Characterization of Acanthamoeba-microsphere association by multiparameter flow cytometry and confocal microscopy

Background: Acanthamoebae, in common with other protozoa, readily endocytose particulate material, which in turn may lead to the spread of infectious disease. Methods: Evaluation and quantification of plain and carboxylate FITC-microsphere association with acanthamoebal trophzoites was undertaken using a combination of flow cytometry and confocal microscopy. Trophozoites from strains and species of Acanthamoeba were exposed to plain and carboxylate FITC-microspheres. Microsphere size and aspects such as trophozoite starvation, maturity, and exposure to metabolic inhibitors were assessed. Results: All species and strains of Acanthamoeba readily endocytosed plain and carboxylate microspheres. Starving trophozoites significantly increased binding and potential ingestion of microspheres, whereas trophozoites of increasing maturity lost such abilities. Trophozoites showed a significant preference for 2.0- and 3.0-μm-diameter microspheres when compared with other sizes, which in turn could occupy much of the cytoplasm. The physiological inhibitors sodium azide, 2,4-clinitrophenol, and cytochalasin B reduced microsphere association with trophozoites; however, some microspheres still bound and associated with trophozoites after inhibitor exposure, a manifestation of both active and inactive agent involvement in microsphere endocytosis. Conclusions: Even though the origins of microsphere binding by acanthamoebal trophozoite remains shrouded, the combination of flow cytometry and confocal microscopy supported synergistic quantification and qualification of trophozoite-microsphere endocytosis. © 2006 International Society for Analytical Cytology.

The devil is in the detail:tobacco industry political influence in the Dutch implementation of the 2001 EU Tobacco Products Directive

Introduction - The Dutch implementation of the black border provision in the 2001 European Union Tobacco Products Directive (TPD) is studied to examine the implications of tobacco industry involvement in the implementation phase of the policy process. Methods - A qualitative analysis was conducted of Dutch government documents obtained through Freedom of Information Act requests, triangulated with in-depth interviews with key informants and secondary data sources (publicly available government documents, scientific literature, and news articles). Results - Tobacco manufacturers’ associations were given the opportunity to set implementation specifications via a fast-track deal with the government. The offer of early implementation of the labelling section of the TPD was used as political leverage by the industry, and underpinned by threats of litigation and arguments highlighting the risks of additional public costs and the benefits to the government of expediency and speed. Ultimately, the government agreed to the industry's interpretation, against the advice of the European Commission. Conclusions - The findings highlight the policy risks associated with corporate actors’ ability to use interactions over technical product specifications to influence the implementation of health policy and illustrate the difficulties in limiting industry interference in accordance with Article 5.3 of the Framework Convention on Tobacco Control (FCTC). The implementation phase is particularly vulnerable to industry influence, where negotiation with industry actors may be unavoidable and the practical implications of relatively technical considerations are not always apparent to policymakers. During the implementation of the new TPD 2014/40/EU, government officials are advised to take a proactive role in stipulating technical specifications.

Women in Europe between the wars:politics, culture and society

The central aim of this interdisciplinary book is to make visible the intentionality behind the 'forgetting' of European women's contributions during the period between the two world wars in the context of politics, culture and society. It also seeks to record and analyse women's agency in the construction and reconstruction of Europe and its nation states after the First World War, and thus to articulate ways in which the writing of women's history necessarily entails the rewriting of everyone's history. By showing that the erasure of women's texts from literary and cultural history was not accidental but was ideologically motivated, the essays explicitly and implicitly contribute to debates surrounding canon formation. Other important topics are women's political activism during the period, antifascism, the contributions made by female journalists, the politics of literary production, genre, women's relationship with and contributions to the avant-garde, women's professional lives, and women's involvement in voluntary associations. In bringing together the work of scholars whose fields of expertise are diverse but whose interests converge on the inter-war period, the volume invites readers to make connections and comparisons across the whole spectrum of women's political, social, and cultural activities throughout Europe.

The big 4 in Bangladesh:caught between the global and the local

Purpose- This article explores the work practices of Big 4 firms in Bangladesh with the aim of exploring the extent to which Global Professional Service Firms can be thought of as being genuinely ‘global’. Methodology/Approach- Interviews were undertaken with the vast majority of Big 4 partners in Bangladesh. These interviews explored a number of themes related to the professional service work context in Bangladesh and the relationship between local and global firms. Findings- The central finding of this paper is that although the Big 4 have a long-established presence in Bangladesh, local societal factors heavily influence the realities of work for accountants there. In most cases the Big 4 firms establish correspondent firms (instead of full member firms) in Bangladesh and tend to offer restricted service lines. Additionally, the paper identifies professional, commercial and cultural barriers to greater Big 4 involvement in the local market. Conceptually, the chief contribution of this paper is to explore how the effects of globalising capitalism and standardised ‘best practices’ in global professional service work are mediated through the societal effects of Bangladeshi society, resulting in the Big 4 having only a tentative presence in the Bangladeshi market. Research implications- The findings cast doubt on the extent to which self-styled Global Professional Service firms are truly ‘global’ in nature. Future work examining the Big 4, or accounting more generally, in the context of globalization, would do well to pay greater attention to the experience of professionals in emerging markets. Originality/Value- Whilst there has been much work looking at accounting and accountants in the context of globalization, this work has tended to privilege ‘core’ western empirical settings. Very little is known about Professional Service Firms in ‘peripheral’ or emerging markets. Furthermore, this study extends the application of the System, Society and Dominance framework by mapping the interactions and dynamics of these three sources of influence in the setting of PSFs.

An examination of the UK community pharmacist's role in facilitating patient self-management of cardiovascular disease through lifestyle behaviours

The progression of cardiovascular disease (CVD) is largely modifiable through lifestyle behaviours. UK pharmacists are contractually obliged to facilitate patient self-management of chronic conditions such as CVD. Pharmacists are easily accessible health professionals who are well placed to identify “at risk” patients through medication regimes. Research has identified varying attitudes towards and levels of involvement in pharmacist-led health promotion activity. Given the diverse and exploratory nature of the work, a pragmatic, mixed methods approach was used to explore community pharmacists’ role in facilitating patient self-management of CVD. The thesis presents four studies: a qualitative study with pharmacists; a cross sectional questionnaire of community pharmacists; a systematic review and a qualitative study with patients with CVD. The qualitative study with pharmacists gave an insight into pharmacists’ experiences of giving patients with CVD lifestyle advice and the factors underpinning commonly cited barriers to providing public health services. This informed the development of the cross-sectional questionnaire which identified the predictors of pharmacists’ intentions to give two different types of advice to facilitate patient self-management. The systematic review identified a small number of interventions to prepare pharmacists to facilitate patient lifestyle behaviour change and evaluated the theories and behaviour change techniques used in successful interventions; however due to poor study quality and poor reporting of the interventions limited conclusions about the efficacy of the interventions could reliably be drawn. Finally, the qualitative study gave an insight into the experiences of patients with CVD using community pharmacy services and their expectations of the service they receive from community pharmacists. Recommendations about changes to pharmacy policy and practice in order to support pharmacists’ provision of CVD self-management advice are made.

Partnership and organizing:an empirical assessment of two contrasting approaches to union revitalization in the UK

The Trades Union Congress (TUC) in Britain has been advocating two contrasting approaches to union revitalization namely: ‘labour—management partnership’ and ‘union organizing’. Using a case study of a public services union this article examines empirically the prospects of union revival offered by these two contrasting approaches. Public services with relatively high union density should offer better prospects for union revival through partnership. However, the authors’ findings indicate that even in public services, partnership was not associated with management’s support for union recruitment, better facility time provisions for union representatives, lower worker grievances or union membership gains. Rank-and-file organizing, on the other hand, was associated with lower worker grievances, greater worker satisfaction with the union, higher worker involvement in union activities and union membership gains. Overall, the findings question the ‘mutual gains’ assertions of partnership advocates and lend support to the critics of partnership who propose an alternative organizing approach to union revitalization.
