ABSTRACT During gastrulation, embryonic cells become specified into distinct germ layers. In mouse, this continues throughout somitogenesis from a population of bipotent stem cells called neuromesodermal progenitors (NMps). However, the degree of self-renewal associated with NMps in the fast-developing zebrafish embryo is unclear. Using a genetic clone-tracing method, we labelled early embryonic progenitors and found a strong clonal similarity between spinal cord and mesoderm tissues. We followed individual cell lineages using light-sheet imaging, revealing a common neuromesodermal lineage contribution to a subset of spinal cord tissue across the anterior-posterior body axis. An initial pop…
« Nez et langues électroniques » : bilan et perspectives pour les huiles alimentaires
2003
Le « Nez electronique », et plus recemment la « Langue electronique » ont ete fort mediatises durant la derniere decennie. Aussi est-il necessaire, avec le recul, de faire le point sur les benefices que ces technologies peuvent apporter dans le domaine des produits alimentaires, et en particulier pour huiles vegetales. On trouve une litterature relativement abondante dans ce domaine, mais les applications qui ont reussi a franchir le cap de l’utilisation industrielle sont extremement restreintes. S’agit-il d’une frilosite des industriels pour des investissements de controle-qualite ou d’un manque de fiabilite des resultats de laboratoire ? Pourtant, la demande en outils rapides de controle-…
Viral entry, lipid rafts and caveosomes.
2005
Lipid rafts and caveolae are detergent-insoluble plasma membrane microdomains, involved in cellular endocytic processes and signalling. Several viruses, including a human pathogen, echovirus 1, and an extensively studied simian virus 40 utilize these domains for internalization into the host cells. Interaction of viruses with receptors on the cell surface triggers specific conformational changes of the virus particle and can give rise to signalling events, which determine the mechanisms of virus entry. After internalization via cell surface lipid rafts or caveolae, virus-containing vesicles can fuse with caveosomes, pre-existing cytoplasmic organelles, or dock on other intracellular organel…
Physicochemical properties, sugar profile, and non-starch polysaccharides characterization of old wheat malt landraces
2021
Abstract Craft beers produced by small breweries are becoming increasingly popular worldwide due to their unique composition, taste, and flavour. Wheat malt is a traditional brewing raw material with great potential to improve beer properties such as mouthfeel, foam, haze, and flavour. In this study, the malting quality of eight wheat varieties (four common and four durum) was evaluated to explore the feasibility of producing 100 % wheat malt beer from old landraces. The physicochemical characteristics such as friability, Kolbach index, viscosity, and colour, of the wheat malts indicated a better degree of modification in the common wheat varieties when compared to that of the durum wheat v…
Graduating Physiotherapy Students’ Conceptions of their own Competence
2017
A competence-oriented approach has recently emerged in higher education and thus far, not much attention has been paid to how “competence” itself is understood in education. The purpose of this study was to examine how graduating physiotherapy students perceive their competence at the end of their studies. The data comprised interviews with 33 graduating physiotherapy students. The data were analysed with the phenomenographic approach. The findings indicated that graduating students had different and wide-ranging conceptions of what competence in physiotherapy entails and what their own competence covers. The descriptive categories – mastering core skills, understanding the theoretical basi…
Patients’ conceptions of preoperative physiotherapy education before hip arthroplasty
2015
In Finland, over 7500 hip arthroplasties are performed annually. While the mean age of the patients has increased, the length of hospital stay has decreased, and this presents challenges for patient education. The aim of this study was to explore patients’ conceptions of preoperative physiotherapy education. This qualitative study included 10 hip arthroplasty patients. Data were collected using individual interviews at home before collecting preoperative information, and at the hospital after the operation. The interviews were tape-recorded and analysed using the phenomenographic method. Four hierarchically constructed categories of preoperative physiotherapy education were identified: read…
Physiotherapists’ conceptions of movement awareness– A phenomenographic study
2021
The phenomenon of movement awareness requires more attention to make it explicit in physiotherapy. The aim of this study was to explore the variation in physiotherapists’ conceptions of movement quality, focusing on movement awareness. The informants were 15 physiotherapists from a variety of physiotherapy fields. We collected data through two group interviews and used the phenomenographic method to analyze them. Four themes emerged from the data: 1) Being in contact with one’s own moving body; 2) Increased awareness of movement experiences; 3) Interrelationship between physiotherapist and patient; and 4) Better understanding of movement awareness. These themes varied by four descriptive ca…
Franco’s dictatorship in recent school textbooks: A critical review
2018
Este artículo analiza de forma panorámica el tratamiento de la dictadura franquista en los manuales escolares españoles de educación primaria, secundaria y bachillerato de los últimos veinte años. Se parte de la siguiente premisa: el tratamiento educativo de un pasado conflictivo y “candente” como el del franquismo debe preocupar de forma especial a la comunidad de investigadores y profesores de Historia, en tanto en cuanto tiene profundas repercusiones potenciales en la construcción de las identidades sociopolíticas de las nuevas generaciones. En este sentido, el artículo, aunque no niega los avances producidos, focaliza su atención en las carencias metodológicas, epistemológicas e interpr…
“Minding the gap” in the research on human trafficking for sexual purposes
2017
Since the signature of the United Nations Trafficking Protocol in December 2000 that human trafficking has been labelled as a transnational, complex criminal phenomenon. However, despite the implementation of international soft law instruments to tackle the phenomenon, human trafficking is constantly evolving by the frequent changes of strategies, routes, types of exploitation and methodologies applied by the criminal networks. This flexibility of the phenomenon does not only difficult the implementation of effective tackling measures, but it also demonstrates to be an obstacle to produce accurate information on the subject (Cusick et al, 2009). Furthermore, due to the hidden nature of the …
Una segregazione paradossale e multi-scalare: il caso del quartiere ZEN di Palermo
2016
L’articolo affronta la questione della segregazione nel quartiere ZEN di Palermo (Sicilia). L’impianto teorico dialoga con la letteratura anglosassone, ma ne prende le distanze nel tentativo di individuare alcune specificità locali del caso. L’obiettivo è duplice: intanto indentificare alcuni “movimenti geostorici” che hanno caratterizzato il quartiere, collegando a ciascuno di questi una fase del processo segregativo; inoltre, rappresentare la segregazione del quartiere in forma cartografica, mediante l’uso di alcuni ideogrammi e mappe mentali. This article deals with the issue of segregation in the ZEN district of Palermo, Sicily. The theoretical framework is built around Anglo-Saxon refe…
