Functional SNP allele discovery (fSNPd): an approach to find highly penetrant, environmental-triggered genotypes underlying complex human phenotypes
Complement is activated in progressive multiple sclerosis cortical grey matter lesions
The symptoms of multiple sclerosis (MS) are caused by damage to myelin and nerve cells in the brain and spinal cord. Inflammation is tightly linked with neurodegeneration, and it is the accumulation of neurodegeneration that underlies increasing neurological disability in progressive MS. Determining pathological mechanisms at play in MS grey matter is therefore a key to our understanding of disease progression

Seeking legitimacy through CSR: Institutional Pressures and Corporate Responses of Multinationals in Sri Lanka
Arguably, the corporate social responsibility (CSR) practices of multinational enterprises (MNEs) are influenced by a wide range of both internal and external factors. Perhaps most critical among the exogenous forces operating on MNEs are those exerted by state and other key institutional actors in host countries. Crucially, academic research conducted to date offers little data about how MNEs use their CSR activities to strategically manage their relationship with those actors in order to gain legitimisation advantages in host countries. This paper addresses that gap by exploring interactions between external institutional pressures and firm-level CSR activities, which take the form of community initiatives, to examine how MNEs develop their legitimacy-seeking policies and practices. In focusing on a developing country, Sri Lanka, this paper provides valuable insights into how MNEs instrumentally utilise community initiatives in a country where relationship-building with governmental and other powerful non-governmental actors can be vitally important for the long-term viability of the business. Drawing on neo-institutional theory and CSR literature, this paper examines and contributes to the embryonic but emerging debate about the instrumental and political implications of CSR. The evidence presented and discussed here reveals the extent to which, and the reasons why, MNEs engage in complex legitimacy-seeking relationships with Sri Lankan institutions
Model of health? Distributed preparedness and multi-agency interventions surrounding UK regional airports
This article was published in the journal, Social Science and Medicine [Š Elsevier]. The definitive version is available at: http://www.sciencedirect.com/science/article/pii/S0277953611006526The liberalisation of the European aviation sector has multiplied paths of entry into the United Kingdom (UK) for the international traveller. These changing mobilities necessitate a reconceptualisation of the border as a series of potentially vulnerable nodes occurring within, and extending beyond, national boundaries. In this paper, we consider the border through the lens of port health, the collective term for various sanitary operations enacted at international transport terminals. In the UK, a critical player in the oversight of port health is the Health Protection Agency (HPA), which became a non-Departmental public body in 2005. A major part of port health is preparedness, a set of techniques aimed at managing, and responding to, emergencies of public health concern. More recently, certain jurisdictions have embarked on public health preparedness work across a number of different geographical scales. Using methods pioneered by the military, this form of âdistributed preparednessâ is of increased interest to social science and medical scholars. With reference to case studies conducted in localities surrounding two UK regional airports following the 2009-10 H1N1 influenza pandemic, we consider the extent to which distributed preparedness as a concept and a set of practices can inform current debates - in the UK, and beyond - concerning interventions at the border âwithinâ
Two-Nucleon Momentum Distributions Measured in 3He(e,e'pp)n
We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic
range. The kinetic energy distribution for `fast' nucleons (p > 250 MeV/c)
peaks where two nucleons each have 20% or less, and the third nucleon has most
of the transferred energy. These fast pp and pn pairs are back-to-back with
little momentum along the three-momentum transfer, indicating that they are
spectators. Experimental and theoretical evidence indicates that we have
measured distorted two-nucleon momentum distributions by striking the third
nucleon and detecting the spectator correlated pair.Comment: 6 pages, 5 figures, submitted to PR
Autism as a disorder of neural information processing: directions for research and targets for therapy
The broad variation in phenotypes and severities within autism spectrum disorders suggests the involvement of multiple predisposing factors, interacting in complex ways with normal developmental courses and gradients. Identification of these factors, and the common developmental path into which theyfeed, is hampered bythe large degrees of convergence from causal factors to altered brain development, and divergence from abnormal brain development into altered cognition and behaviour. Genetic, neurochemical, neuroimaging and behavioural findings on autism, as well as studies of normal development and of genetic syndromes that share symptoms with autism, offer hypotheses as to the nature of causal factors and their possible effects on the structure and dynamics of neural systems. Such alterations in neural properties may in turn perturb activity-dependent development, giving rise to a complex behavioural syndrome many steps removed from the root causes. Animal models based on genetic, neurochemical, neurophysiological, and behavioural manipulations offer the possibility of exploring these developmental processes in detail, as do human studies addressing endophenotypes beyond the diagnosis itself
Community health workers in rural India: analysing the opportunities and challenges Accredited Social Health Activists (ASHAs) face in realising their multiple roles
Background: Globally, there is increasing interest in community health workerâs (CHW) performance; however, there are gaps in the evidence with respect to CHWsâ role in community participation and empowerment. Accredited Social Health Activists (ASHAs), whose roles include social activism, are the key cadre in Indiaâs CHW programme which is designed to improve maternal and child health. In a diverse country like India, there is a need to understand how the ASHA programme operates in different underserved Indian contexts, such as rural Manipur. Methods: We undertook qualitative research to explore stakeholdersâ perceptions and experiences of the ASHA scheme in strengthening maternal health and uncover the opportunities and challenges ASHAs face in realising their multiple roles in rural Manipur, India. Data was collected through in-depth interviews (n = 18) and focus group discussions (n = 3 FGDs, 18 participants). Participants included ASHAs, key stakeholders and community members. They were purposively sampled based on remoteness of villages and primary health centres to capture diverse and relevant constituencies, as we believed experiences of ASHAs can be shaped by remoteness. Data were analysed using the thematic framework approach. Results: Findings suggested that ASHAs are mostly understood as link workers. ASHAâs ability to address the immediate needs of rural and marginalised communities meant that they were valued as service providers. The programme is perceived to be beneficial as it improves awareness and behaviour change towards maternal care. However, there are a number of challenges; the selection of ASHAs is influenced by power structures and poor community sensitisation of the ASHA programme presents a major risk to success and sustainability. The primary health centres which ASHAs link to are ill-equipped. Thus, ASHAs experience adverse consequences in their ability to inspire trust and credibility in the community. Small and irregular monetary incentives demotivate ASHAs. Finally, ASHAs had limited knowledge about their role as an âactivistâ and how to realise this. Conclusions: ASHAs are valued for their contribution towards maternal health education and for their ability to provide basic biomedical care, but their role as social activists is much less visible as envisioned in the ASHA operational guideline. Access by ASHAs to fair monetary incentives commensurate with effort coupled with the poor functionality of the health system are critical elements limiting the role of ASHAs both within the health system and within communities in rural Manipur
