P059 Le lipido-récepteur intestinal CD36 et sa cascade de signalisation ERK1/2 dépendante contrôle la synthèse des chylomicrons
2013
International audience; Introduction et but de l’étude. – L’intestin est capable d’adapter sa capacité d’absorption à la teneur en lipide du régime. Cette adaptation implique un système de détection des lipides au niveau entérocytaire. Le CD36, qui est une glycoprotéine transmembranaire liant avec une forte affinité les acides gras à longue chaîne (AGLC), pourrait jouer ce rôle. En effet, ex vivo, la présence d’AGLC est associée à une activation de la voie ERK1/2 et conduit à l’induction de protéines clés du métabolisme intestinal des lipides : l’ApoB48 et la MTP. Cette régulation est CD36 dépendante (Tran et al. 2011). De plus, la déficience de CD36 est associée chez l’Homme et l’animal à …
Third International Congress of Histochemistry and Cytochemistry
1968
The tissue distribution of enzymatic activities in intestinal metaplasia stomachs exhibiting chronic gastritis was compared histochemically with that of the small intestine in man.
C4 ‐dicarboxylates and l ‐aspartate utilization by Escherichia coli K‐12 in the mouse intestine: l ‐aspartate as a major substrate for fumarate respi…
2021
C4-dicarboxylates, such as fumarate, L-malate and L-aspartate represent substrates for anaerobic growth of Escherichia coli by fumarate respiration. Here, we determined whether C4-dicarboxylate metabolism as well as fumarate respiration contribute to colonization of the mammalian intestinal tract. Metabolite profiling revealed that the murine small intestine contained high and low levels of L-aspartate and L-malate, respectively, whereas fumarate was nearly absent. Under laboratory conditions, addition of C4-dicarboxylate at concentrations corresponding to the levels of the C4-dicarboxylates in the small intestine (2.6 mMol/kg dry weight) induced the dcuBp-lacZ reporter gene (67% of maximal…
Intestinal CD36. A lipid-sensor involved in the processing of chylomicrons in rodents
2011
International audience; CD36 is a multifunctional glycoprotein which binds nanomolar concentrations of long-chain fatty acids (LCFA) and is highly expressed on the luminal surface of enterocytes. Despite of its implication in oleoylethanolamide (OEA) and chylomicron synthesis, CD36 function in small intestine remains incompletely understood. Our in vivo data demonstrated that CD36 gene deletion in mice did not affect intestinal LCFA uptake. CD36 protein disappeared early from the luminal side of intestinal villi during the post-prandial period but only when the diet contained lipids. This drop was significant 1 h after a lipid supply and was associated with ubiquitination of CD36. Using CHO…
Acceptability of the e-authentication in higher education studies: views of students with special educational needs and disabilities
2021
AbstractTrust-based e-assessment systems are increasingly important in the digital age for both academic institutions and students, including students with special educational needs and disabilities (SEND). Recent literature indicates a growing number of studies about e-authentication and authorship verification for quality assurance with more flexible modes of assessment. Yet understanding the acceptability of e-authentication systems among SEND students is underexplored. This study examines SEND students’ views about the use of e-authentication systems, including perceived advantages and disadvantages of new technology-enhanced assessment. This study aims to shed light on this area by exa…
Looking towards the Future of Language Assessment: Usability of Tablet PCs in Language Testing
2016
[EN] This research addresses the change in how the Spanish University Entrance Examination can be delivered in the future. There is a wide acknowledgement that computer tests are very demanding for the delivering institutions which makes computer language testing difficult to implement. However, the use of tablet PCs can facilitate the delivery at even lower cost than the regular computer based language testing. 183 students in their last year of high school took a computer based language test which included reading, writing, listening and speaking. The research aspects were 1) whether they feel at ease with the tablet PC exam; 2) if they felt that visual aspects were accessible and 3) whet…
Actitudes docentes hacia los ejercicios de la Prueba de Acceso a la Universidad informatizada
2017
Resumen El presente artículo forma parte de la investigación desarrollada en el proyecto Paulex Universitas con la intención de obtener información sobre los ítems más aceptados por los profesores de 2º de Bachillerato de cara al inicio de la fase de pruebas para examinar la viabilidad de la puesta en funcionamiento de la Prueba de Acceso a la Universidad (PAU) asistida por ordenador en España y, más específicamente, los siguientes aspectos: la posibilidad de automatización de la prueba, las tipologías de ejercicios más populares entre los profesores y la relación entre las mismas. Un total de 214 profesores respondieron a un cuestionario diseñado según el método Delphi, destinado a averigu…
Progress Checking for Dummies
2018
Verification of progress properties is both conceptually and technically significantly more difficult than verification of safety and deadlock properties. In this study we focus on the conceptual side. We make a simple modification to a well-known model to demonstrate that it passes progress verification although the resulting model is intuitively badly incorrect. Then we point out that the error can be caught easily by adding a termination branch to the system. We compare the use of termination branches to the established method of addressing the same need, that is, weak fairness. Then we discuss another problem that may cause failure of catching progress errors even with weak fairness. Fi…
Patterns of domain-specific learning among medical undergraduate students in relation to confidence in their physiology knowledge : insights from a p…
2022
Research FocusThe promotion of domain-specific knowledge is a central goal of higher education and, in the field of medicine, it is particularly essential to promote global health. Domain-specific knowledge on its own is not exhaustive; confidence regarding the factual truth of this knowledge content is also required. An increase in both knowledge and confidence is considered a necessary prerequisite for making professional decisions in the clinical context. Especially the knowledge of human physiology is fundamental and simultaneously critical to medical decision-making. However, numerous studies have shown difficulties in understanding and misconceptions in this area of knowledge. Therefo…
Generation terrorists : Manic street preachers -yhtyeen musiikin poliittisuus ja poliittisuuden muutos vuosina 1992-2001
2011
Tutkimuksen tehtävänä on selvittää, kuinka poliittiset vaikutuspyrkimykset ilmenevät Manic Street Preachers -yhtyeen vuosien 1992-2001 singlejulkaisujen musiikissa eli sanoituksissa, sävellyksissä, esityksessä ja levytyksessä. Tarkoituksena on tarkastella myös, miten yhtye edustaa protestilaulugenreä ja kuinka yhtyeen poliittisuus on muuttunut kaupallisen menestymisen sekä ajallisen muutoksen myötä. Lähestyn politiikkaa ja siihen liittyvää valta-aspektia tässä tutkimuksessa vaikutusvallan näkökulmasta. Sanoituksissa ilmenevää vaikutusvaltaa erittelen Chaïm Perelmanin argumentaatiotekniikkojen jaottelun avulla. Sanoitusanalyysiin yhdistän analyysin musiikillisista korostuselementeistä, jotka…
