Scientific dissemination in the Instituto Español de OceanografĂa (IEO): Best practices in recent years
There is a growing interest and obligations to
bring the results of scientific research closer to society. In this
sense, the Instituto Español de OceanografĂa (IEO, CSIC) has
acquired in recent years an institutional commitment with the
scientific dissemination, carrying out some projects on this
topic. The objective of these projects is to visualize and value
their research and results in different formats increasing the
scientific culture of society that demand and financed most of
public research. In the present work four successful initiatives
or projects are presented. Diversimar project is a citizen
science tool for the observation of the marine and fishing
biodiversity of Galicia and the Cantabrian Sea. Mar interior
project brings activity of IEO to society with face-to-face
conferences and workshops. Planet Tuna project combines
science with art through an online platform to enhance the
scientific knowledge of tuna and other big pelagics for their
sustainability. To end, the interactive book â45 days on the
Flemish Cap Bankâ spreads the technical and human effort of
an oceanographic survey that remains behind the fisheries
management developed by the IEO. The objective of the
present study is to make visible and put in value these projects
and serve as inspiration.VersiĂłn del edito
Understanding the impact of brain disorders: Towards a 'horizontal epidemiology' of psychosocial difficulties and their determinants
Objective
To test the hypothesis of âhorizontal epidemiologyâ, i.e. that psychosocial difficulties (PSDs),
such as sleep disturbances, emotional instability and difficulties in personal interactions,
and their environmental determinants are experienced in common across neurological and
psychiatric disorders, together called brain disorders.
Study Design
A multi-method study involving systematic literature reviews, content analysis of patientreported
outcomes and outcome instruments, clinical input and a qualitative study was
carried out to generate a pool of PSD and environmental determinants relevant for nine different
brain disorders, namely epilepsy, migraine, multiple sclerosis, Parkinsonâs disease,
stroke, dementia, depression, schizophrenia and substance dependency. Information from
these sources was harmonized and compiled, and after feedback from external experts, a
data collection protocol including PSD and determinants common across these nine disorders
was developed. This protocol was implemented as an interview in a cross-sectional

Bcr/Abl Interferes with the Fanconi Anemia/BRCA Pathway: Implications in the Chromosomal Instability of Chronic Myeloid Leukemia Cells
Chronic myeloid leukemia (CML) is a malignant clonal disorder of the hematopoietic system caused by the expression of the BCR/ABL fusion oncogene. Although it is well known that CML cells are genetically unstable, the mechanisms accounting for this genomic instability are still poorly understood. Because the Fanconi anemia (FA) pathway is believed to control several mechanisms of DNA repair, we investigated whether this pathway was disrupted in CML cells. Our data show that CML cells have a defective capacity to generate FANCD2 nuclear foci, either in dividing cells or after DNA damage. Similarly, human cord blood CD34+ cells transduced with BCR/ABL retroviral vectors showed impaired FANCD2 foci formation, whereas FANCD2 monoubiquitination in these cells was unaffected. Soon after the transduction of CD34+ cells with BCR/ABL retroviral vectors a high proportion of cells with supernumerary centrosomes was observed. Similarly, BCR/ABL induced a high proportion of chromosomal abnormalities, while mediated a cell survival advantage after exposure to DNA cross-linking agents. Significantly, both the impaired formation of FANCD2 nuclear foci, and also the predisposition of BCR/ABL cells to develop centrosomal and chromosomal aberrations were reverted by the ectopic expression of BRCA1. Taken together, our data show for the first time a disruption of the FA/BRCA pathway in BCR/ABL cells, suggesting that this defective pathway should play an important role in the genomic instability of CML by the co-occurrence of centrosomal amplification and DNA repair deficiencies
Atlas de las praderas marinas de España
Knowledge of the distribution and extent of seagrass habitats is currently the basis of management and conservation policies of the coastal zones in most European countries. This basic information is being requested through European directives for the establishment of monitoring programmes and the implementation of specific actions to preserve the marine environment. In addition, this information is crucial for the quantification of the ecological importance usually attributed to seagrass habitats due to, for instance, their involvement in biogeochemical cycles, marine biodiversity and quality of coastal waters or global carbon budgets. The seagrass atlas of Spain represents a huge collective effort performed by 84 authors across 30 Spanish institutions largely involved in the scientific research, management and conservation of seagrass habitats during the last three decades. They have contributed to the availability of the most precise and realistic seagrass maps for each region of the Spanish coast which have been integrated in a GIS to obtain the distribution and area of each seagrass species. Most of this information has independently originated at a regional level by regional governments, universities and public research organisations, which explain the elevated heterogeneity in criteria, scales, methods and objectives of the available information. On this basis, seagrass habitats in Spain occupy a total surface of 1,541,63 km2, 89% of which is concentrated in the Mediterranean regions; the rest is present in sheltered estuarine areas of the Atlantic peninsular regions and in the open coastal waters of the Canary Islands, which represents 50% of the Atlantic meadows. Of this surface, 71.5% corresponds to Posidonia oceanica, 19.5% to Cymodocea nodosa, 3.1% to Zostera noltii (=Nanozostera noltii), 0.3% to Zostera marina and 1.2% to Halophila decipiens. Species distribution maps are presented (including Ruppia spp.), together with maps of the main impacts and pressures that has affected or threatened their conservation status, as well as the management tools established for their protection and conservation. Despite this considerable effort, and the fact that Spain has mapped wide shelf areas, the information available is still incomplete and with weak precision in many regions, which will require an investment of major effort in the near future to complete the whole picture and respond to demands of EU directives

Human IRF1 governs macrophagic IFN-Îł immunity to mycobacteria
Inborn errors of human IFN-Îł-dependent macrophagic immunity underlie mycobacterial diseases, whereas inborn errors of IFN-α/ÎČ-dependent intrinsic immunity underlie viral diseases. Both types of IFNs induce the transcription factor IRF1. We describe unrelated children with inherited complete IRF1 deficiency and early-onset, multiple, life-threatening diseases caused by weakly virulent mycobacteria and related intramacrophagic pathogens. These children have no history of severe viral disease, despite exposure to many viruses, including SARS-CoV-2, which is life-threatening in individuals with impaired IFN-α/ÎČ immunity. In leukocytes or fibroblasts stimulated in vitro, IRF1-dependent responses to IFN-Îł are, both quantitatively and qualitatively, much stronger than those to IFN-α/ÎČ. Moreover, IRF1-deficient mononuclear phagocytes do not control mycobacteria and related pathogens normally when stimulated with IFN-Îł. By contrast, IFN-α/ÎČ-dependent intrinsic immunity to nine viruses, including SARS-CoV-2, is almost normal in IRF1-deficient fibroblasts. Human IRF1 is essential for IFN-Îł-dependent macrophagic immunity to mycobacteria, but largely redundant for IFN-α/ÎČ-dependent antiviral immunity
Clonal Hematopoiesis and Risk of Progression of Heart Failure With Reduced Left Ventricular Ejection Fraction.
BACKGROUND
Clonal hematopoiesis driven by somatic mutations in hematopoietic cells, frequently called clonal hematopoiesis of indeterminate potential (CHIP), has been associated with adverse cardiovascular outcomes in population-based studies and in patients with ischemic heart failure (HF) and reduced left ventricular ejection fraction (LVEF). Yet, the impact of CHIP on HF progression, including nonischemic etiology, is unknown.
OBJECTIVES
The purpose of this study was to assess the clinical impact of clonal hematopoiesis on HF progression irrespective of its etiology.
METHODS
The study cohort comprised 62 patients with HF and LVEFÂ 2% in 54 genes. Patients were followed for at least 3.5 years for various adverse events including death, HF-related death, and HF hospitalization.
RESULTS
CHIP mutations were detected in 24 (38.7%) patients, without significant differences in all-cause mortality (p = 0.151). After adjusting for risk factors, patients with mutations in either DNA methyltransferase 3 alpha (DNMT3A) or Tet methylcytosine dioxygenase 2 (TET2) exhibited accelerated HF progression in terms of death (hazard ratio [HR]: 2.79; 95% confidence interval [CI]: 1.31 to 5.92; p = 0.008), death or HF hospitalization (HR: 3.84; 95% CI: 1.84 to 8.04; p < 0.001) and HF-related death or HF hospitalization (HR: 4.41; 95% CI: 2.15 to 9.03; p < 0.001). In single gene-specific analyses, somatic mutations in DNMT3A or TET2 retained prognostic significance with regard to HF-related death or HF hospitalization (HR: 4.50; 95% CI: 2.07 to 9.74; p < 0.001, for DNMT3A mutations; HR: 3.18; 95% CI: 1.52 to 6.66; p = 0.002, for TET2 mutations). This association remained significant irrespective of ischemic/nonischemic etiology.
CONCLUSIONS
Somatic mutations that drive clonal hematopoiesis are common among HF patients with reduced LVEFÂ and are associated with accelerated HF progression regardless of etiology.S
Micrometric rods grown by nanosecond pulsed laser deposition ofboron carbide
Micrometric size rods have been fabricated via pulsed laser deposition in vacuum from boron carbidetargets using nanosecond pulses of 1064 and 266 nm and room temperature Si (1 0 0) substrates. Mor-phological, structural and chemical characterization of the microrods was made by applying scanningelectron microscopy, focussed ion beam microscopy coupled to secondary ion mass spectrometry, X-ray diffraction, X-ray photoelectron spectroscopy and micro-Raman spectroscopy. Ablation at 1064 nmfavours the formation of microrods with high aspect ratio, sharp edges and pyramidal tips, typically 10 mlong with a cross section of around 2 m Ă 2 m. Differently, at 266 nm the microrods are of smaller sizeand present a more globular aspect. The analyses of the microrods provide information about their crys-talline nature and composition, based on a mixture which includes boron, boron oxide and boron carbide,and allows discussion of the wavelength dependent growth mechanisms involved.Peer reviewe
An Interdisciplinary Assessment of Private Conservation Areas in the Western United States
Conservation easements are the fastest growing private conservation strategy in the United States. However, mechanisms to assess private land conservation as well as their support by the general public are not well understood. This study uses the ecosystem services framework for assessing existing private lands in Idaho and identifies areas for future conservation easements. Using conservation targets of the land trust as a guide for selecting ecosystem services, we (a) mapped the spatial delivery of conservation targets across public and private lands, (b) explored public awareness in terms of social importance and vulnerability, and (c) mapped future priority areas by characterizing conservation bundles. We found that public lands provided the highest levels of conservation targets, and we found no difference in conservation target provision between private areas and conservation easements. The spatial characterization of conservation target bundles identified potential future priority areas for conservation easements, which can guide planning of land trust conservation efforts
Decoding Aging: Understanding the Complex Relationship among Aging, Free Radicals, and GSH
N-aryl maleimides can undergo a 1,4-Michael-type addition reaction with reduced glutathione (GSH), leading to a decreased concentration of GSH and an increased concentration of free radicals (FRs) in cells. GSH is a critical scavenging molecule responsible for protecting cells from oxidation and for maintaining redox homeostasis. N-aryl maleimides disturb redox homeostasis in cells because they scavenge thiol-containing molecules, especially GSH. This study aimed at measuring the concentrations of GSH and FRs by electronic paramagnetic resonance (EPR), in the brain and liver tissue of male Wistar rats (ex vivo) at different ages and after treatment with 3,5-dimaleimylbenzoic acid (3,5-DMB). Our results showed a relationship between age and the concentrations of GSH and FRs in cells. In young rats, the concentration of GSH was higher than in old rats, while the concentration of FRs was higher in adult rats than in young rats, suggesting an inverse relationship between GSH and FRs. On the other hand, the reaction of 3,5-DMB (an electrophilic maleimide) with cellular GSH increased the FR content. The results of this study contribute to the awareness that the process of aging implies not only a loss of tissue function but also essential changes in the molecular contents of cells, especially the concentrations of FRs and GSH
