Formation of microbial organic carbonates during the Late Jurassic from the Northern Tethys (Amu Darya Basin, Uzbekistan): implications for Jurassic …

2020

23 pages; International audience; The Late Jurassic was a period of major global carbon cycle perturbations with episodes of anoxia leading to regional accumulation of organic matter in sediments worldwide. The Tubiegatan section (SW Gissar Mountains, Uzbekistan) located in the Northern Tethys, shows atypical organic-rich limestone and marl deposits (up to 6% of total organic carbon) marked by pronounced negative excursions of δ13Ccarb (amplitude of ca. 12‰) and δ13Corg (amplitude of ca. 4‰) recorded during the Middle Oxfordian (Transversarium Zone). A transdisciplinary approach including sedimentology, palynofacies characterization, mineralogy, organic and inorganic geochemistry was carrie…

Implicación de los microARNs en la hipertensión pulmonar idiopática. Regulación farmacológica

2014

La hipertensión pulmonar (HP) es un desorden complejo que se caracteriza por un aumento progresivo de la presión arterial pulmonar, ocasionado por el remodelado de las arterias pulmonares de pequeño calibre, que origina un aumento de resistencias pulmonares y como consecuencia sobrecarga y fallo del ventrículo derecho que puede llevar al fallecimiento del paciente. La Organización mundial de la salud la clasifica en 5 grupos, en nuestro estudio nos hemos centrado en el grupo I, que se caracteriza por la afección de los vasos pulmonares de pequeño calibre, con una presión arterial pulmonar (PAP) media de ≥ 25 mmHg y ausencia de causas secundarias, este así mismo se subdivide en hipertensión …

Dépenses d’enseignement dans les collèges privés et publics et indice de positionnement social : une analyse spatiale et longitudinale

2023

Introduction En France, depuis 1963, date d’instauration de la carte scolaire, l’affectation des élèves dans un collège est fonction de son lieu de résidence. Ainsi, chaque élève est affecté à un collège public à proximité de son domicile. Par essence, cette méthode d’affectation reproduit au sein des collèges la ségrégation résidentielle. La possibilité d’obtenir des dérogations à cette affectation administrative, l’assouplissement de la carte scolaire de 2007, et la liberté de scolariser so...

Giant cell arteritis associated with chronic active Epstein-Barr virus infection

2013

Giant cell arteritis is an inflammatory vasculopathy that preferentially affects medium-sized and large arteries. A viral cause has been suspected but not confirmed in polymyalgia rheumatica and giant-cell arteritis. We report the case of a 81-year-old female who suffered from chronic active Epstein-Barr virus infection and developed giant cell temporal arteritis.

Comprehensive analysis of interacting proteins and genome-wide location studies of the Sas3-dependent NuA3 histone acetyltransferase complex

2014

Highlights • We characterise Sas3p and Gcn5p active HAT complexes in WT and deleted TAP-strains. • We confirm that Pdp3p interacts with NuA3, histones and chromatin regulators. • Pdp3p MS-analysis reveals its phosphorylation, ubiquitination and methylation. • Sas3p can substitute Gcn5p in acetylation of histone H3K14 but not of H3K9. • Genome-wide profiling of Sas3p supports its involvement in transcriptional elongation.

Lessons learned from Creation of Digitally Competent Educators SLP

2021

[Introduction] Mismatch of competences and socio-economical results of this issue is recognized as an important problem for higher education institutes (HEIs) in Europe. To cope with this issue HEIs need to create new more flexible and modular structures. In this context, a European HEIs are encouraged to create micro-credentials and short learning programmes (Futures et al., 2020). European Short Learning Programmes (E-SLPs) are one of these new and flexible structures suggested by an EU Project funded under Erasmus+ Programme, Key Action 3: Support for Policy Reform, Initiatives for Policy Innovation, "Forward Looking Cooperation Projects". SLPs have potential to respond to market needs a…

Analysing students’rating of the SLP Digitally Competent Educators

2021

This article uses student feedback to examine the perspective of participants in the short learning programme (SLP) pilot Digitally Competent Educators (DCE). This SLP was targeted at the continuous professional development and lifelong learning for educators at various levels and several education areas. Student feedback was collected in 2020 using anonymous surveys at the end of each course. This implies that respondents were those participants who completed the course. Feedback, used on further development of the SLP, focused on the content and implementation of the course modules. The SLP followed the design guidelines produced inside the E-SLP project and was based on the Digital Compe…

Role of volatile and contact pheromones in the mating behaviour of Bagrada hilaris (Heteroptera: Pentatomidae)

2008

Volatiles and contact pheromones involved in the mating behaviour of the Painted bug, Bagrada hilaris Burmeister (Het- eroptera: Pentatomidae), were investigated in behavioural and chemical experiments. Vertical open Y-shaped olfactometer bioassays showed that odour from males attract females but not males, while that from females did not attract either gender. Adult females were also attracted by hexane extracts of volatile compounds collected from males. In open arena bioassays, males displayed the characteristic steps of courtship behaviour in the presence of virgin females. Such courtship behaviour was displayed in the presence of females killed by freezing, but not in the presence of f…
