Trust, Nostalgia and Narrative Accounts of Blood Banking in England in the 21st Century

Historically, cultural accounts and descriptions of blood banking in Britain have been associated with notions of altruism, national solidarity and imagined community. While these ideals have continued to be influential, the business of procuring and supplying blood has become increasingly complex. Drawing on interview data with donors in one blood centre in England, this article reports that these donors tend not to acknowledge the complex dynamics of production and exchange in modern blood systems. This, it is argued, is congruent with nostalgic narratives in both popular and official accounts of blood services, which tend to bracket these important changes. A shift to a more open institutional narrative about modern blood services is advocated, as blood services face current and future challenges

A new look at the purported health benefits of commercial and natural clays

Clays attributed to have medicinal properties have been used since prehistoric times and are still used today as complementary medicines, which has given rise to unregulated “bioceutical” clays to treat skin conditions. Recently, clays with antibacterial characteristics have been proposed as alternatives to antibiotics, potentially overcoming modern day antibiotic resistance. Clays with suggested antibacterial properties were examined to establish their effects on common wound-infecting bacteria. Geochemical, microscopical, and toxicological characterization of clay particulates, their suspensions and filtered leachates was performed on THP-1 and HaCaT cell lines. Cytoskeletal toxicity, cell proliferation/viability (MTT assays), and migration (scratch wounds) were further evaluated. Clays were assayed for antibacterial efficacy using minimum inhibitory concentration assays. All clays possessed a mineral content with antibacterial potential; however, clay leachates contained insufficient ions to have any antibacterial effects. All clay leachates displayed toxicity towards THP-1 monocytes, while clay suspensions showed less toxicity, suggesting immunogenicity. Reduced clay cytotoxicity on HaCaTs was shown, as many leachates stimulated wound-healing responses. The “Green” clay exhibited antibacterial effects and only in suspension, which was lost upon neutralization. pH and its interaction with clay particle surface charge is more significant than previously understood to emphasize dangers of unregulated marketing and unsubstantiated bioceutical claims

One step forward, one step sideways? Expanding research capacity for neglected diseases

<p>Abstract</p> <p>Background</p> <p>There is general agreement, including from the pharmaceutical industry, that current market based methods of generating research into the development of pharmaceutical products that are relevant for developing countries do not work. This conclusion is relevant not just for the most neglected diseases such as leishmaniasis but even for global diseases such as cancer and cardiovascular disease.</p> <p>Discussion</p> <p>Stimulating research will mean overcoming barriers such as patent thickets, poor coordination of research activities, exclusive licensing of new technologies by universities and the structural problems that inhibit conducting appropriate clinical trials in developing countries. In addition, it is necessary to ensure that the priorities for research reflect the needs of developing countries and not just donors. This article will explore each of these issues and then look at three emerging approaches to stimulating research -paying for innovation, priority review sales or vouchers and public-private partnerships, - and evaluate their strengths and weaknesses.</p> <p>Summary</p> <p>All of the stakeholders agree that there is a pressing need for a major expansion in the level of R&D. Whatever that new model turns out to be, it will have to deal with the 5 barriers outlined in this paper. Finally, none of the three proposals considered here for expanding research is free from major limitations.</p

The Cost of Antibiotic Mass Drug Administration for Trachoma Control in a Remote Area of South Sudan

Trachoma is one of a group of so-called “neglected tropical diseases” (NTDs) for which safe and effective treatments are available. The International Trachoma Initiative oversees donation of the antibiotic azithromycin to endemic countries. Delivery of this drug to communities affected by trachoma is the responsibility of national programmes and their implementing partners, and should be conducted as part of a comprehensive control strategy termed “SAFE,” which includes trichiasis surgery, health education and water/sanitation interventions. There are little data on how much the different components of a trachoma control programme cost and none from South Sudan. To inform budgeting to scale up control of trachoma, and of other NTDs whose control relies on large-scale mass drug administration (MDA), the present study set out to determine the cost per person treated when antibiotics were delivered through a vertical campaign that covered 94% of the target population in a remote trachoma endemic area of South Sudan. The average economic cost per person treated was USD 1.53, which included all inputs not paid for in cash except for the cost of the donated azithromycin and the opportunity cost of community members attending treatment

Peddling a semiotics of fear: a critical examination of scare tactics and commercial strategies in public health promotion

This study critically examines the ways in which the nationwide Diabetes UK/Tesco public health promotion campaign (2013-2014) sought to raise awareness of Type 2 diabetes. Conducting a multimodal critical discourse analysis of six campaign images, we identify the presence of fear-inducing, stigmatising and commercial strategies, through which the campaign emphasises the dangers of diabetes and advocates personal responsibility for assessing both individual and others’ risk of the disease. Specifically, three discursive techniques are deployed in this campaign to achieve these ends: (1) the depiction of grief and amplification of diabetes-related danger, (2) the promotion of diabetes risk and responsibilization of individuals for their health, and (3) the commercial branding and framing of the Diabetes UK/Tesco partnership as providing tools for diabetes prevention and management. Our findings raise concerns about the moral legitimacy of using fear-inducing and commercial strategies in public health campaigns, strategies which do little to address the environmental factors which are associated with increasing rates of the disease

Albert Pierrepoint and the cultural persona of the twentieth-century hangman

Albert Pierrepoint was Britain’s most famous 20th-century hangman. This article utilises diverse sources in order to chart his public representation, or cultural persona, as hangman from his rise to prominence in the mid-1940s to his portrayal in the biopic Pierrepoint(2005). It argues that Pierrepoint exercised agency in shaping this persona through publishing his autobiography and engagement with the media, although there were also representations that he did not influence. In particular, it explores three iterations of his cultural persona – the Professional Hangman, the Reformed Hangman and the Haunted Hangman. Each of these built on and reworked historical antecedents and also communicated wider understandings and contested meanings in relation to capital punishment. As a hangman who remained in the public eye after the death penalty in Britain was abolished, Pierrepoint was an important, authentic link to the practice of execution and a symbolic figure in debates over reintroduction. In the 21st century, he was portrayed as a victim of the ‘secondary trauma’ of the death penalty, which resonated with worldwide campaigns for abolition

Sterility and Gene Expression in Hybrid Males of Xenopus laevis and X. muelleri

BACKGROUND: Reproductive isolation is a defining characteristic of populations that represent unique biological species, yet we know very little about the gene expression basis for reproductive isolation. The advent of powerful molecular biology tools provides the ability to identify genes involved in reproductive isolation and focuses attention on the molecular mechanisms that separate biological species. Herein we quantify the sterility pattern of hybrid males in African Clawed Frogs (Xenopus) and apply microarray analysis of the expression pattern found in testes to identify genes that are misexpressed in hybrid males relative to their two parental species (Xenopus laevis and X. muelleri). METHODOLOGY/PRINCIPAL FINDINGS: Phenotypic characteristics of spermatogenesis in sterile male hybrids (X. laevis x X. muelleri) were examined using a novel sperm assay that allowed quantification of live, dead, and undifferentiated sperm cells, the number of motile vs. immotile sperm, and sperm morphology. Hybrids exhibited a dramatically lower abundance of mature sperm relative to the parental species. Hybrid spermatozoa were larger in size and accompanied by numerous undifferentiated sperm cells. Microarray analysis of gene expression in testes was combined with a correction for sequence divergence derived from genomic hybridizations to identify candidate genes involved in the sterility phenotype. Analysis of the transcriptome revealed a striking asymmetric pattern of misexpression. There were only about 140 genes misexpressed in hybrids compared to X. laevis but nearly 4,000 genes misexpressed in hybrids compared to X. muelleri. CONCLUSIONS/SIGNIFICANCE: Our results provide an important correlation between phenotypic characteristics of sperm and gene expression in sterile hybrid males. The broad pattern of gene misexpression suggests intriguing mechanisms creating the dominance pattern of the X. laevis genome in hybrids. These findings significantly contribute to growing evidence for allelic dominance in hybrids and have implications for the mechanism of species differentiation at the transcriptome level
