, 32.8% were between 6.1 and 10.0 mmol/l, 44.6% were greater than 10.0 mmol/l 12.3% of scheduled blood glucose measurements were not completed. An insulin-dextrose infusion was indicated in 30 patients, of which 14 (46.7%) were treated according to protocol. In the 16 protocol-deviation cases, insulin was generally either administered according to a sliding scale (6 patients) or not at all during their time on the ward. While an insulin-dextrose infusion was not indicated in 39 patients, 14 (35.9%) of these patients were inappropriately given insulin either as an infusion (8 patients) or according to a sliding scale (6 patients). Overall, only 39 (56.5%) patients were treated according to protocol. The overall complication rate was 29%, which included 7 out of 39 (17.9%) and 13 out of 30 (43.3%) protocol-based and protocol-deviation patients respectively (p = 0.45). CONCLUSION Although not statistically significant, optimal glucose homeostasis according to hospital protocol was associated with a 25.4% reduction in peri-operative complications. We recommend careful blood glucose management according to pre-defined guidelines in all diabetic patients undergoing general surgical procedures.

Abstract
Recidivism is common in patients infected with gonorrhoea. Identifying the factors most closely associated with recurrent gonococcal infection can help to target health promotion and disease prevention interventions. A case-control study design was used to quantify the importance of past infection as a risk marker for gonorrhoea while controlling for other demographic and behavioural factors. Data were available for 134 cases of gonorrhoea and 150 controls. A history of gonorrhoea (odds ratio [OR] 4.36 [95% CI 1.78-10.71]) was the strongest predictor of current infection. The number of partners in the last month (OR 2.19 [95% CI 1.20-4.02]) was also significantly associated with a diagnosis of gonorrhoea. Patients presenting with gonorrhoea are a specific high-risk group who require additional interventions and should be prioritized for evidence-based, enhanced and interactive counselling.
