Medical Investigation and Documentation of Torture: A Handbook for Health Professionals
This Handbook is primarily aimed at raising awareness of relevant medical ethical, legal and professional standards of the many health professionals who would wish to do the most conscientious job, with a view to helping victims of torture and contributing to efforts to eliminate the practice. The key task is to establish the most scientifically valid documentation concerning possible torture of individuals, consistent with the often difficult conditions under which the work sometimes has to be undertaken. It is inspired by The Istanbul Protocol, approved by United Nations bodies, which lays down the best professional standards for physicians working in the field. Yet it recognises that not all health professionals called on to do the work will have extensive experience in this field and it presents the material in a way that aims to be accessible to all these professionals. Guidance is given in the general skills of interviewing, as well as the medical examination and documentation. In addition to the relevant ethical and legal principles, the Handbook also points to sources of advice for those who wish to further their knowledge or gain support and advice on particular situations
Characterisation of a novel reverse-biased PPD CMOS image sensor
A new pinned photodiode (PPD) CMOS image sensor (CIS) has been developed and characterised. The sensor can be fully depleted by means of reverse bias applied to the substrate, and the principle of operation is applicable to very thick sensitive volumes. Additional n-type implants under the pixel p-wells, called Deep Depletion Extension (DDE), have been added in order to eliminate the large parasitic substrate current that would otherwise be present in a normal device. The first prototype has been manufactured on a 18 μm thick, 1000 Ω .cm epitaxial silicon wafers using 180 nm PPD image sensor process at TowerJazz Semiconductor. The chip contains arrays of 10 μm and 5.4 μm pixels, with variations of the shape, size and the depth of the DDE implant. Back-side illuminated (BSI) devices were manufactured in collaboration with Teledyne e2v, and characterised together with the front-side illuminated (FSI) variants. The presented results show that the devices could be reverse-biased without parasitic leakage currents, in good agreement with simulations. The new 10 μm pixels in both BSI and FSI variants exhibit nearly identical photo response to the reference non-modified pixels, as characterised with the photon transfer curve. Different techniques were used to measure the depletion depth in FSI and BSI chips, and the results are consistent with the expected full depletion
Large-scale and significant expression from pseudogenes in Sodalis glossinidius – a facultative bacterial endosymbiont
The majority of bacterial genomes have high coding efficiencies, but there are some genomes of intracellular bacteria that have low gene density. The genome of the endosymbiont Sodalis glossinidius contains almost 50 % pseudogenes containing mutations that putatively silence them at the genomic level. We have applied multiple ‘omic’ strategies, combining Illumina and Pacific Biosciences Single-Molecule Real-Time DNA sequencing and annotation, stranded RNA sequencing and proteome analysis to better understand the transcriptional and translational landscape of Sodalis pseudogenes, and potential mechanisms for their control. Between 53 and 74 % of the Sodalis transcriptome remains active in cell-free culture. The mean sense transcription from coding domain sequences (CDSs) is four times greater than that from pseudogenes. Comparative genomic analysis of six Illumina-sequenced Sodalis isolates from different host Glossina species shows pseudogenes make up ~40 % of the 2729 genes in the core genome, suggesting that they are stable and/or that Sodalis is a recent introduction across the genus Glossina as a facultative symbiont. These data shed further light on the importance of transcriptional and translational control in deciphering host–microbe interactions. The combination of genomics, transcriptomics and proteomics gives a multidimensional perspective for studying prokaryotic genomes with a view to elucidating evolutionary adaptation to novel environmental niches
A proteomics study of the response of North Ronaldsay sheep to copper challenge
BACKGROUND: The objective of this proteomics study was to identify proteins that changed expression as a result of copper challenge in the uniquely copper sensitive North Ronaldsay sheep and further, to compare those changes in expression with the more copper tolerant Cambridge breed. Such data gives us a proteome-centered perspective of the pathogenesis of copper-induced oxidative stress in this breed. RESULTS: Many proteins respond to copper challenge, but this study focuses on those exhibiting a differential response between the two breeds, related to liver copper content. As copper accumulated in the tissue, the pattern of expression of several proteins was markedly different, in North Ronaldsay sheep as compared to the Cambridge breed. CONCLUSION: The pattern of changes was consistent with the greatly enhanced susceptibility of North Ronaldsay sheep to copper-induced oxidative stress, focused on mitochondrial disturbance with consequent activation of hepatic stellate cells. The expression profiles were sufficiently complex that the response could not simply be explained as a hypersensitivity to copper in North Ronaldsay sheep
Suited for Success? : Suits, Status, and Hybrid Masculinity
This document is the Accepted Manuscript version. The final, definitive version of this paper has been published in Men and Masculinities, March 2017, doi: https://doi.org/10.1177/1097184X17696193, published by SAGE Publishing, All rights reserved.This article analyzes the sartorial biographies of four Canadian men to explore how the suit is understood and embodied in everyday life. Each of these men varied in their subject positions—body shape, ethnicity, age, and gender identity—which allowed us to look at the influence of men’s intersectional identities on their relationship with their suits. The men in our research all understood the suit according to its most common representation in popular culture: a symbol of hegemonic masculinity. While they wore the suit to embody hegemonic masculine configurations of practice—power, status, and rationality—most of these men were simultaneously marginalized by the gender hierarchy. We explain this disjuncture by using the concept of hybrid masculinity and illustrate that changes in the style of hegemonic masculinity leave its substance intact. Our findings expand thinking about hybrid masculinity by revealing the ways subordinated masculinities appropriate and reinforce hegemonic masculinity.Peer reviewe
Lymph Node Harvest in Dukes' A Cancer Pathologist May Need to Consider Fat Dissolving Technique: An Observational Study
Background. National institute of clinical excellence (NICE) recommends that a median of 12 lymph nodes be examined in patients operated on with curative intent- to- treat colorectal cancer (CRC). Patients with lymph node harvest less than this may be considered under staged and may receive adjuvant chemotherapy. The aim of our study was to ascertain median number of lymph nodes examined in early colorectal cancers. Method. Patients undergoing colorectal resection between June 2007 and May 2008 were identified and pathological staging obtained using pathology database. Results. 146 patients underwent standardised laparoscopic or open resection of colorectal cancers during this period. Overall median number of lymph nodes harvested/patient was 14 (3–40). When analysed by stage, median number of lymph nodes harvested in Dukes' A, B, and C cancers was 10, 14, and 15, respectively. 11/18 (61%) patients with Dukes' A carcinoma had lymph node harvest of less than 12 compared with 15/55 (27%) patients with Dukes' B. Conclusion. Lymph node harvest in Dukes' A cancers using standard techniques tends to be low. Pathologists may have to consider special techniques in harvesting lymph nodes for early colorectal cancers
Protein processing characterized by a gel-free proteomics approach
We describe a method for the specific isolation of representative N-terminal peptides of proteins and their proteolytic fragments. Their isolation is based on a gel-free, peptidecentric proteomics approach using the principle of diagonal chromatography. We will indicate that the introduction of an altered chemical property to internal peptides holding a free α-N-terminus results in altered column retention of these peptides, thereby enabling the isolation and further characterization by mass spectrometry of N-terminal peptides. Besides pointing to changes in protein expression levels when performing such proteome surveys in a differential modus, protease specificity and substrate repertoires can be allocated since both are specified by neo-N-termini generated after a protease cleavage event. As such, our gel-free proteomics technology is widely applicable and amenable for a variety of proteome-driven protease degradomics research
'Lad culture' in higher education: agency in the sexualisation debates
This paper reports on research funded by the National Union of Students, which explored women students’ experiences of ‘lad culture’ through focus groups and interviews. We found that although laddism is only one of various potential masculinities, for our participants it dominated social and sexual spheres of university life in problematic ways. However, their objections to laddish behaviours did not support contemporary models of ‘sexual panic’, even while oppugning the more simplistic celebrations of young women’s empowerment which have been observed in debates about sexualisation. We argue that in their ability to reject ‘lad culture’, our respondents expressed a form of agency which is often invisibilised in sexualisation discussions and which could be harnessed to tackle some of the issues we uncovered
Lateral enamel growth in human incisors from Çatalhöyük in Turkey
Whereas the differences in lateral enamel growth between fossil and modern populations have been well documented in recent years, few studies report on the variability in perikymata counts and distribution between modern human populations. There is a need for information on modern human populations from a wide range of geographical regions and archaeological populations to determine whether existing patterns are representative. The aim of this paper is to document enamel surface microstructures in human teeth from a previously unknown region and time period comprehensively

Cost-effectiveness of telehealth in people with social care needs: the Whole Systems Demonstrator cluster randomised trial
Introduction: The Whole Systems Demonstrator pilots introduced telehealth and telecare into three local authority areas using an integrated approach to deliver health and social care to those with high care needs and long-term conditions. Proponents of these technologies have given cost savings as one rationale for advocating their introduction and widespread implementation; proponents have also advocated their potential to improve the quality of life for their users. Until recently, evaluations of telehealth and telecare in high-income countries have been based on relatively small-scale pilots; few such evaluations have been designed as randomised controlled trials. The WSD study was a pragmatic cluster-randomised control trial, representing the largest-scale trial of telehealth and telecare to be carried out in the UK. This presentation focuses on the results of the WSD telecare questionnaire study.
Objectives: To examine the costs and cost-effectiveness of telecare compared to standard support and treatment.
Methods: Economic evaluation conducted in parallel with a pragmatic cluster-randomised controlled trial of Telecare. 2600 people with social care needs participated in a trial of a community-based telecare intervention in three English local authority areas. Approximately half of the participants in the telecare trial also consented to participate in the WSD telecare questionnaire study, which collected information on a number of patient-reported outcome measures and also on the self-reported use of a range of health and social services. Health and social costs were calculated by attaching nationally applicable unit costs to self-reported service use data. The unit costs of telecare support and treatment provided were calculated drawing on administrative and financial data sources and interviews with key informants. The primary outcome for the cost-effectiveness analysis was the quality-adjusted life year (QALY). Secondary outcomes included measures of health-related quality of life and well-being. We employed multivariate analyses to explore the cost-effectiveness of the intervention
Results: The presentation will describe the results of the economic evaluation of telecare, addressing the cost of care and treatment packages used by those participating in the telecare questionnaire study and the results of the cost-effectiveness analysis. These results will be available by the time of the presentation.
Conclusions: These will be available by the time of the presentation
