Este artículo plantea una revisión del trabajo de arranque de las pinturas murales de Antonio Palomino en la bóveda y ábside de la iglesia de los Santos Juanes de Valencia llevado a cabo por el taller de los hermanos Gudiol de Barcelona entre 1958 y 1965 en un total de tres fases. Los actuales trabajos de restauración están revelando nueva información acerca del procedimiento concreto de arranque de estos frescos. Se ha podido conocer con mayor precisión la cronología de las diferentes fases de arranque y otros datos técnicos. Se ha analizado el estado del soporte mural que albergaba los paneles de madera con las pinturas y se han documentado las inscripciones que estaban ocultas bajo estos paneles. Ello nos ha permitido conocer detalles del modus operandi de una compleja operación de restauración que cuenta ya con más de 60 años

Caracterización genética, química y agronómica de líneas avanzadas de tomate de cáscara

Introducción. Conocer la diversidad a nivel genético, químico y morfológico que existe entre individuos y poblaciones, es de gran utilidad en los programas de mejoramiento genético, ya que facilita la organización del material y la selección adecuada de genotipos superiores para el desarrollo de una población mejorada. Objetivo. El objetivo del presente trabajo fue caracterizar genética, química y agronómicamente líneas avanzadas de tomate de cáscara (Physalis ixocarpa Brot.), del programa de mejoramiento de hortalizas del Campo Experimental Bajío (CE-Bajío) del Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP), México. Materiales y métodos. Durante la temporada primavera-verano y otoño-invierno de 2017, se cuantificó la variabilidad genética con marcadores moleculares de ADN de tipo AFLP (Amplified Fragment Length Polymorphism); se determinaron los compuestos fenólicos y tomatidina en fruto, y en lo agronómico el porcentaje de germinación, número de frutos por planta, peso del fruto, diámetro ecuatorial y polar, y el rendimiento. Resultados. Se obtuvo un promedio general de similitud entre los genotipos de 0,86. De acuerdo con las relaciones genéticas, se detectaron las líneas 4 y 70 como posibles progenitores de híbridos y un patrón geográfico en los agrupamientos. La diversidad química indicó que el mayor contenido de flavonoides (51,1 mg EAG/100 g) se presentó en la L-86, de fenoles y antocianinas (396, 8 y 7,22 mg EAG/100 g, resp.) en la L-182, y de taninos (188,4 mg EAG/100 g) en la L-97, mientras que la tomatidina fue mayor en frutos verdes (2,23-3,81 mg EAG/100 g) que en morados. El intervalo de rendimiento de las líneas fue de 11,4 a 47,6 t/ha, donde el 20% de las líneas superaron la media de rendimiento nacional (40 t/ha). Se destacó la L-37 con 47,6 t/ha, que además produjo mayor número de frutos por planta, diámetro ecuatorial y polar, y una tasa de germinación de 93,3%. Conclusión. Las líneas 37, 25, 27 y 167, tienen potencial para ser validadas para uso comercial y como líneas parentales

Association of Trabecular Bone Score with Inflammation and Adiposity in Patients with Psoriasis: Effect of Adalimumab Therapy

Studies on trabecular bone score (TBS) in psoriasis are lacking. We aim to assess the association between TBS and inflammation, metabolic syndrome features, and serum adipokines in 29 nondiabetic patients with psoriasis without arthritis, before and after 6-month adalimumab therapy. For that purpose, adjusted partial correlations and stepwise multivariable linear regression analysis were performed. No correlation was found between TBS and disease severity. TBS was negatively associated with weight, BMI, waist perimeter, fat percentage, and systolic and diastolic blood pressure before and after adalimumab. After 6months of therapy, a negative correlation between TBS and insulin resistance (?? = 0.02) and leptin (?? = 0.01) and a positive correlationwith adiponectin were found (?? = 0.01).The best set of predictors for TBS values at baseline were female sex (?? = 0.015), age (?? = 0.05), and BMI (?? = 0.001). The best set of predictors for TBS following 6 months of biologic therapy were age (?? = 0.001), BMI (?? < 0.0001), and serumadiponectin levels (?? = 0.027). In conclusion, in nondiabetic patients withmoderate-to-severe psoriasis, TBS correlates with metabolic syndrome features and inflammation.This association is still present after 6 months of adalimumab therapy. Moreover, serum adiponectin levels seem to be an independent variable related to TBS values, after adalimumab therapy

Characterization of Fusarium species associated with rotting of corn root in Guanajuato, Mexico

"En el maíz Fusarium spp., ocasiona marchitez desde plántulas hasta planta adulta, causando generalmente pudriciones en los órganos vegetativos, como hojas, tallo y raíz. En el presente estudio se caracterizó la diversidad de especies del género Fusarium asociadas a la pudrición del tallo de maíz, en parcelas del estado de Guanajuato, y se realizaron pruebas de patogenicidad con las especies identificadas. Durante el 2006 se colectaron, en 15 municipios, plantas con daño evidente causado por éste patógeno. En 2009, se identificaron las especies presentes mediante pruebas microbiológicas y se evaluó su patogenicidad al inocularlas en trece accesiones raciales de maíz. Los resultados indican la presencia de F. subglutinans, F. verticillioides, F. heterosporum, F. esquiseti, F. proliferatum y F. reticulatum, en donde F. subglutinans fue la especie más abundante. En cuanto a patogenicidad, F. verticillioides y F. subglutinans fueron las especies más patogénicas en las razas de maíz. La raza de maíz más tolerante fue la raza Tuxpeño y la más susceptible fue Zapalote Chico.""The negative effects revealed in corn, such as seedlings decay to damage on the mature plant, are caused by Fusarium spp., usually causing decay on the plant organs, for instance leaves, stem and root. The present study characterized the diversity of Fusarium species associated with rotting of corn stalk in plots from the state of Guanajuato; pathogenicity tests were performed with the identified species. Plants with an evident damage caused by this pathogen were collected from 15 municipalities during 2006. The species identified in 2009, by means of microbiological tests and their pathogenicity, became evaluated as they were inoculated into thirteen race of maize accessions. The presence of F. subglutinans, F. verticillioides, F. heterosporum, F. esquiseti, F. proliferatum and F. reticulatum is revealed, being F. subglutinans the most abundant species. Concerning pathogenicity, F. verticillioides and F. subglutinans were the most pathogenic races of maize. The most tolerant race of maize was the Tuxpeño breed, and the most susceptible was the Zapalote Chico.

Antibody conversion rates to SARS-CoV-2 in saliva from children attending summer schools in Barcelona, Spain.

Background: Surveillance tools to estimate viral transmission dynamics in young populations are essential to guide recommendations for school opening and management during viral epidemics. Ideally, sensitive techniques are required to detect low viral load exposures among asymptomatic children. We aimed to estimate SARS-CoV-2 infection rates in children and adult populations in a school-like environment during the initial COVID-19 pandemic waves using an antibody-based field-deployable and non-invasive approach. Methods: Saliva antibody conversion defined as ≥ 4-fold increase in IgM, IgA, and/or IgG levels to five SARS-CoV-2 antigens including spike and nucleocapsid constructs was evaluated in 1509 children and 396 adults by high-throughput Luminex assays in samples collected weekly in 22 summer schools and 2 pre-schools in 27 venues in Barcelona, Spain, from June 29th to July 31st, 2020. Results: Saliva antibody conversion between two visits over a 5-week period was 3.22% (49/1518) or 2.36% if accounting for potentially cross-reactive antibodies, six times higher than the cumulative infection rate (0.53%) assessed by weekly saliva RT-PCR screening. IgG conversion was higher in adults (2.94%, 11/374) than children (1.31%, 15/1144) (p=0.035), IgG and IgA levels moderately increased with age, and antibodies were higher in females. Most antibody converters increased both IgG and IgA antibodies but some augmented either IgG or IgA, with a faster decay over time for IgA than IgG. Nucleocapsid rather than spike was the main antigen target. Anti-spike antibodies were significantly higher in individuals not reporting symptoms than symptomatic individuals, suggesting a protective role against COVID-19. Conclusion: Saliva antibody profiling including three isotypes and multiplexing antigens is a useful and user-friendlier tool for screening pediatric populations to detect low viral load exposures among children, particularly while they are not vaccinated and vulnerable to highly contagious variants, and to recommend public health policies during pandemics

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

The scope of language contact as a constraint factor in language change: The periphrasis haber de plus infinitive in a corpus of language immediacy in modern Spanish

In this work an empirical study grounded in the principles and methods of the comparative variationist framework is conducted to measure the scope of language contact as a factor constraining some potentially diverging uses of a Spanish verbal periphrasis that has undergone a sharp decline over the last century (haber de plus infinitive). The analysis is based on three independent samples of text that correspond to three dialectal areas of peninsular Spanish (monolingual zones, Catalan-speaking linguistic territories and the north-western linguistic area). These samples, extracted from a corpus made up of texts of communicative immediacy from the 19th and the first half of the 20th centuries, confirm the existence of a certain linguistic convergence in the expressive habits of the speakers in the bilingual communities. In each region, however, the outcomes are different, due to parallel differences in the structural position of the periphrasis in each language. However, a thorough analysis of the variable context that surrounds the periphrasis shows that the observed differences do not affect the essence of the underlying grammar of this variant, whose decline (which favours tener que plus infinitive and becomes faster as the 20th century advances) is constrained by identical linguistic and extralinguistic conditioning factors in all the dialectal areas

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

First Latin American clinical practice guidelines for the treatment of systemic lupus erythematosus: Latin American Group for the Study of Lupus (GLADEL, Grupo Latino Americano de Estudio del Lupus)-Pan-American League of Associations of Rheumatology (PANLAR)

Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an 'overarching' treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings.Fil: Pons Estel, Bernardo A..
