Los huevos en La Colmena

Las lenguas proponen interesantes juegos de recepción. En el español de nuestro país, por ejemplo, con la palabra ‘huevos’ nos referimos a los genitales masculinos, mientras que en italiano se trata del título del libro de poemas de Elisa Biagini (Florencia, Italia, 1970). Lo interesante surge cuando nos enteramos de que ‘huevo’ en italiano es masculino al singular y femenino al plural. El poemario de Biagini juega con esa transición de géneros. En el tantas veces atacado ‘horizonte masculino’ de la poesía italiana nace esta voz que llena de intenciones las imágenes. No hay referencias directas, sino el gesto hábil que sólo la poesía puede producir en el juego de la palabra. Biagini propone combatir la discursividad masculina de su tradición desde la dispersión de su voz: elabora figuras femeninas que aman hombres y mujeres, que son niñas, amantes y madres, sin necesidad de renunciar a la perversidad y al humor. El ejemplo más claro de esto es el poema “Feminist icon”, donde la misma mano que acaba de masturbarse hace la señal de la cruz entre el cuerpo y un burro de planchar.Biagini ha publicado tres libros de poemas: Questi nodi (Florencia, Gazebo, 1993), Uova (Génova, Zona, 1999) y l’ospite (Torino, Einaudi, 2004). Los poemas aquí traducidos fueron tomados de una antología personal

Mantener viva, al menos la palabra

Sección a cargo de José MolinaLas palabras viven dentro del poema en tanto los seres humanos, en ocasiones, sólo existimos. Esto es lo que parece indicar la poesía de Anna Casalino. Para la poeta, la realidad es una luz que ilumina la habitación, el resto es apenas un martilleo de objetividad (palabra muy cara dentro de su trabajo).Anna Casalino vive en Roma y trabaja como maestra de secundaria. Los poemas traducidos aquí pertenecen al libro L'esilio e il regno (2003)

Dissecting the microglial response in transgenic models of amyloidogenesis and tauopathy

Amyloid-beta (Abeta) peptide deposits and hyperphosphorylated tau protein (phospho-tau) accumulate in Alzheimer’s disease (AD) brains. These abnormal protein aggregates leads to glial activation, synaptic dysfunction, neuronal loss and cognitive decline. While microglial response has mostly been analyzed in relation to Abeta accumulation, little is still known about inflammatory processes associated with tau pathology. Microglial reactivity and defective glial responses have been involved in these proteinopathies. Our aim is to clarify the effects of Abeta and tau separately, in order to improve the comprehension of their differential contribution to neuroinflammation and neurodegeneration. We compared the progression of these processes in an amyloidogenic AD model (APPSL/PS1M146L) and two different models of tauopathy (ThyTau22 and hP301S) from 2 to 18 months of age. Accumulation of aggregated proteins was assessed using specific anti- Abeta and phospho-tau antibodies. Inflammatory response was studied using a battery of microglial markers (Iba1, CD45, CD68, Trem2 and Gal-3). In the hippocampus of these models, Tau and Abeta pathologies initiated as early as 2 months of age and increased progressively with aging. Neuritic plaques induced a strong microglial activation associated to plaques in APP/PS1 mice. Interestingly, inflammatory markers and microglial reactivity were barely increased in the hippocampus of ThyTau mice in contrast to not only APP/PS1, but also to P301S mice, which displayed a prominent microglial response. Deciphering the specific effects of Abeta, tau and their different toxic species, would indeed enable the development of novel therapeutic strategies and drugs targeting neuroinflammatory pathways related to these proteinopathies.Universidad de Málaga.

Recommendations for SARS-CoV- 2/ COVID-19 testing: a scoping review of current guidance

Background Testing used in screening, diagnosis and follow-up of COVID-19 has been a subject of debate. Several organisations have developed formal advice about testing for COVID-19 to assist in the control of the disease. We collated, delineated and appraised current worldwide recommendations about the role and applications of tests to control SARS-CoV- 2/COVID-19. Methods We searched for documents providing recommendations for COVID-19 testing in PubMed, EMBASE, LILACS, the Coronavirus Open Access Project living evidence database and relevant websites such as TRIP database, ECRI Guidelines Trust, the GIN database, from inception to 21 September 2020. Two reviewers applied the eligibility criteria to potentially relevant citations without language or geographical restrictions. We extracted data in duplicate, including assessment of methodological quality using the Appraisal of Guidelines for Research and Evaluation-II tool. Results We included 47 relevant documents and 327 recommendations about testing. Regarding the quality of the documents, we found that the domains with the lowest scores were ‘Editorial independence’ (Median=4%) and ‘Applicability’ (Median=6%). Only six documents obtained at least 50% score for the ‘Rigour of development’ domain. An important number of recommendations focused on the diagnosis of suspected cases (48%) and deisolation measures (11%). The most frequently recommended test was the reverse transcription-PCR (RT-PCR) assay (87 recommendations) and the chest CT (38 recommendations). There were 22 areas of agreement among guidance developers, including the use of RT-PCR for SARS-Cov- 2 confirmation, the limited role of bronchoscopy, the use chest CT and chest X-rays for grading severity and the co-assessment for other respiratory pathogens. Conclusion This first scoping review of recommendations for COVID-19 testing showed many limitations in the methodological quality of included guidance documents that could affect the confidence of clinicians in their implementation. Future guidance documents should incorporate a minimum set of key methodological characteristics to enhance their applicability for decision making.Instituto de Salud Carlos III 2017/CD17/00219European Social Fund 2014-2020, 'Investing in your future'Spanish Governmen

A dense neural network approach for detecting clone ID attacks on the RPL protocol of the IoT

At present, new data sharing technologies, such as those used in the Internet of Things (IoT) paradigm, are being extensively adopted. For this reason, intelligent security controls have become imperative. According to good practices and security information standards, particularly those regarding security in depth, several defensive layers are required to protect information assets. Within the context of IoT cyber-attacks, it is fundamental to continuously adapt new detection mechanisms for growing IoT threats, specifically for those becoming more sophisticated within mesh networks, such as identity theft and cloning. Therefore, current applications, such as Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), and Security Information and Event Management Systems (SIEM), are becoming inadequate for accurately handling novel security incidents, due to their signature-based detection procedures using the matching and flagging of anomalous patterns. This project focuses on a seldom-investigated identity attack—the Clone ID attack—directed at the Routing Protocol for Low Power and Lossy Networks (RPL), the underlying technology for most IoT devices. Hence, a robust Artificial Intelligence-based protection framework is proposed, in order to tackle major identity impersonation attacks, which classical applications are prone to misidentifying. On this basis, unsupervised pre-training techniques are employed to select key characteristics from RPL network samples. Then, a Dense Neural Network (DNN) is trained to maximize deep feature engineering, with the aim of improving classification results to protect against malicious counterfeiting attempts

Association of Candidate Gene Polymorphisms With Chronic Kidney Disease: Results of a Case-Control Analysis in the Nefrona Cohort

Chronic kidney disease (CKD) is a major risk factor for end-stage renal disease, cardiovascular disease and premature death. Despite classical clinical risk factors for CKD and some genetic risk factors have been identified, the residual risk observed in prediction models is still high. Therefore, new risk factors need to be identified in order to better predict the risk of CKD in the population. Here, we analyzed the genetic association of 79 SNPs of proteins associated with mineral metabolism disturbances with CKD in a cohort that includes 2, 445 CKD cases and 559 controls. Genotyping was performed with matrix assisted laser desorption ionizationtime of flight mass spectrometry. We used logistic regression models considering different genetic inheritance models to assess the association of the SNPs with the prevalence of CKD, adjusting for known risk factors. Eight SNPs (rs1126616, rs35068180, rs2238135, rs1800247, rs385564, rs4236, rs2248359, and rs1564858) were associated with CKD even after adjusting by sex, age and race. A model containing five of these SNPs (rs1126616, rs35068180, rs1800247, rs4236, and rs2248359), diabetes and hypertension showed better performance than models considering only clinical risk factors, significantly increasing the area under the curve of the model without polymorphisms. Furthermore, one of the SNPs (the rs2248359) showed an interaction with hypertension, being the risk genotype affecting only hypertensive patients. We conclude that 5 SNPs related to proteins implicated in mineral metabolism disturbances (Osteopontin, osteocalcin, matrix gla protein, matrix metalloprotease 3 and 24 hydroxylase) are associated to an increased risk of suffering CKD

Impaired Condensin Complex and Aurora B kinase underlie mitotic and chromosomal defects in hyperdiploid B-cell ALL

B-cell acute lymphoblastic leukemia (B-ALL) is the most common pediatric cancer, and high-hyperdiploidy (HyperD) identifies the most common subtype of pediatric B-ALL. Despite HyperD is an initiating oncogenic event affiliated to childhood B-ALL, the mitotic and chromosomal defects associated to HyperD B-ALL (HyperD-ALL) remain poorly characterized. Here, we have used 54 primary pediatric B-ALL samples to characterize the cellular-molecular mechanisms underlying the mitotic/chromosome defects predicated to be early pathogenic contributors in HyperD-ALL. We report that HyperD-ALL blasts are low proliferative and show a delay in early mitosis at prometaphase, associated to chromosome alignment defects at the metaphase plate leading to robust chromosome segregation defects and non-modal karyotypes. Mechanistically, biochemical, functional and mass-spectrometry assays revealed that condensin complex is impaired in HyperD-ALL cells, leading to chromosome hypocondensation, loss of centromere stiffness and mis-localization of the chromosome passenger complex proteins Aurora B Kinase (AURKB) and Survivin in early mitosis. HyperD-ALL cells show chromatid cohesion defects and impaired spindle assembly checkpoint (SAC) thus undergoing mitotic slippage due to defective AURKB and impaired SAC activity, downstream of condensin complex defects. Chromosome structure/condensation defects and hyperdiploidy were reproduced in healthy CD34+ stem/progenitor cells upon inhibition of AURKB and/or SAC. Collectively, hyperdiploid B-ALL is associated to defective condensin complex, AURKB and SAC

Cada trabajo del libro incluye conclusiones para los interesados en las temáticas aludidas y en ellos nos enteramos de aspectos como los siguientes: - El mayor incremento del precio de los insumos como el maíz, sorgo y en menor medida desperdicio de pan, en relación con el menor crecimiento del precio del ganado en pie, dará como consecuencia un desabasto de carne bovina. - El agua es un recurso primordial en las zonas áridas y semiáridas de México, en tanto que su aporte limita la producción de la agricultura. En este estudio se observó que el precio real del agua es muy bajo en relación a otras zonas agrícolas del mundo. - Hoy en día en el país se consumen alrededor de 718 mil barriles diarios de gasolinas, un aproximado de 113.7 millones de litros, una cantidad tan grande que nuestro país se ve en la necesidad de importar cerca del 39 % de las gasolinas que consumimos. - Los jaliscienses radicados en Estados Unidos tienen una mayor capacidad de financiamiento del bienestar en la entidad, que el propio gobierno de ese estado. - México continuará basando sus finanzas públicas y su política de desarrollo económico en la extracción de combustibles fósiles (petróleo). Este modelo acelerará el deterioro y agotamiento de los recursos naturales. -La importancia de la agricultura orgánica radica en que retoma los tres ámbitos de la sustentabilidad; el ámbito ambiental, el económico y el social. - Es fundamental motivar la organización de los productores de haba para que ellos puedan captar una mayor proporción de los altos márgenes de precios que los consumidores están dispuestos a pagar. - Las condiciones del clima afectan a la producción agraria. Debido al fenómeno de cambio climático, es necesario contar con herramientas informáticas que proporcionen información climatológica para poder tomar medidas preventivas a favor de una mayor cantidad y calidad de producción. La herramienta de software permite la consulta del clima por localidades evitando la necesidad de contar con una estación meteorológica
