Evidencias de terremotos cuaternarios en una sima hipogénica: La Sima de Benís (Murcia, SE España)

La interacción entre una cueva hipogénica y la actividad de una falla cuaternaria es la principal responsable de la génesis de la cueva más profunda de la Región de Murcia y una de las mayores cavidades hipogénicas del sur de la península. La Sima de Benís presenta una amplia y única variedad de espeleotemas y de estructuras de disolución que se encuentran afectadas por deformaciones sísmicas producidas tanto por paleoterremotos durante el Pleistoceno Superior, como por terremotos instrumentales (Mw 4,8; VI EMS-98, 1999; Mula). Además, dentro de las zonas más profundas de la cueva aparecen restos fósiles “in situ” de macromamíferos (Lynx pardinus spelaeus), los cuales hemos relacionado con la actividad sísmica en el interior de la caverna. En cuanto a su topografía, esta cavidad presenta dos sectores bien diferenciados: (1) un primer sector de 150-160 m de desarrollo vertical con pozos de origen hipogénico con desarrollo de golpes de gubia y conductos de disolución ascendentes (con “outlets” y “megascallops”) y (2) un segundo sector entre los 150 - 160 m y los 320 m de profundidad, el cual se desarrolla sobre un plano de falla normal de dirección N-S (Falla de Benís). Este segundo sector de la sima es el que presenta evidencias paleosísmicas cuaternarias, dividiéndose a su vez en dos zonas en relación a la dinámica kárstica dominante: (2.a) una zona vadosa dominada por estructuras hipogénicas (donde aparecen folias y corales), junto con marcas cinemáticas de movimiento de la falla (estrías con recristalizaciones y concreciones carbonatadas) y (2.b) una zona freática profunda controlada por la precipitación de nubes de calcita bajo lámina de agua y de tamaño métrico que se desarrolla hasta los - 320 m de profundidad. En cuanto a la parte hipogénica superior de la sima, se desarrolla a favor de una fractura con relleno de calcita y de orientación E-W sobre carbonatos del Cretácico superior y el Paleoceno, con un espesor centimétrico y evidencias de relleno posterior y circulación de fluidos. La potencial actividad paleosísmica ha podido ser datada en 65 ± 17,6 ka (OIS 4) mediante el análisis de racemización de aminoácidos de los colmillos de un lince de las cavernas, el cual pudo ser afectado por un terremoto. Por último, se ha estimado el tamaño del último sismo relacionado con la actividad de la falla a partir de relaciones empíricas, con un valor de Mw oscilando entre 5,5 y 6. Para ello se ha estimado la longitud en superficie de la traza de falla que controla la cueva en profundidad y se ha comparado con el último salto cosísmico observable en el interior de la sima. Estimaciones del salto de falla acumulado y la datación del último paleoterremoto, sugieren que parte de la evolución hipogénica con paleoterremotos de esta cavidad de forma conjunta se produjo al menos, desde hace 250 ka (OIS 7)

Ruxolitinib in refractory acute and chronic graft-versus-host disease : a multicenter survey study

Graft-versus-host disease is the main cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. First-line treatment is based on the use of high doses of corticosteroids. Unfortunately, second-line treatment for both acute and chronic graft-versus-host disease, remains a challenge. Ruxolitinib has been shown as an effective and safe treatment option for these patients. Seventy-nine patients received ruxolitinib and were evaluated in this retrospective and multicenter study. Twenty-three patients received ruxolitinib for refractory acute graft-versus-host disease after a median of 3 (range 1-5) previous lines of therapy. Overall response rate was 69.5% (16/23) which was obtained after a median of 2 weeks of treatment, and 21.7% (5/23) reached complete remission. Fifty-six patients were evaluated for refractory chronic graft-versus-host disease. The median number of previous lines of therapy was 3 (range 1-10). Overall response rate was 57.1% (32/56) with 3.5% (2/56) obtaining complete remission after a median of 4 weeks. Tapering of corticosteroids was possible in both acute (17/23, 73%) and chronic graft-versus-host disease (32/56, 57.1%) groups. Overall survival was 47% (CI: 23-67%) at 6 months for patients with aGVHD (62 vs 28% in responders vs non-responders) and 81% (CI: 63-89%) at 1 year for patients with cGVHD (83 vs 76% in responders vs non-responders). Ruxolitinib in the real life setting is an effective and safe treatment option for GVHD, with an ORR of 69.5% and 57.1% for refractory acute and chronic graft-versus-host disease, respectively, in heavily pretreated patients

The Tree Biodiversity Network (BIOTREE-NET): prospects for biodiversity research and conservation in the Neotropics

Biodiversity research and conservation efforts in the tropics are hindered by the lack of knowledge of the assemblages found there, with many species undescribed or poorly known. Our initiative, the Tree Biodiversity Network (BIOTREE-NET), aims to address this problem by assembling georeferenced data from a wide range of sources, making these data easily accessible and easily queried, and promoting data sharing. The database (GIVD ID NA-00-002) currently comprises ca. 50,000 tree records of ca. 5,000 species (230 in the IUCN Red List) from \u3e2,000 forest plots in 11 countries. The focus is on trees because of their pivotal role in tropical forest ecosystems (which contain most of the world\u27s biodiversity) in terms of ecosystem function, carbon storage and effects on other species. BIOTREE-NET currently focuses on southern Mexico and Central America, but we aim to expand coverage to other parts of tropical America. The database is relational, comprising 12 linked data tables. We summarise its structure and contents. Key tables contain data on forest plots (including size, location and date(s) sampled), individual trees (including diameter, when available, and both recorded and standardised species name), species (including biological traits of each species) and the researchers who collected the data. Many types of queries are facilitated and species distribution modelling is enabled. Examining the data in BIOTREE-NET to date, we found an uneven distribution of data in space and across biomes, reflecting the general state of knowledge of the tropics. More than 90% of the data were collected since 1990 and plot size varies widely, but with most less than one hectare in size. A wide range of minimum sizes is used to define a \u27tree\u27. The database helps to identify gaps that need filling by further data collection and collation. The data can be publicly accessed through a web application at http://portal.biotreenet.com. Researchers are invited and encouraged to contribute data to BIOTREE-NET

SUMOylation controls Hu antigen R posttranscriptional activity in liver cancer

© 2024 The Author(s). This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/).The posttranslational modification of proteins critically influences many biological processes and is a key mechanism that regulates the function of the RNA-binding protein Hu antigen R (HuR), a hub in liver cancer. Here, we show that HuR is SUMOylated in the tumor sections of patients with hepatocellular carcinoma in contrast to the surrounding tissue, as well as in human cell line and mouse models of the disease. SUMOylation of HuR promotes major cancer hallmarks, namely proliferation and invasion, whereas the absence of HuR SUMOylation results in a senescent phenotype with dysfunctional mitochondria and endoplasmic reticulum. Mechanistically, SUMOylation induces a structural rearrangement of the RNA recognition motifs that modulates HuR binding affinity to its target RNAs, further modifying the transcriptomic profile toward hepatic tumor progression. Overall, SUMOylation constitutes a mechanism of HuR regulation that could be potentially exploited as a therapeutic strategy for liver cancer.This work was supported by grants to M.L.M.-C. from Departamento de Industria del Gobierno Vasco, Spain; Ministerio de Ciencia e Innovación, Spain (grant no.

Diseño para el desarrollo sustentable y la habitabilidad segura e incluyente

Este libro se divide en dos partes que permiten permear en el campo de la enseñanza del diseño; la primera se enfoca en temáticas que se desprenden del diseño en la educación para la sustentabilidad; en la segunda, se identifican las tendencias del diseño como un modo de verlo y sentirlo: va desde el diseño emocional hacia uno de conservación, reúso y reparación de objetos para reducir el consumo de recursos materiales

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

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
