L’ANVIE : pour rapprocher sciences de l’homme et entreprise

L’ANVIE (Association Nationale pour la Valorisation Interdisciplinaire de la recherche en sciences de l’homme et de la société auprès des Entreprises) a été créée en 1991 à l’initiative du ministère de la Recherche et de l’Espace. Elle a vocation à développer et à dynamiser les relations entre sciences sociales et entreprises. Les conditions sont favorables pour le dialogue et la coopération Cette initiative, qui vient compléter un dispositif institutionnel déjà consistant, cherche à consolid..

2019 International Aircraft Cabin Air Conference : Conference Proceedings – Presentations

The International Aircraft Cabin Air Conferences are developing into a series of conferences organized every two years. The conferences are mapping the business, regulatory and technical solutions to aircraft cabin air contamination. The conferences in 2017 and 2019 provided networking opportunities for those seeking to understand the subject of contaminated air, the flight safety implications, the latest scientific and medical evidence investigating the contaminated air debate and the solutions available to airlines and aircraft operators. The two conferences held so far have been the most in-depth conferences ever on the topic of aircraft cabin air contamination. In total 30 presentations were given at the 2019 International Aircraft Cabin Air Conference (ACA 2019). This document contains the 25 presentations provided by the authors. It combines the presentations into one PDF for further dissemination and archiving

Bridging Restoration Science and Practice: Results and Analysis of a Survey from the 2009 Society for Ecological Restoration International Meeting

Developing and strengthening a more mutualistic relationship between the science of restoration ecology and the practice of ecological restoration has been a central but elusive goal of SERI since its inaugural meeting in 1989. We surveyed the delegates to the 2009 SERI World Conference to learn more about their perceptions of and ideas for improving restoration science, practice, and scientist/practitioner relationships. The respondents' assessments of restoration practice were less optimistic than their assessments of restoration science. Only 26% believed that scientist/practitioner relationships were “generally mutually beneficial and supportive of each other,” and the “science–practice gap” was the second and third most frequently cited category of factors limiting the science and practice of restoration, respectively (“insufficient funding” was first in both cases). Although few faulted practitioners for ignoring available science, many criticized scientists for ignoring the pressing needs of practitioners and/or failing to effectively communicate their work to nonscientists. Most of the suggestions for bridging the gap between restoration science and practice focused on (1) developing the necessary political support for more funding of restoration science, practice, and outreach; and (2) creating alternative research paradigms to both facilitate on-the-ground projects and promote more mutualistic exchanges between scientists and practitioners. We suggest that one way to implement these recommendations is to create a “Restoration Extension Service” modeled after the United States Department of Agriculture's Cooperative Extension Service. We also recommend more events that bring together a fuller spectrum of restoration scientists, practitioners, and relevant stakeholders.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79142/1/j.1526-100X.2010.00743.x.pd

Molecular insights into amyloid regulation by membrane cholesterol and sphingolipids: common mechanisms in neurodegenerative diseases

Alzheimer, Parkinson and other neurodegenerative diseases involve a series of brain proteins, referred to as ‘amyloidogenic proteins’, with exceptional conformational plasticity and a high propensity for self-aggregation. Although the mechanisms by which amyloidogenic proteins kill neural cells are not fully understood, a common feature is the concentration of unstructured amyloidogenic monomers on bidimensional membrane lattices. Membrane-bound monomers undergo a series of lipid-dependent conformational changes, leading to the formation of oligomers of varying toxicity rich in β-sheet structures (annular pores, amyloid fibrils) or in α-helix structures (transmembrane channels). Condensed membrane nano- or microdomains formed by sphingolipids and cholesterol are privileged sites for the binding and oligomerisation of amyloidogenic proteins. By controlling the balance between unstructured monomers and α or β conformers (the chaperone effect), sphingolipids can either inhibit or stimulate the oligomerisation of amyloidogenic proteins. Cholesterol has a dual role: regulation of protein–sphingolipid interactions through a fine tuning of sphingolipid conformation (indirect effect), and facilitation of pore (or channel) formation through direct binding to amyloidogenic proteins. Deciphering this complex network of molecular interactions in the context of age- and disease-related evolution of brain lipid expression will help understanding of how amyloidogenic proteins induce neural toxicity and will stimulate the development of innovative therapies for neurodegenerative diseases

Sideroflexin 3 is an α-synuclein-dependent mitochondrial protein that regulates synaptic morphology

α-Synuclein plays a central role in Parkinson's disease, where it contributes to the vulnerability of synapses to degeneration. However, the downstream mechanisms through which α-synuclein controls synaptic stability and degeneration are not fully understood. Here, comparative proteomics on synapses isolated from α-synuclein(−/−) mouse brain identified mitochondrial proteins as primary targets of α-synuclein, revealing 37 mitochondrial proteins not previously linked to α-synuclein or neurodegeneration pathways. Of these, sideroflexin 3 (SFXN3) was found to be a mitochondrial protein localized to the inner mitochondrial membrane. Loss of SFXN3 did not disturb mitochondrial electron transport chain function in mouse synapses, suggesting that its function in mitochondria is likely to be independent of canonical bioenergetic pathways. In contrast, experimental manipulation of SFXN3 levels disrupted synaptic morphology at the Drosophila neuromuscular junction. These results provide novel insights into α-synuclein-dependent pathways, highlighting an important influence on mitochondrial proteins at the synapse, including SFXN3. We also identify SFXN3 as a new mitochondrial protein capable of regulating synaptic morphology in vivo

Hodgkin's lymphoma presenting with heart failure: a case report

<p>Abstract</p> <p>Introduction</p> <p>Cardiac involvement in malignant lymphoma is one of the least investigated subjects in oncology. This article reports a case of cardiac involvement in Hodgkin's lymphoma which presented as heart failure.</p> <p>Case presentation</p> <p>We report the case of an 8-year-old Afghan girl with Hodgkin's lymphoma. The disease presented with systemic signs and symptoms, including abdominal distension, weakness, pallor, chills, fever, generalized edema, hepatosplenomegaly and generalized lymphadenopathy, as well as signs of heart failure. Test results showed a rare form of heart metastasis.</p> <p>Conclusion</p> <p>We report a case of Hodgkin's lymphoma with metastasis to the heart, detected premortem. Although the involvement of the heart in a malignancy is relatively common, premortem detection is unusual and only few studies have reported it in the literature.</p
