Performance study of graphene oxide as an antierosion coating for ornamental and heritage dolostone

9 figures, 2 tables.-- Supplementary information available.Concern for the perpetuation of stone monuments is deeply ingrained in humans; however, despite the attempts made in this field, there is still a great deal of effort needed to bring about advancements in the conservation of ornamental stone. Erosive agents, such as rain, extreme temperatures, and chemical and biological agents, threaten our stone heritage and gradually wear away buildings, sculptures, and other monuments found all around the world. Limestone and dolostone have been widely used throughout history, given their ease of extraction and workability. Nevertheless, these properties make them particularly vulnerable to the aforementioned erosive agents, for which the main solution at present is costly and time-consuming restoration. Given the scarcity of effective and durable agents to prevent the deterioration of ornamental and heritage stones, and as graphene oxide (GO) has recently shown impressive effectiveness for this task, this work will further explore the viability of GO as a protective coating for monumental dolostone. For this purpose, GO is sprayed over dolostone surfaces by water dispersion with no adjuvants. The coating performance is assessed in terms of thermal stress, optical inspection (structured light 3D scanner), colorimetry, leachate analysis, and electron microscopy. The main results show that spray-coated GO over stone surfaces creates a highly protective and durable barrier without altering their aesthetic qualities.This research received funding from the University of León (ULE-PoC 2018) and Fundación General de la ULE y de la Empresa (FGULEM) under projects 2019/00149/001 and 2020. This research was also funded through an awarded MICINN project (PID2020-120439RA-I00). The authors are also thankful to the “Applied innovation against climate change and other aggressions on stone monuments (PRESERVARTE)” project of the Regional Ministry of Culture and Tourism of Castilla y León, which will be used to complement this research in the future.Peer reviewe

Primary respiratory disease in patients with systemic lupus erythematosus: data from the Spanish rheumatology society lupus registry (RELESSER) cohort

Background The purpose of this study was to assess the prevalence, associated factors, and impact on mortality of primary respiratory disease in a large systemic lupus erythematosus (SLE) retrospective cohort. Methods All adult patients in the RELESSER-TRANS (Registry of Systemic Lupus Erythematosus Patients of the Spanish Society of Rheumatology [SER], cross-sectional phase) registry were retrospectively investigated for the presence of primary pleuropulmonary manifestations. Results In total 3215 patients were included. At least one pleuropulmonary manifestation was present in 31% of patients. The most common manifestation was pleural disease (21%), followed by lupus pneumonitis (3.6%), pulmonary thromboembolism (2.9%), primary pulmonary hypertension (2.4%), diffuse interstitial lung disease (2%), alveolar hemorrhage (0.8%), and shrinking lung syndrome (0.8%). In the multivariable analysis, the variables associated with the development of pleuropulmonary manifestation were older age at disease onset (odds ratio (OR) 1.03, 95% confidence interval (CI) 1.02-1.04), higher SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) scores (OR 1.03, 95% CI 1.00-1.07), the presence of Raynaud's phenomenon (OR 1.41, 95% CI 1.09-1.84), secondary antiphospholipid syndrome (OR 2.20, 95% CI 1.63-2.97), and the previous or concomitant occurrence of severe lupus nephritis, (OR 1.48, 95% CI 1.12-1.95) neuropsychiatric manifestations (OR 1.49, 95% CI 1.11-2.02), non-ischemic cardiac disease (OR 2.91, 95% CI 1.90-4.15), vasculitis (OR 1.81, 95% CI 1.25-2.62), hematological manifestations (OR 1.31, 95% CI 1.00-1.71), and gastrointestinal manifestations, excluding hepatitis (OR 2.05, 95% CI 1.14-3.66). Anti-RNP positivity had a clear tendency to significance (OR 1.32, 95% CI 1.00-1.75; P = 0.054). The development of pleuropulmonary manifestations independently contributes to a diminished survival (hazard ratio of 3.13). However, not all complications will influence the prognosis in the same way. Whereas the occurrence of pleural disease or pulmonary thromboembolism has a minimal impact on the survival of these patients, the remaining manifestations have a major impact on mortality. Conclusion Except for pleural disease, the remaining respiratory manifestations are very uncommon in SLE (<4%). Pleuropulmonary manifestations independently contributed to a decreased survival in these patients

Responsible heritage protection actions

2 figures,1 table.-- Conference paper presented at the EURECA-PRO Conference - 2022 , held in León (Spain) from October 19 to October 21, 2022.-- Editorial policy for use: https://www.springernature.com/gp/open-research/policies/accepted-manuscript-termsIn recent decades, interest in maintaining and conserving cultural assets has grown and there has been greater investment in the conservation of historical heritage. Developing a good methodology for action is key to guaranteeing adequate preservation of cultural assets. With this in mind, the Spanish Historical Heritage Institute convened a conference in 2002 to try to define basic criteria to guide the different phases of the intervention process in stone materials in all stages of stone conservation: cleaning, consolidation and protection. Carrying out efficient protection of monuments in the traditional way focuses efforts only on how it affects the property, but not on the collateral impact it may have on the environment, or how the effects of climate change may alter its functionality. Thus, a more multidisciplinary test design is needed, with a mandatory laboratory simulation phase under simulated rainfall that represents the increased environmental aggressiveness expected in the near future due to climate change. Hence, water becomes a means to simulate these future conditions, but also a way to explore the effects on rivers and groundwater near the points where the monuments will be treated. Since fresh water is one of the resources that is expected to become scarce in the short term, we intend to carry out responsible tests that take into account both aspects: saving water use and water pollution. Combining the conservation of monuments and environmental responsibility, it will be shown how it is possible to carry out research to achieve a natural product that serves as a sustainable coating for monuments of stone material that is durable but that reduces the environmental impact both in the selection of the product and in the experimental phase, as well as in its operation after application.This research received funding from the Universidad de León (ULE-PoC 2018) and “Fundación General de la ULE y de la Empresa (FGULEM)” under project 2019/00149/001, from the “Consejería de Educación-Desafíos 2020” and the “Consejería de Turismo-PRESERVARTE project” of the Region of Castilla y León, and the granted MICINN project (PID2020-120439RA-I00).Peer reviewe

Prevalencia de fibrilación auricular y características de la fibrilación auricular no valvular en la población general. Registro AFINVA

Fundamento y objetivos: La fibrilación auricular es la arritmia mantenida más común. El estudio pretende conocer la prevalencia de fibrilación auricular en la población general, y evaluar las características y el manejo de los casos con fibrilación auricular no valvular. Métodos: Estudio transversal exploratorio en una muestra de la población de un Departamento de Salud (n = 30.024) de sujetos mayores de 18 años con diagnóstico electrocardiográfico de fibrilación auricular en la historia clínica electrónica de atención primaria. Se analizan características clínicas, manejo y tratamiento. Resultados: De un total de 629 pacientes con diagnóstico de fibrilación auricular, lo que representa una prevalencia del 2,1% (8,06% en > 65 años), fueron seleccionados para el estudio 505 casos con fibrilación auricular no valvular. La edad media fue 77,4 ± 10 años, 55% mujeres. Se objetivó cardiopatía estructural en el 32% de casos e insuficiencia cardiaca en el 29,5%. El 72% de pacientes recibía tratamiento anticoagulante, 60% con antivitamina K y 12% con anticoagulantes directos. Entre los primeros, solo el 53% mantenía un tiempo en rango terapéutico ≥ 65% según el método de Rosendaal. La forma de presentación persistente-permanente fue más frecuente (60,8%), seguida de la paroxística (39,2%). Conclusiones: La prevalencia de fibrilación auricular fue del 2,1%, aumentando con la edad, con elevada proporción de cardiopatía concomitante. La proporción de pacientes anticoagulados y la calidad de la anticoagulación son deficientes, revelándose así la necesidad de mejor monitorización y mayor utilización de nuevos anticoagulantes directos en los casos indicados

Lineage Plasticity in SCLC Generates Non-Neuroendocrine Cells Primed for Vasculogenic Mimicry

INTRODUCTION: Vasculogenic mimicry (VM), the process of tumor cell transdifferentiation to endow endothelial-like characteristics supporting de novo vessel formation, is associated with poor prognosis in several tumor types, including SCLC. In genetically engineered mouse models (GEMMs) of SCLC, NOTCH, and MYC co-operate to drive a neuroendocrine (NE) to non-NE phenotypic switch, and co-operation between NE and non-NE cells is required for metastasis. Here, we define the phenotype of VM-competent cells and molecular mechanisms underpinning SCLC VM using circulating tumor cell-derived explant (CDX) models and GEMMs.METHODS: We analyzed perfusion within VM vessels and their association with NE and non-NE phenotypes using multiplex immunohistochemistry in CDX, GEMMs, and patient biopsies. We evaluated their three-dimensional structure and defined collagen-integrin interactions.RESULTS: We found that VM vessels are present in 23/25 CDX models, 2 GEMMs, and in 20 patient biopsies of SCLC. Perfused VM vessels support tumor growth and only NOTCH-active non-NE cells are VM-competent in vivo and ex vivo, expressing pseudohypoxia, blood vessel development, and extracellular matrix organization signatures. On Matrigel, VM-primed non-NE cells remodel extracellular matrix into hollow tubules in an integrin β1-dependent process.CONCLUSIONS: We identified VM as an exemplar of functional heterogeneity and plasticity in SCLC and these findings take considerable steps toward understanding the molecular events that enable VM. These results support therapeutic co-targeting of both NE and non-NE cells to curtail SCLC progression and to improve the outcomes of patients with SCLC in the future.</p

A Network of Macrophages Supports Mitochondrial Homeostasis in the Heart

Cardiomyocytes are subjected to the intense mechanical stress and metabolic demands of the beating heart. It is unclear whether these cells, which are long-lived and rarely renew, manage to preserve homeostasis on their own. While analyzing macrophages lodged within the healthy myocardium, we discovered that they actively took up material, including mitochondria, derived from cardiomyocytes. Cardiomyocytes ejected dysfunctional mitochondria and other cargo in dedicated membranous particles reminiscent of neural exophers, through a process driven by the cardiomyocyte's autophagy machinery that was enhanced during cardiac stress. Depletion of cardiac macrophages or deficiency in the phagocytic receptor Mertk resulted in defective elimination of mitochondria from the myocardial tissue, activation of the inflammasome, impaired autophagy, accumulation of anomalous mitochondria in cardiomyocytes, metabolic alterations, and ventricular dysfunction. Thus, we identify an immune-parenchymal pair in the murine heart that enables transfer of unfit material to preserve metabolic stability and organ function.
