The Concept of “Sala de Fabrica”: On-Site Museums to Raise Awareness of Cultural Heritage After a Restoration Project
A conservation process usually generates new knowledge and an enormous amount of documentation during the inception and implementation of the project: the information collected from archives and other institutions; the information provided by the preliminary studies carried out prior to the intervention; the data provided in the field during the works and at the end of the process; and the final set of documentation delivered to the institution responsible for the maintenance and management of the monument. The challenge for conservation professionals and cultural heritage managers throughout this process once the works are over is to achieve and transmit this information to the public and specialists in order to raise awareness for better conservation of our built heritage. During the last few years, one of the actions that the Caja Madrid Foundation has activated with its restoration projects has been the opening of permanent on site museums or “Salas de Fábrica”, a place on site to understand the restoration works, to exhibit the remains that have being retrieved during the project and to permit the public to better understand the historical and artistic values of architectural and archaeological heritage as well as the importance of preserving our cultural legacy for the future

Analizando la alfabetización en salud sobre COVID-19 del profesorado en formación inicial
This study analyses the level of health literacy exhibited by 44 Primary Education pre-service teachers (PST) after participating in an argument-driven inquiry around the socio-scientific dilemma of vaccination on COVID-19 and the subsequent elaboration of educational transpositions for its treatment in the science classroom. Employing the ADI rubric (argument-driven inquiry), which evaluates the understanding of the content and the scientific context associated with these educational approaches, we value the degree of acquisition of each one of them. The scores obtained in the rubric (high, medium and low) and qualitative analysis of the proposals designed are linked to the different hierarchy levels of health literacy (functional, communicative and critical) to give an idea of the degree of acquisition. The results show a medium-high grade in the functional and communicative levels, and a low grade in the critical level, the latter associated with the development of community actions in the educational field, revealing the need to deepen in training actions that involve these teachers in the social role of science.

Este estudio analiza el nivel de alfabetización en salud que muestran 44 maestros y maestras en formación inicial del grado de Educación Primaria (PFI), tras participar en una actividad de indagación dirigida por la argumentación en torno al dilema socio-científico de la vacunación sobre COVID-19 y la posterior elaboración de transposiciones didácticas que estos futuros docentes diseñaron como sus propuestas de enseñanza para el tratamiento en el aula de ciencias. Empleando la rúbrica IDA (indagación dirigida por la argumentación), que evalúa la comprensión del contenido y el contexto científicos asociados a estos enfoques didácticos, valoramos el grado de adquisición de cada uno de ellos alcanzado por estos futuros docentes. Las puntuaciones obtenidas en la rúbrica (alta, media y baja) y el análisis cualitativo de las propuestas didácticas que diseñaron se vinculan con los diferentes niveles de jerarquía de la alfabetización en salud (funcional, comunicativo y crítico) para dar una idea del grado de adquisición. Los resultados muestran un grado medio-alto en los niveles funcional y comunicativo, y un grado bajo en el nivel crítico, asociado este último al desarrollo de acciones comunitarias en el ámbito educativo, revelando la necesidad de profundizar en acciones formativas que involucren a este profesorado en la vertiente más social de la ciencia.

Sgs1’s roles in DNA end resection, HJ dissolution, and crossover suppression require a two-step SUMO regulation dependent on Smc5/6
The RecQ helicase Sgs1 plays critical roles during DNA repair by homologous recombination, fromend resection to
Holliday junction (HJ) dissolution. Sgs1 has both pro- and anti-recombinogenic roles, and therefore its activity must
be tightly regulated. However, the controls involved in recruitment and activation of Sgs1 at damaged sites are
unknown. Here we show a two-step role for Smc5/6 in recruiting and activating Sgs1 through SUMOylation. First,
auto-SUMOylation of Smc5/6 subunits leads to recruitment of Sgs1 as part of the STR (Sgs1–Top3–Rmi1) complex,
mediated by two SUMO-interacting motifs (SIMs) on Sgs1 that specifically recognize SUMOylated Smc5/6. Second,
Smc5/6-dependent SUMOylation of Sgs1 and Top3 is required for the efficient function of STR. Sgs1 mutants impaired
in recognition of SUMOylated Smc5/6 (sgs1-SIMΔ) or SUMO-dead alleles (sgs1-KR) exhibit unprocessed HJs
at damaged replication forks, increased crossover frequencies during double-strand break repair, and severe impairment
in DNA end resection. Smc5/6 is a key regulator of Sgs1’s recombination functions.We thank the Aragon laboratory for discussions and critical reading of the manuscript.We thank the Clinical Sciences Centre Proteomics Facility (P.

Accuracy and precision of automated subjective refraction in young hyperopes under cycloplegia
Purpose: To assess the agreement between the Eye Refract, an instrument to perform subjective automated refraction, and the traditional subjective refraction, as the gold standard, in young hyperopes under noncycloplegic and cycloplegic conditions.
Methods: A cross-section and randomized study was carried out, involving 42 participants (18.2 ± 7.7 years, range 6 to 31 years). Only one eye was chosen for the analysis, randomly. An optometrist conducted the refraction with the Eye Refract, while another different optometrist conducted the traditional subjective refraction. Spherical equivalent (M), cylindrical components (J0 and J45), and corrected distance visual acuity (CDVA) were compared between both refraction methods under noncycloplegic and cycloplegic conditions. A Bland-Altman analysis was performed to assess the agreement (accuracy and precision) between both refraction methods.
Results: Without cycloplegia, the Eye Refract showed significantly lower values of hyperopia than the traditional subjective refraction (p < 0.009), the mean difference (accuracy) and its 95% limits of agreement (precision) being -0.31 (+0.85, -1.47) D. Conversely, there were no statistical differences between both refraction methods under cycloplegic conditions (p ≥ 0.05). Regarding J0 and J45, both refraction methods manifested no significant differences between them under noncycloplegic and cycloplegic conditions (p ≥ 0.05). Finally, the Eye Refract significantly improved CDVA (0.04 ± 0.01 logMAR) compared with the traditional subjective refraction without cycloplegia (p = 0.01).
Conclusions: The Eye Refract is presented as a useful instrument to determine the refractive error in young hyperopes, the use of cycloplegia being necessary to obtain accurate and precise spherical refraction.Depto. de Optometría y VisiónFac. de Óptica y OptometríaTRUEinpres
Data on natural radionuclide's activity concentration of cement-based materials
Cement based materials may contain varying levels of radionuclides, mainly 226Ra (from the 238U series), 232Th and 40K, which are used to determine the Activity Concentration Index ("ACI"). According to the European directive Euratom 2013/59 in these materials, the “ACI” must be < 1 to be suitable for their use in construction. In this paper, data on the activity concentration of natural radionuclides in cement-based materials (i.e. cements, additions, pigments and aggregates) as well as their chemical composition are presented. Radioactivity measurements have been determined by using gamma spectroscopy the chemical compositions have been determined by X-Ray Fluorescence. Data for cements measured shown that white cements present a lower concentration of activity than conventional CEM I. In addition, the CAC (Calcium aluminate cements) present high activity concentration in the 232Th series. Regarding additions, FA (Fly Ash) are those that present the highest concentration of activity in the 238U and 232Th series, while olive biomass ashes are those supplementary cementitious materials that show the highest concentration of activity for 40K. Some pigments used in mortar and concrete technology were also characterized. Granitic and volcanic rocks, potentially used as aggregates present much higher activity concentration than the siliceous aggregate.This study was funded by the Spanish Ministry of the Economy, Industry and Competitiveness under project BIA2016-77252-P.

Recommendations by the Spanish Society of Epidemiology and Oral Public Health (SESPO) for the healthcare adaptation of public health dental clinics in Spain during the COVID-19 pandemic
In March 2020, the World Health Organization (WHO) declared the COVID-19 pandemic and, a few days later, the Spanish Government declared a State of Emergency and the population lockdown. This crisis situation crisis forced deep changes in health care. A
Delivery of Health Care by Spanish Dental Hygienists in Private and Public Dental Services during the COVID-19 De-Escalation Phase (June 2020): A Cross-Sectional Study
Background: The first wave of the COVID-19 pandemic in Spain posed a major challenge for Spanish dental professionals. The objective of this work is to describe the dental hygienists’ work status and employment patterns during the de-escalation phase in order to analyse the standards of knowledge, compliance with official recommendations, and dental activities both in the public health service and in the private sector. Material and Methods: A cross-sectional questionnaire was answered by Spanish dental hygienists via WhatsApp, Facebook, and Instagram. The questionnaire was piloted before it was distributed and carried out during June 2020. Results: Here, 517 dental hygienists were surveyed, of which 86.2% followed the official recommendations to avoid contagion and 63.8% agreed with the gradual return to work by limiting the use of aerosols. Private dental hygienists identified more with returning to work without restrictions (14.5%) versus those working for the public service (1.2%) (p < 0.005). Conclusions: Dental hygienists’ return to work has involved different strategies, aimed at controlling infection and guaranteeing the safety of patients and the rest of the dental team. The availability of personal protective equipment, the adaptation of clinical infrastructure, and patient care management have differed between professionals working in the private and public sectors
