Microsyntenic Clusters Reveal Conservation of lncRNAs in Chordates Despite Absence of Sequence Conservation
Homologous long non-coding RNAs (lncRNAs) are elusive to identify by sequence similarity due to their fast-evolutionary rate. Here we develop LincOFinder, a pipeline that finds conserved intergenic lncRNAs (lincRNAs) between distant related species by means of microsynteny analyses. Using this tool, we have identified 16 bona fide homologous lincRNAs between the amphioxus and human genomes. We characterized and compared in amphioxus and Xenopus the expression domain of one of them, Hotairm1, located in the anterior part of the Hox cluster. In addition, we analyzed the function of this lincRNA in Xenopus, showing that its disruption produces a severe headless phenotype, most probably by interfering with the regulation of the Hox cluster. Our results strongly suggest that this lincRNA has probably been regulating the Hox cluster since the early origin of chordates. Our work pioneers the use of syntenic searches to identify non-coding genes over long evolutionary distances and helps to further understand lncRNA evolution
NLRP3 inflammasome suppression improves longevity and prevents cardiac aging in male mice
While NLRP3‐inflammasome has been implicated in cardiovascular diseases, its role
in physiological cardiac aging is largely unknown. During aging, many alterations
occur in the organism, which are associated with progressive impairment of metabolic
pathways related to insulin resistance, autophagy dysfunction, and inflammation.
Here, we investigated the molecular mechanisms through which NLRP3 inhibition
may attenuate cardiac aging. Ablation of NLRP3‐inflammasome protected mice from
age‐related increased insulin sensitivity, reduced IGF‐1 and leptin/adiponectin ratio
levels, and reduced cardiac damage with protection of the prolongation of the agedependent
PR interval, which is associated with atrial fibrillation by cardiovascular
aging and reduced telomere shortening. Furthermore, old NLRP3 KO mice showed an
inhibition of the PI3K/AKT/mTOR pathway and autophagy improvement, compared
with old wild mice and preserved Nampt‐mediated NAD+ levels with increased SIRT1
protein expression. These findings suggest that suppression of NLRP3 prevented
many age‐associated changes in the heart, preserved cardiac function of aged mice
and increased lifespan.Andalusian regional government; Consejería

Chlorophyll a fluorescence illuminates a path connecting plant molecular biology to Earth-system science
Remote sensing methods enable detection of solar-induced chlorophyll a fluorescence. However, to unleash the full potential of this signal, intensive cross-disciplinary work is required to harmonize biophysical and ecophysiological studies.For decades, the dynamic nature of chlorophyll a fluorescence (ChlaF) has provided insight into the biophysics and ecophysiology of the light reactions of photosynthesis from the subcellular to leaf scales. Recent advances in remote sensing methods enable detection of ChlaF induced by sunlight across a range of larger scales, from using instruments mounted on towers above plant canopies to Earth-orbiting satellites. This signal is referred to as solar-induced fluorescence (SIF) and its application promises to overcome spatial constraints on studies of photosynthesis, opening new research directions and opportunities in ecology, ecophysiology, biogeochemistry, agriculture and forestry. However, to unleash the full potential of SIF, intensive cross-disciplinary work is required to harmonize these new advances with the rich history of biophysical and ecophysiological studies of ChlaF, fostering the development of next-generation plant physiological and Earth-system models. Here, we introduce the scale-dependent link between SIF and photosynthesis, with an emphasis on seven remaining scientific challenges, and present a roadmap to facilitate future collaborative research towards new applications of SIF
Plan de Acción en España para la erradicación de la poliomelitis: Vigilancia de la Parálisis Flácida Aguda y Vigilancia de Enterovirus en España. Informe 2020
Centro Nacional de Epidemiología y Centro Nacional de Microbiología. ISCIII. Plan de acción en España para la Erradicación de la Poliomielitis. Vigilancia de la Parálisis Flácida Aguda y Vigilancia de Enterovirus en España, Informe año 2020. Madrid, 5 de noviembre de 2021.[ES] En España la situación libre de polio se monitoriza con la vigilancia de Parálisis Flácida Aguda (PFA) en niños menores de 15 años, como recomienda la Organización Mundial de la Salud (OMS). La vigilancia la realizan los servicios de vigilancia autonómicos y la red de laboratorios de PFA y a nivel nacional se coordina en el Centro Nacional de Epidemiología (CNE, ISCIII) y en el Laboratorio de Poliovirus del Centro Nacional de Microbiología (CNM, ISCIII). En el año 2020 en España no hubo casos de poliomielitis. Se notificaron 0,17 casos de PFA por 100.000 niños menores de 15 años, por debajo del objetivo de sensibilidad establecido por la OMS de un caso de PFA al año por cada 100.000 menores de 15 años. Solamente se detectaron enterovirus no-polio (EVNP) en las muestras de dos casos (EV-D68 y EV-B, respectivamente). En España también se realiza la vigilancia de EVNP en otros síndromes neurológicos para complementar el sistema de vigilancia de PFA. En las muestras investigadas en 2020 no se identificó ningún poliovirus y los EVNP más frecuentemente identificados fueron E-18, CV-A6 y E-21. Mientras haya circulación de poliovirus en el mundo hay que mantener activos los sistemas de vigilancia para detectar a tiempo cualquier importación de poliovirus. [EN] Spain monitors its polio-free status by conducting surveillance for cases of acute flaccid paralysis (AFP) in children less than 15 years of age, as recommended by the World Health Organization (WHO). The AFP surveillance is performed by the 19 Regional Epidemiological Surveillance Units and the AFP Surveillance Laboratory Network, coordinated at national level by the National Centre for Epidemiology (CNE. ISCIII) and the National Poliovirus Laboratory at Nacional Center of Microbiology (CNM. ISCIII) respectively. In 2020, no cases of poliomyelitis were reported from clinical surveillance; Spain reported 0.17 non-polio AFP cases per 100,000 children, below the WHO's performance criterion for a sensitive surveillance system (1 non-polio AFP cases per 100,000 children). The non-polio enteroviruses EV-D68, EV-B were identified from clinical specimens collected from AFP cases. Spain also performs enterovirus surveillance to complement the clinical system In 2020, non poliovirus were identified; The non-polioviruses E-18, CV-A6 y E-21 were the most frequently identified serotypes. As long as poliovirus is circulating in the world, surveillance systems must remain active to detect any importation of poliovirus in a timely manner.1. Resumen. 2. Introducción. 3.

CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative
Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research
Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
