Diagnostic tests for Niemann-Pick disease type C (NP-C): A critical review

Niemann-Pick disease type C (NP-C) is a neurovisceral lysosomal cholesterol trafficking and lipid storage disorder caused by mutations in one of the two genes, NPC1 or NPC2. Diagnosis has often been a difficult task, due to the wide range in age of onset of NP-C and clinical presentation of the disease, combined with the complexity of the cell biology (filipin) laboratory testing, even in combination with genetic testing. This has led to substantial delays in diagnosis, largely depending on the access to specialist centres and the level of knowledge about NP-C of the physician in the area. In recent years, advances in mass spectrometry has allowed identification of several sensitive plasma biomarkers elevated in NP-C (e.g. cholestane-3β,5α,6β-triol, lysosphingomyelin isoforms and bile acid metabolites), which, together with the concomitant progress in molecular genetic technology, have greatly impacted the strategy of laboratory testing. Specificity of the biomarkers is currently under investigation and other pathologies are being found to also result in elevations. Molecular genetic testing also has its limitations, notably with unidentified mutations and the classification of new variants. This review is intended to increase awareness on the currently available approaches to laboratory diagnosis of NP-C, to provide an up to date, comprehensive and critical evaluation of the various techniques (cell biology, biochemical biomarkers and molecular genetics), and to briefly discuss ongoing/future developments. The use of current tests in proper combination enables a rapid and correct diagnosis in a large majority of cases. However, even with recent progress, definitive diagnosis remains challenging in some patients, for whom combined genetic/biochemical/cytochemical markers do not provide a clear answer. Expertise and reference laboratories thus remain essential, and further work is still required to fulfill unmet needs

Global Assemblages, Resilience, and Earth Stewardship in the Anthropocene

In this paper, we argue that the Anthropocene is an epoch characterized not only by the anthropogenic dominance of the Earth\u27s ecosystems but also by new forms of environmental governance and institutions. Echoing the literature in political ecology, we call these new forms of environmental governance “global assemblages”. Socioecological changes associated with global assemblages disproportionately impact poorer nations and communities along the development continuum, or the “Global South”, and others who depend on natural resources for subsistence. Although global assemblages are powerful mechanisms of socioecological change, we show how transnational networks of grassroots organizations are able to resist their negative social and environmental impacts, and thus foster socioecological resilience

Entanglements of faith: Discourses, practices of care and homeless people in an Italian City of Saints

This is the author accepted manuscript. The final version is available from SAGE via http://dx.doi.org/10.1177/0042098013514620This paper investigates how Catholic-inspired services for homeless people are delivered in Turin, Italy. The purpose is to critically interrogate particular faith-based organisations’ moral discourses on homelessness, and to show how they are enacted through practices of care directed at the homeless subject. The paper contributes to the geographical literature on faith-based organisations addressing its shortcomings – namely the lack of critical and contextual focus on faith-based organisations’ ‘love for the poor’. To address this point, the paper takes a vitalist perspective on the urban and introduces the notion of the ‘entanglements of faith’, which allows an integrated and grounded perspective on faith-based organisations’ interventions. The outcomes of the work suggest that these faith-based organisations propose standardised services that, producing particular assemblages and affective atmospheres, have deep emotional and relational effects on their recipients. Further lines of research are sketched in the conclusions

Tales of Emergence - Synthetic Biology as a Scientific Community in the Making

International audienceThis article locates the beginnings of a synthetic biology network and thereby probes the formation of a potential disciplinary community. We consider the ways that ideas of community are mobilized, both by scientists and policy-makers in building an agenda for new forms of knowledge work, and by social scientists as an analytical device to understand new formations for knowledge production. As participants in, and analysts of, a network in synthetic biology, we describe our current understanding of synthetic biology by telling four tales of community making. The first tale tells of the mobilization of synthetic biology within a European context. The second tale describes the approach to synthetic biology community formation in the UK. The third narrates the creation of an institutionally based, funded 'network in synthetic biology'. The final tale de-localizes community-making efforts by focussing on 'devices' that make communities. In tying together these tales, our analysis suggests that the potential community can be understood in terms of 'movements'--the (re)orientation and enrolment of people, stories, disciplines and policies; and of 'stickiness'--the objects and glues that begin to bind together the various constitutive elements of community

Paroxysmal nocturnal hemoglobinuria (PNH): higher sensitivity and validity in diagnosis and serial monitoring by flow cytometric analysis of reticulocytes

Flow cytometric analysis of GPI-anchored proteins (GPI-AP) is the gold standard for diagnosis of paroxysmal nocturnal hemoglobinuria (PNH). Due to therapy options and the relevance of GPI-deficient clones for prognosis in aplastic anaemia detection of PNH is gaining importance. However, no generally accepted standard has been established. This study analysed the usefulness of a flow cytometric panel with CD58, CD59 on reticulocytes and erythrocytes, CD24/CD66b and CD16, FLAER on granulocytes and CD14, and CD48 on monocytes. Actual cut-off (mean + 2 SD) for GPI-deficient cells was established in healthy blood donors. We studied 1,296 flow cytometric results of 803 patients. Serial monitoring was analysed during a median follow-up of 1,039 days in 155 patients. Of all, 22% and 48% of 155 follow-up patients. showed significant GPI-AP-deficiency at time of initial analyses. During follow-up in 9%, a new PNH diagnosis, and in 28%, a significant change of size or lineage involvement was demonstrated. Highly significant correlations for GPI-AP deficiency were found within one cell lineage (r2 = 0.61–0.95, p < 0.0001) and between the different cell lineages (r2 = 0.49–0.88, p < 0.0001). Especially for detection of small GPI-deficient populations, reticulocytes and monocytes proved to be sensitive diagnostic tools. Our data showed superiority of reticulocyte analyses compared with erythrocyte analyses due to transfusion and hemolysis independency especially in cases with small GPI-deficient populations. In conclusion, a screening panel of at least two different GPI-AP markers on granulocytes, erythrocytes, and reticulocytes provides a simple and rapid method to detect even small GPI-deficient populations. Among the markers in our panel, CD58 and CD59 on reticulocytes, CD24/66b, and eventually FLAER on granulocytes as well as CD14 on monocytes were most effective for flow cytometric diagnosis of GPI deficiency

Business opportunities analysis using GIS: the retail distribution sector

[EN] The retail distribution sector is facing a difficult time as the current landscape is characterized by ever-increasing competition. In these conditions, the search for an appropriate location strategy has the potential to become a differentiating and competitive factor. Although, in theory, an increasing level of importance is placed on geography because of its key role in understanding the success of a business, this is not the case in practice. For this reason, the process outlined in this paper has been specifically developed to detect new business locations. The methodology consists of a range of analyzes with Geographical Information Systems (GISs) from a marketing point of view. This new approach is called geomarketing. First, geodemand and geocompetition are located on two separate digital maps using spatial and non-spatial databases. Second, a third map is obtained by matching this information with the demand not dealt with properly by the current commercial offer. Third, the Kernel density allows users to visualize results, thus facilitating decision-making by managers, regardless of their professional background. The advantage of this methodology is the capacity of GIS to handle large amounts of information, both spatial and non-spatial. A practical application is performed in Murcia (Spain) with 100 supermarkets and data at a city block level, which is the highest possible level of detail. This detection process can be used in any commercial distribution company, so it can be generalized and considered a global solution for retailers.Roig Tierno, H.; Baviera-Puig, A.; Buitrago Vera, JM.

Symbolic meanings and e-learning in the workplace: The case of an intranet-based training tool

This article contributes to the debate on work-based e-learning, by unpacking the notion of ‘the learning context’ in a case where the mediating tool for training also supports everyday work. Users’ engagement with the information and communication technology tool is shown to reflect dynamic interactions among the individual, peer group, organizational and institutional levels. Also influential are professionals’ values and identity work, alongside their interpretations of espoused and emerging symbolic meanings. Discussion draws on pedagogically informed studies of e-learning and the wider organizational learning literature. More centrally, this article highlights the instrumentality of symbolic interactionism for e-learning research and explores some of the framework’s conceptual resources as applied to organizational analysis and e-learning design. </jats:p

The moral work of subversion

This article critically reconsiders dominant understandings of morality and subversion within organizations. Existing organizational literature does not adequately address the important productive role of morality for producing and justifying everyday subversive practices as well as the use of subversion to legitimate power relations and dominant values. Drawing upon interactionist insights, we develop a practice-based account of morality, highlighting the means through which subversion retroactively legitimates the diverse range of actions performed by organizational subjects. This form of retrospective reasoning, which we term ‘moralization’, serves as an important resource for subjects to actively negotiate the often competing moral and practical demands placed on them as organizational subjects. Consequently, we position subversion as an important means of accomplishing, legitimating and preserving a given organizational order, rather than a ‘common sense’ view that subversion necessarily subverts organizational values. In doing so, we make explicit the ‘positive’ function of rule-bending for processes of organizational control
