Cryopreservation of GABAergic neuronal precursors for cell-based therapy
Cryopreservation protocols are essential for stem cells storage in order to apply them in the clinic. Here we describe a new standardized cryopreservation protocol for GABAergic neural precursors derived from the medial glanglionic eminence (MGE), a promising source of GABAergic neuronal progenitors for cell therapy against interneuron-related pathologies. We used 10% Me2 SO as cryoprotectant and assessed the effects of cell culture amplification and cellular organization, as in toto explants, neurospheres, or individualized cells, on post-thaw cell viability and retrieval. We confirmed that in toto cryopreservation of MGE explants is an optimal preservation system to keep intact the interneuron precursor properties for cell transplantation, together with a high cell viability (>80%) and yield (>70%). Postthaw proliferation and self-renewal of the cryopreserved precursors were tested in vitro. In addition, their migration capacity, acquisition of mature neuronal morphology, and potency to differentiate into multiple interneuron subtypes were also confirmed in vivo after transplantation. The results show that the cryopreserved precursor features remained intact and were similar to those immediately transplanted after their dissection from the MGE. We hope this protocol will facilitate the generation of biobanks to obtain a permanent and reliable source of GABAergic precursors for clinical application in cell-based therapies against interneuronopathies.Ministerio de Economía y Competitividad 09-07746 y 12-36853Junta de Andalucía CTS- 256
Gut Microbiota of Great Spotted Cuckoo Nestlings is a Mixture of Those of Their Foster Magpie Siblings and of Cuckoo Adults
Diet and host genetic or evolutionary history are considered the two main factors
determining gut microbiota of animals, although studies are scarce in natural populations. The system
of great spotted cuckoos (Clamator glandarius) parasitizing magpies (Pica pica) is ideal to study both
effects since magpie adults feed cuckoo and magpie nestlings with the same diet and, consequently,
differences in gut microbiota of nestlings of these two species will mainly reflect the importance of
genetic components. Moreover, the diet of adults and of nestling cuckoos drastically differ from each
other and, thus, differences and similarities in their microbiotas would respectively reflect the effect
of environmental and genetic factors. We used next-generation sequencing technologies to analyze
the gut microbiota of cuckoo adults and nestlings and of magpie nestlings. The highest -diversity
estimates appeared in nestling cuckoos and the lowest in nestling magpies. Moreover, despite the
greatest differences in the microbiome composition of magpies and cuckoos of both ages, cuckoo
nestlings harbored a mixture of the Operational Taxonomic Units (OTUs) present in adult cuckoos
and nestling magpies. We identified the bacterial taxa responsible for such results. These results
suggest important phylogenetic components determining gut microbiome of nestlings, and that diet
might be responsible for similarities between gut microbiome of cuckoo and magpie nestlings that
allow cuckoos to digest food provided by magpie adults.This work was supported by the Ministerio de Ciencia, Innovacion y Universidades and European

Responsabilidad social: perspectiva del alumnado de Administración y Dirección de Empresas
[Resumen] En esta comunicación se recoge la perspectiva del alumnado perteneciente a primero del
grado de Administración y Dirección de Empresas de la Facultad de Economía y Empresa, en
la Universidade da Coruña durante el curso 2016-2017, en torno a la responsabilidad social.
Este trabajo está dividido en tres fases, la primera, la recogida de información cuantitativa
mediante un cuestionario estructurado, la segunda, el desarrollo de un trabajo cualitativo por
parte del alumnado y la última fase, exposición y reflexión oral del alumnado en torno a la
temática.
En la primera fase de este trabajo se analiza el grado de conocimiento del concepto de la
responsabilidad social; la identificación de las dimensiones de la responsabilidad social; la
principal finalidad que percibe el alumnado para llevar a cabo políticas de responsabilidad
social en las organizaciones; la clasificación de los sectores según su grado de implicación en materia de responsabilidad social (entre los que se encuadra la educación en comparación con otros sectores); la importancia de los requisitos para clasificar a las organizaciones como socialmente responsables; y los programas en los que desearía participar el alumnado una vez que finalicen sus estudios en la universidad
The microbiome of the uropygial secretion in hoopoes is shaped along the nesting phase
Microbial symbiont acquisition by hosts may determine the effectiveness of the mutualistic relationships. A mix of vertical and horizontal transmission may be advantageous for hosts by allowing plastic changes of microbial communities depending on environmental conditions. Plasticity is well known for gut microbiota but is poorly understood for other symbionts of wild animals. We here explore the importance of environmental conditions experienced by nestling hoopoes (Upupa epops) during the late nesting phase determining microbiota in their uropygial gland. In cross-fostering experiments of 8 days old nestlings, “sibling-sibling” and “mother-offspring” comparisons were used to explore whether the bacterial community naturally established in the uropygial gland of nestlings could change depending on experimental environmental conditions (i.e., new nest environment). We found that the final microbiome of nestlings was mainly explained by nest of origin. Moreover, cross-fostered nestlings were more similar to their siblings and mothers than to their stepsiblings and stepmothers. We also detected a significant effect of nest of rearing, suggesting that nestling hoopoes acquire most bacterial symbionts during the first days of life but that the microbiome is dynamic and can be modified along the nestling period depending on environmental conditions. Estimated effects of nest of rearing, but also most of those of nest of origin are associated to environmental characteristics of nests, which are extended phenotypes of parents. Thus, natural selection may favor the acquisition of appropriated microbial symbionts for particular environmental conditions found in nests.Support by funding was provided by Spanish Ministerio de Economía y Competitividad, European funds (FEDER) (CGL2013-48193-C3-1-P, CGL2013-48193-C3-2-P), and Junta de Andalucía (P09-RNM-4557).

Influence of the Type of Diet on the Incidence of Pathogenic Factors and Antibiotic Resistance in Enterococci Isolated from Faeces in Mice
A comparative study on potential risks was carried out in a collection of 50 enterococci
isolated from faeces of mice fed a standard or a high-fat diet enriched with extra virgin olive oil,
refined olive oil or butter, at the beginning, after six weeks and after twelve weeks of experiments.
Strains were biochemically assessed and genetically characterized. E. faecalis and E. casseliflavus were
the most frequently isolated species in any diet and time points. Apart from the fact of not having
isolated any strain from the virgin olive oil group during the last balance, we found statistically
significant differences (p < 0.05) among the diets in the percentage of antibiotic resistance and in
the presence of the enterococcal surface protein gene (esp), as well as a tendency (p < 0.1) for the
presence of the tyrosine decarboxylase gene (tdc) to increase over time in the group of isolates from
the standard diet. When the resistance of the strains to virgin or refined olive oil was studied, only the
group of enterococci from high fat diets showed a significantly higher percentage of resistance to
refined olive oil (p < 0.05), while both types of oil equally inhibited those isolated from the standard
diet (p > 0.05).This research was funded by University of Jaén (PP2009/13/03) (to IP) and Junta de Andalucía

Antibiotic-Producing Bacteria as a Possible Defence of Birds against Pathogenic Microorganisms
Resiliencia de la prensa local impresa frente a la sociedad digital
Printed editions of local press show significant resilience to the impact of the digital society within the Spanish market for printed publications. By number of mastheads and total circulation, these have proven to be the driving force of the Spanish press, as reflected on the number of deep-rooted centennial titles. Disaggregated analysis of their circulation data, using descriptive statistics applied to time series (2001-2018) data from OJD, strengthens the historic difference between the Northern and Southern regions of Spain, where the first one shows higher adaptability and a better fit with digital media consumption.; Las ediciones impresas de la prensa local presentan, en el mercado español de publicaciones periódicas en papel, cierta resiliencia al impacto de la sociedad digital. Por número de cabeceras y difusión total, constituyen el motor de la prensa española, donde gozan del arraigo que se refleja en su número de títulos centenarios. El análisis desagregado de su difusión, mediante estadística descriptiva aplicada a series temporales (2001-2018), con datos de OJD, indica una significativa diferencia entre el Norte y el Sur de España, donde el primero muestra más capacidad de adaptación e hibrida mejor con el consumo digital
