    Evolution of candidate transcriptional regulatory motifs since the human-chimpanzee divergence.

    Get PDF
    BACKGROUND: Despite the recent completion of the chimpanzee genome project, few functionally significant sequence differences between humans and chimpanzees have thus far been identified. Alteration in transcriptional regulatory mechanisms represents an important platform for evolutionary change, suggesting that a significant proportion of functional human-chimpanzee sequence differences may affect regulatory elements. RESULTS: To explore this hypothesis, we performed genome-wide identification of conserved candidate transcription-factor binding sites that have evolved since the divergence of humans and chimpanzees. Analysis of candidate transcription-factor binding sites conserved between mouse and chimpanzee yet absent in human indicated that loss of candidate transcription-factor binding sites in the human lineage was not random but instead correlated with the biologic functions of associated genes. CONCLUSION: Our data support the notion that changes in transcriptional regulation have contributed to the recent evolution of humans. Moreover, genes associated with mutated candidate transcription-factor binding sites highlight potential pathways underlying human-chimpanzee divergence.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

    Asthma and PM10

    Get PDF
    PM(10) (the mass of particles present in the air having a 50% cutoff for particles with an aerodynamic diameter of 10 μm) is the standard measure of particulate air pollution used worldwide. Epidemiological studies suggest that asthma symptoms can be worsened by increases in the levels of PM(10). Epidemiological evidence at present indicates that PM(10) increases do not raise the chances of initial sensitisation and induction of disease, although further research is warranted. PM(10) is a complex mixture of particle types and has many components and there is no general agreement regarding which component(s) could lead to exacerbations of asthma. However pro-inflammatory effects of transition metals, hydrocarbons, ultrafine particles and endotoxin, all present to varying degrees in PM(10), could be important. An understanding of the role of the different components of PM(10) in exacerbating asthma is essential before proper risk assessment can be undertaken leading to advice on risk management for the many asthmatics who are exposed to air pollution particles

    Mapping ‘Wordsworthshire’: A GIS Study of Literary Tourism in Victorian Lakeland

    Get PDF
    This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Victorian Culture on 14/08/2015, available online: doi: 10.1080/13555502.2015.1058089This article answers the call for scholarship that models the implementation of geographic information systems (GIS) technologies in literary-historical research. In doing so, it creates a step change to the integration of digital methodologies in the humanities. Combining methods and perspectives from cultural history, literary studies, and geographic information sciences, the article confirms, challenges, and extends understanding of Victorian literary tourism in the English Lake District. It engages with the accounts of several nineteenth-century tourists, paying specific attention to Nathaniel Hawthorne’s English Notebooks and Hardwicke Drummond Rawnsley’s A Coach Drive at the Lakes, which are examined alongside contemporaneous guidebooks and other commercial tourist publications. In the process, the article draws attention to a spatial correlation between the route of the Ambleside turnpike (the Lake District’s principal coach road) and the major literary sites to which Victorian Lakeland visitors were guided. Recognizing this correlation, we contend, helps to deepen our appreciation of how the physical and imaginative geographies of the Lake District region interrelate. Specifically, it helps us appreciate how the Victorian fascination with the Lakeland’s literary associations was modulated not only by interest in the region’s other attractions, but also by material conditions on the ground

    Invading Interpreters and Politic Picklocks: Reading Jonson Historically

    Get PDF
    A central problem in the methodology of both the new and 'old' historicism turns on the nature of the link that is assumed to exist between historical description and literary interpretation. The monolithic accounts of Elizabethan systems of belief assembled by so-called old historicists such as E.M.W. Tillyard (it is common these days to complain) seem often quite at variance with the diverse and at times rebellious energies of the literary texts which they are apparently devised to illuminate. Even in the work of a more sophisticated old historicist such as L.C. Knights the supposedly related activities of historical and literary investigation seem often to tug in contrary directions. The divergence is apparent, for example, in the very structure of Knights's influential study of Drama and Society in the Age of Jonson, the first half of which offers a stolid, Tawney-derived historical account of economic conditions in England during the late Elizabethan, early Jacobean period (entitled 'The Background'), while the second half ('The Dramatists') advances livelier readings ofthe work of individual authors. The connections here between foreground and 'background', text and context, 'drama' and 'society', literature and history are quite loosely articulated and theoretically undeveloped. A similar disjunction is often evident in the work of a new historicist such as Stephen Greenblatt, as he turns from a closely-worked meditation upon a particular and highly intriguing historical incident - often quirky in nature, but assumed also to be in some way exemplary - to ponder the particularities of a literary text. The transition is generally athletic and exhilarating in its unexpectedness: a leap from the historical platform across a void to the literary cross-bar, upon which further agile feats are soon to be performed. This is a thoroughly postmodem manoeuvre, challenging precisely on account of its discontinuity, undertaken as coolly as flipping across the television channels, defying (though not perhaps wholly obliterating) old-fashioned expectations of argumentative sequentiality

    Chapter 12 Landscape Appreciation in the English Lake District

    Get PDF
    "The relational complexity of urban and rural landscapes in space and in time. The development of historical geographical information systems (HGIS) and other methods from the digital humanities have revolutionised historical research on cultural landscapes. Additionally, the opening up of increasingly diverse collections of source material, often incomplete and difficult to interpret, has led to methodologically innovative experiments. One of today’s major challenges, however, concerns the concepts and tools to be deployed for mapping processes of transformation—that is, interpreting and imagining the relational complexity of urban and rural landscapes, both in space and in time, at micro- and macro-scale. Mapping Landscapes in Transformation gathers experts from different disciplines, active in the fields of historical geography, urban and landscape history, archaeology and heritage conservation. They are specialised in a wide variety of space-time contexts, including regions within Europe, Asia, and the Americas, and periods from antiquity to the 21st century.

    Ben Jonson and the Story of Charis

    Get PDF
    'A Celebration of Charis in Ten Lyric Pieces' (The Underwood, 2) is one of the most attractive and seemingly most accessible of all Ben Jonson's poetic works. Subtle, humorous, and enchanting, these often admired lyrics appear at a casual reading to present few problems of exegesis or interpretation. Yet the sequence has provoked sharply divergent readings over recent years. There is continuing disagreement amongst critics about the tone and seriousness of the sequence, about the contexts (intellectual, historical, and literary) within which it may need to be understood, and even about the main outlines of the narrative which these seemingly simple lyrics seemingly unfold

    Marlowe, Jonson, and the origins of evil

    Get PDF
    I. Where does evil come from ? Many years ago Tertullian complained that heretics spent far too much of their time worrying about this problem, yet Tertullian himself worried about it incessantly, as did most of the early Fathers of the Church . The question returns insistently in the work of Shakespeare and his contemporaries. Today, when explanations of the origins of evil are more likely to be framed in psychological and sociological terms than theologically, it still baffles and disturbs ..
