    The RCSB Protein Data Bank: views of structural biology for basic and applied research and education.

    Get PDF
    The RCSB Protein Data Bank (RCSB PDB, http://www.rcsb.org) provides access to 3D structures of biological macromolecules and is one of the leading resources in biology and biomedicine worldwide. Our efforts over the past 2 years focused on enabling a deeper understanding of structural biology and providing new structural views of biology that support both basic and applied research and education. Herein, we describe recently introduced data annotations including integration with external biological resources, such as gene and drug databases, new visualization tools and improved support for the mobile web. We also describe access to data files, web services and open access software components to enable software developers to more effectively mine the PDB archive and related annotations. Our efforts are aimed at expanding the role of 3D structure in understanding biology and medicine

    "You should go so that others can come"; The Role of Facilities in Determining an Early Departure after Childbirth in Morogoro Region, Tanzania.

    Tanzania is among ten countries that account for a majority of the world's newborn deaths. However, data on time-to-discharge after facility delivery, receipt of postpartum messaging by time to discharge and women's experiences in the time preceding discharge from a facility after childbirth are limited. Household survey of 1267 women who delivered in the preceding 2-14 months; in-depth interviews with 24 women, 12 husbands, and 5 community elders. Two-thirds of women with vaginal, uncomplicated births departed within 12 h; 90 % within 24 h, and 95 % within 48 h. Median departure times varied significantly across facilities (hospital: 23 h, health center: 10 h, dispensary: 7 h, p < 0.001). Quantitative and qualitative data highlight the importance of type of facility and facility amenities in determining time-to-discharge. In multiple logistic regression, level of facility (hospital, health center, dispensary) was the only significant predictor of early discharge (p = 0.001). However across all types of facilities a majority of women depart before 24 h ranging from hospitals (54 %) to health centers (64 %) to dispensaries (74 %). Most women who experienced a delivery complication (56 %), gave birth by caesarean section (90 %), or gave birth to a pre-term baby (70 %) stayed longer than 24 h. Reasons for early discharge include: facility practices including discharge routines and working hours and facility-based discomforts for women and those who accompany them to facilities. Provision of postpartum counseling was inadequate regardless of time to discharge and regardless of type of facility where delivery occurred. Our quantitative and qualitative findings indicate that the level of facility care and comforts existing or lacking in a facility have the greatest effect on time to discharge. This suggests that individual or interpersonal characteristics play a limited role in deciding whether a woman would stay for shorter or longer periods. Implementation of a policy of longer stay must incorporate enhanced postpartum counseling and should be sensitive to women's perceptions that it is safe and beneficial to leave hospitals soon after birth

    An optimised tissue disaggregation and data processing pipeline for characterising fibroblast phenotypes using single-cell RNA sequencing

    Get PDF
    Single-cell RNA sequencing (scRNA-Seq) provides a valuable platform for characterising multicellular ecosystems. Fibroblasts are a heterogeneous cell type involved in many physiological and pathological processes, but remain poorly-characterised. Analysis of fibroblasts is challenging: these cells are difficult to isolate from tissues, and are therefore commonly under-represented in scRNA-seq datasets. Here, we describe an optimised approach for fibroblast isolation from human lung tissues. We demonstrate the potential for this procedure in characterising stromal cell phenotypes using scRNA-Seq, analyse the effect of tissue disaggregation on gene expression, and optimise data processing to improve clustering quality. We also assess the impact of in vitro culture conditions on stromal cell gene expression and proliferation, showing that altering these conditions can skew phenotypes

    The data collection for the interview study is funded by NHS Grampian Endowments, and the costs of the interview transcriptions and eDelphi licences will be paid by the Arcobaleno Cancer Trust. Neither funder had any role in the design of the study. All other parts of the study are currently unfunded. The research team is not personally reimbursed for their time and efforts apart from research input by SD, which is financed by Swedish government funding of clinical research (ALF).Peer reviewedPublisher PD

    First observations of Weddell seals foraging in sponges in Erebus Bay, Antarctica

    Get PDF
    Attaching cameras to marine mammals allows for first-hand observation of underwater behaviours that may otherwise go unseen. While studying the foraging behaviour of 26 lactating Weddell seals (Leptonychotes weddellii) in Erebus Bay during the austral spring of 2018 and 2019, we witnessed three adults and one pup investigating the cavities of Rossellidae glass sponges, with one seal visibly chewing when she removed her head from the sponge. To our knowledge, this is the first report of such behaviour. While the prey item was not identifiable, some Trematomus fish (a known Weddell seal prey) use glass sponges for shelter and in which to lay their eggs. Three of the four sponge foraging observations occurred around 13:00 (NZDT). Two of the three sponge foraging adults had higher-than-average reproductive rates, and the greatest number of previous pups of any seal in our study population, each having ten pups in 12 years. This is far higher than the study population average of three previous pups (± 2.6 SD). This novel foraging strategy may have evolved in response to changes in prey availability, and could offer an evolutionary advantage to some individuals that exploit prey resources that others may not. Our observations offer new insight into the foraging behaviours of one of the world’s most studied marine mammals. Further research on the social aspects of Weddell seal behaviour may increase our understanding of the extent and mechanisms of behavioural transfer between conspecifics. Research into the specific foraging behaviour of especially successful or experienced breeders is also warranted

    Spectacles of intimacy? Mapping the moral landscape of teenage social media

    Get PDF
    This paper explores young people's expressed concerns about privacy in the context of a highly mediated cultural environment, mapping social media practices against axes of visibility and participation. Drawing on interdisciplinary conceptual resources from both the humanities and social sciences, we use ‘spectacles of intimacy’ to conceptualise breaches of privacy, mapping an emergent moral landscape for young people that moves beyond concerns with e-safety to engage with the production and circulation of audiences and value. The paper draws on data from a methodological innovation project using multi-media and mixed methods to capture lived temporalities for children and young people. We present a model that captures a moral landscape shaped by emotional concerns about social media, the affordances of those media and affective discourses emerging from young people's use of the media

    Neuroliberalism:Cognition, context, and the geographical bounding of rationality

    Get PDF
    Focusing on the rise of the behavioural sciences within the design and implementation of public policy, this paper introduces the concept of neuroliberalism and suggests that it could offer a creative context within which to interpret related governmental developments. Understanding neuroliberaism as a system of government that targets the more-than rational aspects of human behaviour, this paper considers the particular contribution that geographical theories of context and spatial representation can make to a critical analysis of this evolving governmental project.authorsversionPeer reviewe
