Algunas consideraciones sobre la crisis del modelo territorial en España”

Si bien el proceso de descentralización llevado a cabo en la Constitución española fue positivo en muchos aspectos, no sirvió para resolver los problemas inherentes al nacionalismo vasco y catalán. Ello contrasta con el importantísimo nivel de descentralización alcanzado en nuestro país y que no tiene parangón con los países de nuestro entorno, ni siquiera con algunos modelos de Estado federal. Para un mejor entendimiento de nuestro modelo territorial, se hace necesario analizar las distintas etapas de consolidación del Estado autonómico. Entendiendo así un primer periodo entre 1981 y 1992 en los que se firman los primeros Pactos Autonómicos. Se hace un estudio de lo que supusieron estos primeros Pactos en la conformación de lo que después sería nuestro modelo territorial que, aunque nace de la Constitución española, luego fue conformándose de manera paralela a ésta. Lo anterior es relevante analizar para una mejor comprensión de la problemática existente actualmente con el independentismo catalán y vasco. Los Pactos de 1992 propiciaron la conformación del Estado autonómico, si bien ello no contentó a las autonomías que accedieron a la misma por la vía del art. 151 de la Constitución. La etapa final, desde el año 2006 en adelante, marca lo que denominamos “segunda descentralización” y que se inicia con el Estatuto Catalán de 2006.Fijada la configuración del Estado autonómico, se analiza los problemas que deriva de los Pactos/acuerdos/desarrollos normativos del Título VIII de la Constitución Española. Como aspecto relevante se analiza el protagonismo de Andalucía en el desarrollo del Estado autonómico

FSC-Q: a CryoEM map-to-atomic model quality validation based on the local Fourier shell correlation

In recent years, advances in cryoEM have dramatically increased the resolution of reconstructions and, with it, the number of solved atomic models. It is widely accepted that the quality of cryoEM maps varies locally; therefore, the evaluation of the maps-derived structural models must be done locally as well. In this article, a method for the local analysis of the map-to-model fit is presented. The algorithm uses a comparison of two local resolution maps. The first is the local FSC (Fourier shell correlation) between the full map and the model, while the second is calculated between the half maps normally used in typical single particle analysis workflows. We call the quality measure “FSC-Q”, and it is a quantitative estimation of how much of the model is supported by the signal content of the map. Furthermore, we show that FSC-Q may be helpful to detect overfitting. It can be used to complement other methods, such as the Q-score method that estimates the resolvability of atomsWe thank Prof. David Veesler for providing us the half maps of the spike glycoprotein of SARS-CoV-2.

Monitoring workload and performance response to taekwondo training

This study compared the association between Foster’s and Banister’s TRIMP methods for quantifying internal training load and training stimuli responses. Methods: A group of twenty-two Taekwondo competitors were divided by gender and level of expertise. The athletes practiced three different types of exercises to develop the following skills: a) speed, b) power, and c) aerobic power. Results: A significant correlation was obtained between the Foster’s and Banister’s TRIMP methods for developing aerobic capacity (r = 0.60, p = 0.004) and power (r = 0.52, p = 0.014). No significant correlation was suggested between training methods and speed training (r = 0.20, p = 0.377). Conclusion: Lactate and heart rate responses to different types of exercises suggested the need for aerobic and anaerobic-based training sessions. The use of rating of perceived exertion scale-based measurements to monitor workload is recommended for Taekwondo competitors

Occurrence of antibiotics in Lettuce (Lactuca sativa L.) and Radish (Raphanus sativus L.) following organic soil fertilisation under plot-scale conditions: Crop and human health implications

Recent studies have demonstrated the crop uptake of antibiotics (ABs) from soils treated with AB-carrying fertilisers. However, there is a lack of plot-scale studies linking their effects at the agronomic and metabolomic/transcriptomic level to their impact on human health. This paper assesses the plant uptake of 23 ABs following two productive cycles of lettuce and radish cropped with sewage sludge, pig slurry, the organic fraction of municipal solid waste, or chemical fertilisation under plot-scale conditions (32 plots spanning 3-10 m2 each). AB uptake by plants depended on both the vegetable and the AB class and was higher in radish than in lettuce edible parts. Levels ranged from undetectable to up to 76 ng/g (fresh weight). Repetitive organic fertilisation resulted in an increase in the concentration of ABs in lettuce leaves, but not in radish roots. Significant metabolomic and transcriptomic changes were observed following soil fertilisation. Nevertheless, a human health risk assessment indicates that the occurrence of ABs in lettuce or radish edible parts does not pose any risk. To our knowledge, this is the first holistic plot-scale study demonstrating that the use of organic fertilisers containing ABs is safe for crop security and human health.The authors gratefully acknowledge the financial support of the Spanish Ministry of Science and Innovation through projects AGL2017- 89518-R and RTI2018-096175-B-I00.

Current Advances Research in Nutraceutical Compounds of Legumes, Pseudocereals and Cereals

The increase of the Western-type diet and life-style, with high content of highly processed fats, salt and sugar, as well as sedentary life, is directly linked to an increasing incidence of chronic diseases such as diabetes and obesity, cancer, cardiovascular diseases or stroke, and inflammatory-related diseases, which are a great challenge in global health and are usually associated with negative effects of globalization: rapid urbanization, diet and increased sedentary life worldwide. This has brought new interest and increased research into plant-based diets. In this context, the implementation in the diet of legumes, cereals and pseudo-cereals, due to their nutraceutical properties, which is interesting as well as advisable. These foods, in addition of having a high nutritional value themselves, have synergistic properties as part of a balanced diet. For example, most legumes are rich in lysine which is scarce in cereals, and these are rich in sulphur amino acids, such as methionine, while these amino acids are scarce in legumes and are of great importance for the central nervous system development. These foods or part of a food, due to their qualities, and that they provide health benefits can be classified as nutraceuticals. In addition, due to their health benefits beyond nutritional properties, can be classified as functional foods, promoting prevention and treatment for the above mentioned diseases, among others. This double function is due mainly to the proteins and the presence of various secondary metabolites and bioactive compounds in these foods of plant (grain and seed) origin. Last discovered knowledge and research features will be described in the present book chapter

Continuous flexibility analysis of SARS-CoV-2 spike prefusion structures

Using a new consensus-based image-processing approach together with principal component analysis, the flexibility and conformational dynamics of the SARS-CoV-2 spike in the prefusion state have been analysed. These studies revealed concerted motions involving the receptor-binding domain (RBD), N-terminal domain, and subdomains 1 and 2 around the previously characterized 1-RBD-up state, which have been modeled as elastic deformations. It is shown that in this data set there are not well defined, stable spike conformations, but virtually a continuum of states. An ensemble map was obtained with minimum bias, from which the extremes of the change along the direction of maximal variance were modeled by flexible fitting. The results provide a warning of the potential image-processing classification instability of these complicated data sets, which has a direct impact on the interpretability of the results.The authors would like to acknowledge financial support from CSIC (PIE/COVID-19 No. 202020E079), the Comunidad de Madrid through grant CAM (S2017/BMD-3817), the Spanish Ministry of Science and Innovation through projects SEV 2017-0712, FPU-2015/264 and PID2019-104757RB-I00/AEI/ FEDER, the Instituto de Salud Carlos III [PT17/0009/0010 (ISCIII-SGEFI/ERDF)], and the European Union and Horizon 2020 through grants INSTRUCT–ULTRA (INFRADEV-03-2016-2017, Proposal 731005), EOSC Life (INFRAEOSC-04-2018, Proposal 824087), HighResCells (ERC-2018-SyG, Proposal 810057), IMpaCT (WIDESPREAD- 03-2018, Proposal 857203), CORBEL (INFRADEV-1-2014-1, Proposal 654248) and EOSC–Synergy (EINFRA-EOSC-5, Proposal 857647).

Beyond the consultation room : Proposals to approach health promotion in primary care according to health-care users, key community informants and primary care centre workers

Primary health care () is the ideal setting to provide integrated services centred on the person and to implement health promotion () activities. To identify proposals to approach in the context of primary care according to health-care users aged 45-75 years, key community informants and primary care centre () workers. Descriptive-interpretive qualitative research with 276 participants from 14 of seven Spanish regions. A theoretical sampling was used for selection. A total of 25 discussion groups, two triangular groups and 30 semi-structured interviews were carried out. A thematic interpretive contents analysis was carried out. Participants consider that is not solely a matter for the health sector and they emphasize intersectoral collaboration. They believe that it is important to strengthen community initiatives and to create a healthy social environment that encourages greater responsibility and participation of health-care users in decisions regarding their own health and better management of public services and resources. , care in the community and demedicalization should be priorities for . Participants propose organizational changes in the to improve . workers are aware that falls within the scope of their responsibilities and propose to increase their training, motivation, competences and knowledge of the social environment. Informants emphasize that should be person-centred approach and empathic communication. activities should be appealing, ludic and of proven effectiveness. According to a socio-ecological and intersectoral model, services must get actively involved in together with community and through outreach interventions

The structural role of SARS-CoV-2 genetic background in the emergence and success of spike mutations: The case of the spike A222V mutation

The S:A222V point mutation, within the G clade, was characteristic of the 20E (EU1) SARS-CoV-2 variant identified in Spain in early summer 2020. This mutation has since reappeared in the Delta subvariant AY.4.2, raising questions about its specific effect on viral infection. We report combined serological, functional, structural and computational studies characterizing the impact of this mutation. Our results reveal that S:A222V promotes an increased RBD opening and slightly increases ACE2 binding as compared to the parent S:D614G clade. Finally, S:A222V does not reduce sera neutralization capacity, suggesting it does not affect vaccine effectiveness

The Molecular Control of Calcitonin Receptor Signaling

The calcitonin receptor (CTR) is a class B G protein-coupled receptor (GPCR) that responds to the peptide hormone calcitonin (CT). CTs are clinically approved for the treatment of bone diseases. We previously reported a 4.1 Å structure of the activated CTR bound to salmon CT (sCT) and heterotrimeric Gs protein by cryo-electron microscopy (Liang, Y.-L., et al. Phase-plate cryo- EM structure of a class B GPCR-G protein complex. Nature 2017, 546, 118–123). In the current study, we have reprocessed the electron micrographs to yield a 3.3 Å map of the complex. This has allowed us to model extracellular loops (ECLs) 2 and 3, and the peptide N-terminus that previously could not be resolved. We have also performed alanine scanning mutagenesis of ECL1 and the upper segment of transmembrane helix 1 (TM1) and its extension into the receptor extracellular domain (TM1 stalk), with effects on peptide binding and function assessed by cAMP accumulation and ERK1/2 phosphorylation. These data were combined with previously published alanine scanning mutagenesis of ECL2 and ECL3 and the new structural information to provide a comprehensive 3D map of the molecular surface of the CTR that controls binding and signaling of distinct CT and related peptides. The work highlights distinctions in how different, related, class B receptors may be activated. The new mutational data on the TM1 stalk and ECL1 have also provided critical insights into the divergent control of cAMP versus pERK signaling and, collectively with previous mutagenesis data, offer evidence that the conformations linked to these different signaling pathways are, in many ways, mutually exclusive. This study furthers our understanding of the complex nature of signaling elicited by GPCRs and, in particular, that of the therapeutically important class B subfamily

The future of integrated structural biology

Instruct-ERIC, "the European Research Infrastructure Consortium for Structural biology research," is a pan-European distributed research infrastructure making high-end technologies and methods in structural biology available to users. Here, we describe the current state-of-the-art of integrated structural biology and discuss potential future scientific developments as an impulse for the scientific community, many of which are located in Europe and are associated with Instruct. We reflect on where to focus scientific and technological initiatives within the distributed Instruct research infrastructure. This review does not intend to make recommendations on funding requirements or initiatives directly, neither at the national nor the European level. However, it addresses future challenges and opportunities for the field, and foresees the need for a stronger coordination within the European and international research field of integrated structural biology to be able to respond timely to thematic topics that are often prioritized by calls for funding addressing societal needs
