Übertragung von Verhaltensweisen durch Transplantation von Anlagen neuroanatomischer Strukturen bei Amphibienlarven
2010
By replacing parts of the neural plate (prospective medulla oblongata) of Triturus vulgaris by neural ectoderm of Xenopus laevis larval chimaeras were obtained, which showed donorlike rhythmical movements of distinct parts of the visceral musculature according to the place of implantation. Especially the branchial region with its external gills showed rhythmical movements and is the special object of this investigation.

La evolución en los tribunales: aplicaciones forenses de las filogenias moleculares
2013
En las dos últimas décadas se ha generalizado el uso de pruebas genéticas en los tribunales, permitiendo la identificación de criminales a partir de restos biológicos, la determinación de paternidades o la identificación de cadáveres. Menos conocidas son las periciales basadas en el uso de filogenias moleculares. En ellas se estudia la ancestralidad común de organismos, normalmente virus o bacterias, para establecer su asociación a una fuente de infección. Desde el caso del dentista de Florida, que infectó con el VIH a varios de sus pacientes, hasta el más próximo del anestesista Juan Maeso, que transmitió el VHC a cerca de 300 pacientes, la teoría evolutiva tiene un papel esencial en estas…
Rapid vascularization of starchâ poly(caprolactone) in vivo by outgrowth endothelial cells in co-culture with primary osteoblasts
2011
The successful integration of in vitro-generated tissues is dependent on adequate vascularization in vivo. Human outgrowth endothelial cells (OECs) isolated from the mononuclear cell fraction of peripheral blood represent a potent population of circulating endothelial progenitors that could provide a cell source for rapid anastomosis and scaffold vascularization. Our previous work with these cells in co-culture with primary human osteoblasts has demonstrated their potential to form perfused vascular structures within a starch–poly(caprolactone) biomaterial in vivo. In the present study, we demonstrate the ability of OECs to form perfused vascular structures as early as 48 h following subcut…
Key Concept: Criticality
2016
In English language education, the word 'critical' can be used in different ways, qualifying different phenomena. Thus, the development of 'critical thinking' is a goal in some ELT classrooms or teacher education programmes; there is also 'critical pedagogy', which seeks empowerment and social transformation; and 'critical perspectives' can be taken towards the enterprise of ELT itself. Here, we will try to show how these apparently different forms of criticality are linked together.
Innovación pedagógica en educación física: una propuesta de orientación basada en AICLE
2015
In today's society, languages, especially English language, have acquired great relevance due to the unstoppable process of globalization. Schools must adapt to these kind of social demands. Because of this fact, methodologies such as Content Led Integrated Language Learning (CLIL) are being used more and more often. Here a didactic unit for working orienteering by using CLIL is proposed in order to demonstrate that Physical Education (PE) provides a suitable context in which the use of the language is significant and relevant. Through this proposal, it is shown the great potential of PE to enhance language learning.
Uses of Code-Switching in Four-Year-Old Monolingual Children's Second Language Acquisition
2013
Code-Switching is a phenomenon in which ¿speakers rely on juxtaposition of grammatically distinct subsystems to generate conversational inferences¿ according to Gumperz (1982:97). The broad use of code-switching in diverse contexts and with at least two languages in contact has made this linguistic device be one of the most studied behavioural features of bilinguals¿ speech (Gregori and Alcantud.2011). Additionally, code-switching, seems to have an important communicative function, that is why it is a very interesting aspect of sociolinguistics to be researched.Nowadays, the development of educational provision is reaching more and more social strata. This fact, together with a wider use of…
David Lasagabaster, Aintzane Doiz and Juan Manuel Sierra, eds. 2014. Motivation and Foreign Language Learning. From Theory to Practice. 190 pp. Amste…
2015
The present volume, edited by Lasagabaster, Doiz and Sierra, brings together different perspectives on the interrelation between motivation and foreign language learning. Following the editors' introduction, which carefully summarizes the main ideas explored in each chapter¿hence my decision not to organize this review in the same way, but rather to focus on a general aspect that has the potential to encompass all of them¿the volume is divided into two parts, each of four chapters. Whereas the first part is theoretically oriented, the second comprises individual studies. The volume ends with the editors' epilogue, in which an attempt is made to present a unified reading of the contributions
Response to: 'IL-23 expression and activation of autophagy in synovium and PBMCs of HLA-B27 positive patients with ankylosing spondylitis' by Neerinc…
2014
We read with interest the study by Neerinckx et al 1 addressing the expression of interleukin (IL)-23p19 and of autophagy genes in the synovium and in the peripheral blood mononuclear cells of patients with ankylosing spondylitis (AS). Differently from our observation in the gut,2 the authors failed to demonstrate any significant increase by RT-PCR in the expression of synovium autophagy-related genes (ATG16L1, IRGM, MAP1LC3A, ATG5, HSPA8 and HSP90AA1) together with no significant overexpression of IL-23p19 compared with disease and healthy controls. We have previously demonstrated by immunohistochemistry that in the …
Antibiotic Resistance of Gram Negatives isolates from loggerhead sea turtles (Caretta caretta) in the central Mediterranean Sea
2009
Previous studies on fish and marine mammals support the hypothesis that marine species harbor antibiotic resistance and therefore may serve as reservoirs for anti biotic-resistance genetic determinants. The aim of this study was to assess the resistance to antimicrobial agents of Gram negative strains isolated from loggerhead sea turtles (Caretta caretta). Oral and cloacal swabs from 19 live-stranded loggerhead sea turtles, with hooks fixed into the gut, were analyzed. The antimicrobial resistance of the isolates to 31 antibiotics was assessed using the disk-diffusion method. Conventional biochemical tests identified Citrobacter spp., Proteus spp., Enterobacter spp., Escherichia spp., Provi…
