DEFRApH - Sample collection and handling procedures
All chemical and biogeochemical process in the sea are affected by the acidity of the water. Acidity is therefore fundamental property of seawater. The growing concern that the acidity of the oceans might be increasing has revealed weaknesses in our knowledge of this fundamental property and its variation in space and time. In 2008 the DEFRApH project (DEFRA contract ME4133) was initiated to provide this missing information in UK related waters. It required sampling for and analysis of the total inorganic carbon and total alkalinity content of samples. This reports documents the procedures sued for sampling. A companion document Hartman Dumousseaud and Roberts (NOC Internal Document No. 01) describes in detail the analytical procedures used and the calculation of the results

Sunitinib treatment exacerbates intratumoral heterogeneity in metastatic renal cancer

Stewart) and an educational grant from Pfizer (to T. Powles).Purpose: The aim of this study was to investigate the effect of VEGF targeted therapy (sunitinib) on molecular intratumoral heterogeneity (ITH) in metastatic clear cell renal cancer (mccRCC). Experimental design: Multiple tumor samples (n=187 samples) were taken from the primary renal tumors of mccRCC patients who were sunitinib treated (n=23, SuMR clinical trial) or untreated (n=23, SCOTRRCC study). ITH of pathological grade, DNA (aCGH), mRNA (Illumina Beadarray) and candidate proteins (reverse phase protein array) were evaluated using unsupervised and supervised analyses (driver mutations, hypoxia and stromal related genes). ITH was analysed using intratumoral protein variance distributions and distribution of individual patient aCGH and gene expression clustering. Results: Tumor grade heterogeneity was greater in treated compared to untreated tumors (P=0.002). In unsupervised analysis, sunitinib therapy was not associated with increased ITH in DNA or mRNA. However, there was an increase in ITH for the driver mutation gene signature (DNA and mRNA) as well as increasing variability of protein expression with treatment (p<0.05). Despite this variability, significant chromosomal and transcript changes to key targets of sunitinib, such as VHL, PBRM1 and CAIX, occurred in the treated samples. Conclusions: These findings suggest that sunitinib treatment has significant effects on the expression and ITH of key tumor and treatment specific genes/proteins in mccRCC. The results, based on primary tumor analysis, do not support the hypothesis that resistant clones are selected and predominate following targeted therapy.Peer reviewe

Is the biology of breast cancer changing? A study of hormone receptor status 1984-1986 and 1996-1997
Using archived tumours, those from 1984-1986 and 1996-1997 underwent immunohistochemistry for hormone receptors and grade analysis. A significant shift towards more ER-positive and low-grade disease was found; this appears to reflect screening practices, but could still influence survival
Critical Issue 3: Prison Social Climates
In this chapter, we focus on the influence of the prison social climate on institutional violence. The climate of a prison represents the middle level of the ecology, shaped by individual, subcultural, organisational, and community-level factors. We argue that there is a need to both conceptualise and define the climate of a prison, as well as find ways to operationalise key constructs such that valid and reliable data can be collected and used to drive prevention efforts. Both psychological and sociological conceptualisations of the prison social climate are considered, along with suggestions for how to prevent violence by strengthening or improving the social climate. Finally, some recommendations for future research in this area are proposed.Jennifer J. Galouzis, Andrew Day, Catia G. Malvaso, and Rhiannon Pilkingto
Preventing Prison Violence
In this chapter, we explore the implications of adopting a public health approach to prison violence prevention. Building on the WHO's violence prevention approach, we apply a four-stage approach: (1) defining the problem, including the scope and scale of prison violence and the outcomes we want to achieve; (2) understanding why prison violence occurs; (3) designing, implementing, and evaluating efforts to reduce prison violence; and (4) implementing multi-faceted preventative interventions. We also identify numerous challenges to implementing a public health approach, including those associated with the need to routinely collect high-quality data that can be linked to data from adjacent agencies, connect data to theory, develop an evidence base on effective preventative interventions, and address the inherent difficulties of rigorous evaluation in this area. We have, albeit cautiously, suggested that the public health model provides a useful framework from which to develop a comprehensive violence prevention strategy. However, it is also clear that this will require significant engagement with stakeholders—from people in prison to politicians—and sustained investment not only in specialist violence prevention programmes but also to support the longer-term goals of successful rehabilitation, reintegration, and improving social and emotional wellbeing.Catia G.

Wavelength tunable 10-GHz 3-ps pulse source using a dispersion decreasing fiber-based nonlinear optical loop mirror
We experimentally demonstrate the use of a dispersion decreasing fiber (DDF)-based nonlinear optical loop mirror (NOLM) for the generation of wavelength tunable soliton-like pulses at a repetition rate of 10 GHz. We compress ~12 ps Gaussian pulses from an electro-absorption modulator (EAM) (followed by 125 m of DCF for preliminary linear dispersion compensation) into 3 ps pedestal-free pulses using both high-order soliton compression and nonlinear switching effects within an 8.5 km DDF-based loop mirror. The output pulses from the DDF-based NOLM show considerable pedestal reduction compared to those obtained by directly compressing the EAM seed pulses via a single passage through the DDF. Wavelength tuning of the compressed pulses over a ~15 nm bandwidth (from 1541 to 1556 nm) is demonstrated without a significant increase in pulse duration or degradation in pulse quality
An Approach to Preventing Prison Violence
In this chapter, we outline an approach to preventing prison violence that is informed by the other chapters in this book. We adopt a broad public health approach to prevention based on the identification of risk factors and an understanding of why prison violence occurs before discussing the importance of returning “data to source” and partnering with key stakeholders to identify prevention initiatives that are likely to work in the specific setting or context under consideration. The chapter concludes with a discussion about some of the challenges faced by those seeking to implement violence prevention initiatives in prisons.Andrew Day, Catia G. Malvaso, Jennifer J.
