B-Cell Receptor Signaling Is Thought to Be a Bridge between Primary Sjogren Syndrome and Diffuse Large B-Cell Lymphoma
2023
Primary Sjogren syndrome (pSS) is the second most common autoimmune disorder worldwide, which, in the worst scenario, progresses to Non-Hodgkin Lymphoma (NHL). Despite extensive studies, there is still a lack of knowledge about developing pSS for NHL. This study focused on cells’ signaling in pSS progression to the NHL type of diffuse large B-cell lymphoma (DLBCL). Using bulk RNA and single cell analysis, we found five novel pathologic-independent clusters in DLBCL based on cells’ signaling. B-cell receptor (BCR) signaling was identified as the only enriched signal in DLBCL and pSS peripheral naive B-cells or salivary gland-infiltrated cells. The evaluation of the genes in association with …
Brain Modulation by Electric Currents in Fibromyalgia: A Structured Review on Non-invasive Approach With Transcranial Electrical Stimulation
2018
Fibromyalgia syndrome (FMS) is a complex disorder where widespread musculoskeletal pain is associated with many heterogenous symptoms ranging from affective disturbances to cognitive dysfunction and central fatigue. FMS is currently underdiagnosed and often very poorly responsive to pharmacological treatment. Pathophysiology of the disease remains still obscure even if in the last years fine structural and functional cerebral abnormalities have been identified, principally by neurophysiological and imaging studies delineating disfunctions in pain perception, processing and control systems. On such basis, recently, neurostimulation of brain areas involved in mechanism of pain processing and …
Perception des adventices par les agriculteurs, conseillers, techniciens d’expérimentation et chercheurs en France
2019
Une enquête nationale ayant recueilli 1320 réponses (839 analysées dans cet article), dont 56% d'agriculteurs, 26% de conseillers, 14% de techniciens/expérimentateurs et 4% de chercheurs, a permis de sonder leur perception des adventices. Les effets positifs des adventices ont moins d’importance aux yeux des sondés que leurs effets négatifs. Pour les effets négatifs, la perte de rendement (nuisibilité primaire directe) et l’augmentation du stock semencier (nuisibilité secondaire) sont les plus importants. Entre 60% et 80% des personnes enquêtées jugent importants les effets négatifs sur la conduite des travaux agricoles et la perte de qualité la récolte. Les effets positifs « sources de pol…
Anaerobic co-digestion of microalgae and primary sludge in an anaerobic membrane bioreactor for resource recovery (biogas and bionutrients) from urba…
2020
El consumo continuo de energía primaria ha motivado a la comunidad científica a buscar tecnologías que requieran un menor consumo de recursos y fuentes alternativas de energía renovable, que puedan sustituir a los combustibles fósiles. El cultivo de microalgas en combinación con tecnologías anaerobias surgió como una tecnología prometedora y sostenible en el ámbito del tratamiento de aguas residuales. La valorización de la biomasa de microalgas mediante la digestión anaerobia (AD) permite la producción de energía a partir de corrientes de residuos. Dado que la AD de microalgas presenta algunos inconvenientes que obstaculizan la eficiencia del proceso, se ha estudiado la co-digestión anaerob…
Sixth graders evaluating online texts : self-efficacy beliefs predict confirming but not questioning the credibility
2023
This study investigated how sixth graders’ credibility evaluation self-efficacy was associated with their ability to evaluate the credibility of online texts. Students (N = 265, Mage = 12.45) worked in a web-based environment, where they read and evaluated two more credible texts and two less credible texts that required confirming and questioning the texts’ credibility, respectively. Students were asked to evaluate the author’s expertise, the author’s benevolence, and the quality of evidence in each text. They were also asked to assess their credibility evaluation self-efficacy during the task. The structural equation model indicated that students’ self-efficacy was positively associated w…
Classroom effect on primary school students’ self-concept in literacy and mathematics
2019
AbstractAccording to the big-fish-little-pond effect (BFLP) model, high individual academic performance in a particular subject is related to high self-concept in that subject, whereas high average classroom performance has a negative effect on self-concept. In the present study, data from Finnish primary school students in grade 3 (504 students), grade 4 (487 students), and grade 6 (365 students) are used to examine whether the assumptions of the BFLP effect model hold already in primary school. Furthermore, we examined gender differences in BFLP effect. The results showed that as expected students’ high performance in literacy and in mathematics was related to high self-concept in the sam…
Debunking the myth of high achievers in Finnish primary teacher education: first-year preservice teachers’ learning strategies and study success
2022
This study aimed to explore the admitted students of Finnish primary teacher education programmes from the viewpoint of learning strategies, and academic success. An overall view was derived from national register data, which were supplemented with questionnaire data gathered from three teacher education units (N = 216). Primary teacher programmes currently seem to attract and select mediocre secondary school graduates from academic perspective, contrary to previous studies. Furthermore, women enter the programmes with higher exam scores than men and have more success in their studies. Based on their learning strategies, students were divided into subgroups of deep and independent learners,…

Off on the wrong foot : Task avoidance at the outset of primary school anticipates academic difficulties and declining peer acceptance
2021
The present study examined the academic antecedents of declining peer social status. Participants included 545 (311 boys, 234 girls) Finnish students followed from the 1st through the 4th grade (ages 6–8 at outset). Each year, teachers completed assessments of academic task avoidance and students completed standardized measures of reading and math achievement. Acceptance was assayed through peer nominations. Supporting the hypothesized model, the results indicated that a lack of interest and motivation at the outset of primary school leads to a downward spiral of academic difficulties and diminished peer acceptance. Specifically, academic task avoidance in 1st and 2nd grade anticipated decl…
Students' Positive Expectations and Concerns Prior to the School Transition to Lower Secondary School
2020
This mixed-method study examines students' expectations and concerns before transitioning from primary to lower secondary school and the role of students' school-related wellbeing and self-esteem in their concerns. Students reported their beliefs about the forthcoming school transition and filled in a questionnaire assessing school burnout and self-esteem. The results showed that the students had positive expectations comprising comfort, friendships, learning, school environment, increased freedom and teacher -student relations. The students' concerns were mainly related to friendships. Furthermore, results indicated that students who reported concerns about peer relations were likely to ex…
