Épistémologie d’une recherche engagée vers la solidarité
Authors: Fumeaux Carole 
Published: December 2024

Sur le chemin d’une thèse en sciences de l’éducation qui s’intéresse à la scolarisation des élèves migrants, la question se pose de comment choisir et adopter un point de vue épistémologique ainsi qu’une méthodologie cohérents avec l’objet et les attentes de la recherche. Ce choix s’inscrit aussi dans le souci de favoriser une approche interculturelle, se proposant de revisiter la diversité en contribuant à une gestion humaine de celle-ci. Plus précisément, lorsque l’on s’interroge sur la pertinence des dispositifs éducatifs non inclusifs – cette réflexion ayant été suscitée par l’ouverture d’une école réservée aux élèves allophones – il y a lieu de considérer quels sont les présupposés cognitifs et les pratiques de recherche auxquels ces dispositifs font écho. Cet article revient ainsi sur ce parcours d’exploration scientifique et questionne le lien entre le « nous » et le « je », entre scientificité et engagement social. Afin d’élargir les champs du possible, nous choisissons de reconsidérer constamment les concepts permettant d’appréhender la réalité, par une approche compréhensive, intuitive et réflexive, voyant l’écriture comme un levier vers l’action. En préservant l’inattendu de la vie, nous appréhendons les cas particuliers, donnant accès au monde qui nous entoure. Dans la perspective de soutenir un engagement responsable, nous défendons la posture d’une chercheuse solidaire : en envisageant la diversité sur des continuums, nous voulons nous situer nous-mêmes au sein de ces écarts, et de là tenter de la comprendre. Alors, au coeur des interactions construisant la réalité, cette diversité se précise et affiche des bords mouvants, amenant à passer de la perception d’entités séparées à celle d’une solidarité ontologique, ouvrant la porte de l’hospitalité. Dans cette embrasure, la notion d’inclusion se dévoile aussi sous un autre angle et elle demandera ainsi à être revisitée.
Igome Graphs Suggest the Changes in the IgM and IgG Repertoires in Antiphospholipid Syndrome Are in Part Idiotypically Defined

Published: November 2024

Antiphospholipid Syndrome (APS) is characterized by the persistence of high-affinity antiphospholipid antibodies, manifesting clinically as pregnancy complications, thrombosis, or neurological symptoms. This study explores the changes in the IgM and IgG antibody repertoires in APS patients using igome graphs, which represent antibody repertoires through peptide libraries selected from phage display on the complete immunoglobulin fraction of the serum. Serum samples from healthy women and APS patients were processed to isolate IgM and IgG fractions, which were then used for phage selection and next-generation sequencing. Peptide sequences were analyzed using graph representation, clustering, and spectral embedding to identify significant differences between the repertoires. The study revealed that while IgM repertoires in APS patients exhibit a loss of public reactivities, the IgG repertoires do not follow this trend. Three orthogonal sequence motifs were identified in the IgM and IgG repertoires, suggesting potential idiotypic interactions. These findings highlight the intricate mechanisms of antibody selection and cross-reactivity in APS, offering insights into potential therapeutic approaches. The study underscores the importance of system-level analysis in understanding immune mechanisms and suggests that idiotypic interactions, though complex, could play a crucial role in APS pathogenesis.

Published: November 2024

The morphological characteristics of a river basin govern its hydrological response to a considerable extent and it also represents its attributes, which may be employed in synthesizing its hydrological behaviour. Morphological study of the river basin explicit its vulnerability to get erosion. The study area is in the Southern part of Gujarat at 73.20’ to 74.00’ East Longitude and 21.20’ to 22.00’ North Latitude and 140 m Altitude covering regions of Narmada, Vadodara, Surat district, the area has semi-arid climate with erratic rainfall of around 1205 mm. The catchment area of the Karjan River basin is about 1538.38 km2. To check the vulnerability regarding the soil erosion at sub watershed levels for the Karjan river basin, it was bifurcated in to 13 sub watersheds. The morphometric analysis was carried out for all the sub-watersheds, individually. Following standard procedure morphometric analysis was done using linear aspects, aerial aspects. Important 15 morphological parameters for Karjan river basin watershed were calculated using spatial resolution of 30 m DEM in ArcMap software. There were 13 sub-watersheds were delineated in the Karjan river basin i.e. 5D1A6a, 5D1A6b, 5D1A6c, 5D1A6d, 5D1A6e, 5D1A6f, 5D1A6g, 5D1A6h, 5D1A6i, 5D1A6j, 5D1A6k, 5D1A6l and 5D1A6m. After analysing morphometric characteristics of 13 sub-watersheds, 5D1A6l, 5D1A6k and 5D1A6g sub watersheds fall under Very high priority, 5D1A6m, 5D1A6a, 5D1A6e sub watersheds falls under High priority, 5D1A6b, 5D1A6h, 5D1A6i sub watersheds falls under medium priority, 5D1A6c, 5D1A6d, 5D1A6i sub watersheds falls under Low priority and 5D1A6f falls under Very Low priority to soil erosion class.

Published: November 2024

Introduction: Improvements in transportation has increased the risk of rapid infection transmission within communities and globally during outbreaks. Examples are the Ebola virus disease (EVD) epidemic in West Africa in 2014-2016 and the global COVID-19 pandemic in 2020-2022, that devastated and impacted the lives especially in low- income communities and hard to reach regional areas in high income countries such Australia.
The Objective: of this study is an initial exploration of the psychosocial impact of the COVID-19 pandemic on West African migrants now living in Victoria Australia who experienced the EVD while residing in West Africa.
Methodology: This was a narrative description of proposed cross-sectional mixed methods study. Qualitative component was designed to be individual interviews, while the quantitative would utilize SurveyMonkey©. The study population was focused on West African migrants, over the age of 18 years, living in Victoria, who resided in Ebola affected regions of West Africa during 2014-2016. Statistical analyses are proposed to involve mixed methods.
Data collection methods: include an online survey which constituted closed ended quantitative component and qualitative text based open ended questions. Additional semi structured interviews will be conducted. Summaries from the Survey monkey will be further analysed utilising word cloud. Data from interviews will be transcribed with the aid of a computer and Yin’s five stages of qualitative data analysis will also be utilised on both data analysis before triangulation of findings from text-based questions and interviews.
Expected findings: This study will provide a broad perspective of the impact of COVID-19, amongst West African migrants in Victoria who lived the 2014-2016 Ebola epidemic, an experience that can be valuable to migrants in similar situations globally. The expected findings will highlight how prior exposure to stressful situations and disasters such as what occurs in the case of many migrants and minority groups may influence the mental health, wellbeing and coping strategies of migrants when caught in similar disasters. Similarly, it will aid social support services interventions for mental health especially for similar cohorts during traumatic events. The implication of this study is addition of data to inform healthcare managers and public health authorities about the overlooked determinants of psychosocial distress.

Radiation due to Radon gas and its progeny constitutes 50% of the total background radiation exposure. The odourless, colourless and tasteless property of the gas makes it difficult to detect its presence. It can only be detected when measured using a detector. The radioactive decay of radon has a deterministic effect on human lungs when inhaled. For this reason, the World Health Organization (WHO) grouped radon as a human lung carcinogen. The aim of this study was to estimate the average radon concentration in Nnamdi Azikiwe University. Radon levels were measured in eleven different buildings on the campus using the RD 200 radon-eye detector. The indoor radon concentration was measured in both ground floors and upstairs. The average radon concentration measured on the ground floor was 55.03 ± 9.51 Bq.m-3 and 13.90 ± 3.83 Bq.m-3 on the upper floor. The implication of this result is that a person that spends a total of 2000 hrs/yr in these ground floor locations will be exposed to an average effective dose of 0.38 mSv.y-1, while a worker that spends equal time in the upstairs locations will accumulate an average of 0.096 mSv.y-1. Generally, the mean radon concentration in the campus was measured to be 36.34 Bq.m-3 which is a bit lower than the global average of 40 Bq.m-3. The mean annual effective dose for this study was found to be 0.25 mSv.y-1 which is lower than the recommended limit of 1 mSv.y-1. The data from this research offers a reference point for designing the ventilation system of future buildings in the school.

Published: June 2019

Abstract
The deployment of next‐generation sequencing approaches has caused a rapid increase in the number of completely sequenced genomes. As one result of this development, it is feasible to analyze not only single genomes, but also large groups of related genomes in a comparative approach. Whole genome sequencing of type strain genomes also holds huge potential for obtaining a higher resolution phylogenetic and taxonomic classification. In the past 9 years, the EDGAR platform has become one of the most established software tools in the field of comparative genomics. During this time, the software has been continuously improved, and a large number of new analysis features have been added. In recent years, the use of EDGAR for core‐genome‐based phylogenomic/taxonomic analysis has become a main application field of the software. With a focus on generating genome sequences of all type strains of prokaryotic species, the basic 16S rRNA gene sequence phylogeny can be significantly extended to a higher resolution core‐genome‐based taxonomy, and lab work intensive DNA–DNA hybridization (DDH) can be replaced by genome‐sequence‐based indices, which reflect the species borders in the same manner as the DDH.
The web‐based user interface of EDGAR offers all tools required for phylogenomic inter‐ and intraspecies taxonomic analyses as needed for the proposal of novel species. EDGAR calculates core‐genome‐based phylogenetic trees with neighbor‐joining and maximum‐likelihood methods as well as amino acid identity (AAI) and average nucleotide identity (ANI) matrices. Furthermore, it offers convenient visualization features such as Venn diagrams, synteny plots, and a comparative view of the genomic neighborhood of orthologous genes. Recently, the software was extended to include various new features, such as statistical analyses, replicon grouping options, and second‐level analyses of meta gene sets. Thus, the software enables a quick survey of evolutionary relationships and simplifies the process of obtaining new biological insights into the differential gene content of kindred genomes.

EDGAR also provides public databases with precomputed projects providing comparative genomics and phylogenomic results. The platform provides 322 genus‐based public databases comprising 8,079 complete genomes. Besides those genus‐based projects, in this article, we present 226 new public projects that are clustered on the family level and use type strains genomes, which also include draft genomes. These new public projects comprise a further 4,400 genomes. EDGAR is free for academic use and funded as a service by the German Network for Bioinformatics Infrastructure – de.NBI.

Glycocaulis
cells are
dimorphic
and morphologically and behaviorally distinct from each other. One cell type is sessile, nonmotile, and bearing a
prosthecum
; the other cell type is motile due to one polar flagellum. Cells multiply by binary fission. During division, one cell possesses a prosthecum and the other a single polar flagellum. Each appendage occurs at the cell pole opposite the one formed during fission. The flagellated cell develops a prosthecum at the base of the flagellum, secretes adhesive material at its end, attaches to interfaces, and enters the immobile vegetative phase. Cells stain Gram‐negative and are chemoorganotrophic, oligotrophic, and strict aerobes. Species are catalase‐, alkaline phosphatase‐, and leucine arylamidase‐positive but oxidase‐negative; require organic growth factors not satisfied by mixtures of B vitamins and amino acids; require NaCl and neutral to alkaline pH for growth. Growth is inhibited or cells become deformed in media containing 1% (w/v) or more organic material. The genus is characterized by two major

Anti‐retinoblastoma Protein Antibodies: A New Specificity in Systemic Lupus Erythematosus Associated With Protection Against Lupus Nephritis
Authors: Goules Andreas , Li Jessica , Antiochos Brendan , Goldman Daniel W. , Rosen Antony , Petri Michelle , Casciola‐Rosen Livia 
Published: June 2019

ObjectiveRetinoblastoma (Rb) protein is a nuclear protein with several important functions, including the ability to stabilize heterochromatin. Because antibodies against the nucleosome and chromatin are key in systemic lupus erythematosus (SLE), we sought to determine whether Rb was an autoantigen in SLE and to evaluate any associated clinical phenotypes.MethodsSera from 222 patients with SLE from the Hopkins longitudinal cohort were studied. Additional cohorts tested included sera from 100 patients with primary Sjögren syndrome (pSS) (disease controls) evaluated at the Johns Hopkins Jerome L. Greene Sjögren's Center and sera from 36 healthy individuals. Anti‐Rb antibodies were assayed by immunoprecipitation of 35S‐methionine–labeled Rb, which was generated by in vitro transcription/translation. Fisher's exact test was used for the univariate analysis. Multivariable exact logistic regression was used to model for the presence of proteinuria in patients with SLE.ResultsAnti‐Rb antibodies were present in 15 of 222 (6.8%) patients with SLE, in 3 of 100 patients with pSS (3%), and in 0 of 36 healthy individuals. Among patients with SLE, Rb antibodies were strongly negatively associated with proteinuria (P = 0.0031), renal involvement (odds ratio [OR] = 0.11; P = 0.01), and anemia (OR = 0.05; P < 0.0001) and were positively associated with stroke (OR = 7.65; P = 0.05). The negative association with lupus nephritis held true in multivariate models (adjusted OR = 0.11; P = 0.01).ConclusionAnti‐Rb antibodies are a novel specificity not previously described in SLE. These new data define a possible SLE subset that is protected against renal involvement, is positively associated with stroke, and is not associated with antiphospholipid antibodies.
The Validity, Reliability, Measurement Error, and Minimum Detectable Change of the 30‐Second Fast‐Paced Walk Test in Persons with Knee Osteoarthritis: A Novel Test of Short‐Distance Walking Ability
Authors: Hoglund Lisa T. , Folkins Eric , Pontiggia Laura , Knapp Michael W. 
Published: June 2019

ObjectiveTo develop and establish the reliability, validity, measurement error, and minimum detectable change of a novel 30‐second fast‐paced walk test (30SFW) in persons with knee osteoarthritis (OA) that is easy to administer and can quantify walking performance in persons of all abilities.MethodsTwenty females with symptomatic knee OA (mean age [SD] 58.30 [8.05] years) and 20 age‐ and sex‐matched asymptomatic controls (57.25 [8.71] years) participated in the study. Participants completed questionnaires of demographic and clinical data, the Knee Injury and Osteoarthritis Outcome Score (KOOS), and the 36‐item Short Form Health Survey (SF‐36) followed by 30SFW performance. Participants returned 2‐7 days later and performed the 30SFW again.ResultsThe knee OA group reported function that was worse than controls (all KOOS subscales; P < 0.0001). The 30SFW intrarater and interrater reliability were excellent [ICC(2,1) = 0.95‐0.99]. Knee OA participants walked a shorter distance in the 30SFW than controls (mean [SD]: OA 44.4 m [9.5 m]; control 58.1 m [7.8 m]; P < 0.0001). Positive strong correlations were found between the 30SFW and the KOOS–Activity of Daily Living, SF‐36‐Physical Functioning, and SF‐36‐Physical Health Composite scores (P < 0.0001). A nonsignificant, weak correlation between 30SFW and SF‐36‐Mental Health scores was present (r = 0.32, P = 0.05).ConclusionThe 30SFW has excellent intrarater and interrater reliability. The 30SFW demonstrated excellent known groups, convergent, and discriminant validity as a measure of short‐distance walking ability in persons with knee OA. Clinicians and researchers should consider using the 30SFW to quantify walking ability in persons with knee OA and assess walking ability change.
