Niveles de vida y diferencias rural-urbana de la estatura en los inicios del crecimiento económico español

This paper examines the urban-rural differences of the height during the early stages of modern economic growth and industrialization in Spain. Its aim is to explore the extent of the urban penalty, and the changes of biological welfare in the cities and villages, in the rural and urban areas. We use height data of military recruitment records between 1857 and 1936, that provide information on the health and net nutrition of cohorts 1837-1915. We note that previous studies reported higher penalty in rural areas than in cities, and that the height deteriorated in the most industrialized cities due to unhealthy environments, child labor and spread of infections. The new data shows that in some rural areas had better nutritional status that in urban areas with better care resources, so the rural-urban gap was more diverse than we thought, not only by environmental factors but institutions. Data suggests more research on height by social classes in the diverse Spanish geography.Este trabajo examina las diferencias urbano-rurales de la estatura durante las primeras fases de la industrialización española. Su objetivo es explorar la dimensión de la urban penalty y los cambios del bienestar biológico en las ciudades frente al mundo rural. Usamos como principal fuente de datos las tallas de los reclutamientos militares entre 1857 y 1936, que nos informan sobre la salud y la nutrición neta en las cohortes de 1837 a 1915. Señala que los estudios previos registraron una mayor penalización en las zonas rurales que en las ciudades y que la talla se deterioró en las ciudades más industrializadas como consecuencia de ambientes insalubres, del abultado empleo infantil y alta incidencia de las infecciones. Los nuevos datos demuestran que en ciertos ámbitos rurales había un mejor estado nutricional que en algunos centros urbanos bien provistos de recursos asistenciales; por tanto, la brecha rural-urbana de la estatura fue más diversa de lo que pensábamos, por factores no sólo ambientales sino institucionales. Se sugiere ampliar la investigación sobre la geografía de la estatura y analizarla por clases sociales

Implementation and validation of an economic module for the epidemiological model Be-FAST to predict the costs generated by livestock diseases epidemics. Application to the Classical Swine Fever case in Spain.

Classical Swine Fever (CSF) is one of the most harmful livestock di-seases for the economy of the swine sector worldwide. Specifically in Spain, the costs in the two last CSF outbreaks (1997 and 2001) have been estimated above 108 million euros. In this work, we aim to evaluate the economic impact of important livestock disease epidemics, and particularly the CSF in Spain. This study starts with a preliminary classification of the costs associated with CSF epidemics. In order to estimate the expected costs of a given epidemic in a considered area, a new economic module has been integrated into the epidemiological model Be-FAST, a time-spatial stochastic spread mathematical model for studying the transmission of diseases within and between farms. The input data for economic parameters have been obtained from entities related with the swine industry in Spain. The new Be-FAST module is tested by comparing the results obtained with historical data from CSF epidemics in Spain. The outcomes show that severe CSF epidemics also have a strong economic impact with around 80% of the costs related to animal culling, while costs associated with control measures are directly associated with the number of infected farms and the duration of the epidemic. The results presented in this work are expected to provide valuable information to decision makers, including animal health officials and insurance companies, and can be extended to other livestock diseases or used to predict the economic impact of future outbreaks

γ-Aminobutyric acid treatments of pomegranate trees increase crop yield and fruit quality at harvest

γ-Aminobutyric (GABA) is a non-protein amino acid that has been reported to affect different plant developmental processes, including delay of fruit senescence and maintenance of quality when applied as postharvest treatment. In this experiment, GABA treatments (10, 50 and 100 mM) were applied by foliar spray to ‘Mollar de Elche’ pomegranate trees at three key points of fruit development. Results showed that GABA treatments increased crop yield in a dose-dependent way, this effect being due to a higher number of fruit harvested per tree. In addition, GABA treatments led to a deeper red colour of pomegranate skin and arils, the highest effects being observed for 100 mM dose. Total phenolic and total anthocyanin concentrations were also increased by GABA treatment, while other quality parameters such as total soluble solids, total acidity or firmness were not affected by treatments. Then, GABA preharvest treatment, applied at 100 mM, could be a useful tool to increase the economic profit of pomegranate crop, since higher yield and fruit with higher colour were obtained, which is an important quality parameter for this cultivar. In addition, aril total phenolics and anthocyanin content were increased, which would lead to enhance the antioxidant properties and health benefits for consumers

Reconstructing the impact of human activities in a NW Iberian Roman mining landscape for the last 2500 years

This article was made available through the Brunel Open Access Publishing Fund.Little is known about the impact of human activities during Roman times on NW Iberian mining landscapes beyond the geomorphological transformations brought about by the use of hydraulic power for gold extraction. We present the high-resolution pollen record of La Molina mire, located in an area intensely used for gold mining (Asturias, NW Spain), combined with other proxy data from the same peat core to identify different human activities, evaluate the strategies followed for the management of the resources and describe the landscape response to human disturbances. We reconstructed the timing and synchronicity of landscape changes of varying intensity and form occurred before, during and after Roman times. An open landscape was prevalent during the local Late Iron Age, a period of relatively environmental stability. During the Early Roman Empire more significant vegetation shifts took place, reflected by changes in both forest (Corylus and Quercus) and heathland cover, as mining/metallurgy peaked and grazing and cultivation increased. In the Late Roman Empire, the influence of mining/metallurgy on landscape change started to disappear. This decoupling was further consolidated in the Germanic period (i.e., Visigothic and Sueve domination of the region), with a sharp decrease in mining/metallurgy but continued grazing. Although human impact was intense in some periods, mostly during the Early Roman Empire, forest regeneration occurred afterwards: clearances were local and short-lived. However, the Roman mining landscape turned into an agrarian one at the onset of the Middle Ages, characterized by a profound deforestation at a regional level due to a myriad of human activities that resulted in an irreversible openness of the landscape. © 2014 The Authors

Effect of the aniline fragment in Pt(II) and Pt(IV) complexes as anti-proliferative agents. Standard reduction potential as a more reliable parameter for Pt(IV) compounds than peak reduction potential

The problems of resistance and side effects associated with cisplatin and other chemotherapeutic drugs have boosted research aimed at finding new compounds with improved properties. The use of platinum(IV) prodrugs is one alternative, although there is some controversy regarding the predictive ability of the peak reduction potentials. In the work described here a series of fourteen chloride Pt(II) and Pt(IV) compounds was synthesised and fully characterised. The compounds contain different bidentate arylazole heterocyclic ligands. Their cytotoxic properties against human lung carcinoma (A549), human breast carcinoma (MCF7) and human colon carcinoma (HCT116 and HT29) cell lines were studied. A clear relationship between the type of ligand and the anti-proliferative properties was found, with the best results obtained for the Pt(II) compound that contains an aniline fragment, (13), thus evidencing a positive effect of the NH2 group. Stability and aquation studies in DMSO, DMF and DMSO/water mixtures were carried out on the active complexes and an in-depth analysis of the two aquation processes, including DFT analysis, of 13 was undertaken. It was verified that DNA was the target and that cell death occurred by apoptosis in the case of 13. Furthermore, the cytotoxic derivatives did not exhibit haemolytic activity. The reduction of the Pt(IV) compounds whose Pt(II) congeners were active was studied by several techniques. It was concluded that the peak reduction potential was not useful to predict the ability for reduction. However, a correlation between the cytotoxic activity and the standard reduction potential was found.This work has been funded by the Spanish Ministerio de Ciencia, Innovación y Universidades (MCIU), Agencia Estatal de Investigación (AEI) and Fondo Europeo de Desarrollo Regional (FEDER) (RTI2018-100709-B-C21 to BRM, RTI2018-100709-B-C22 to AM, RTI2018-094093-B-I00 to RSP), Junta de Comunidades de Castilla-La Mancha-FEDER (JCCM) (grant SBPLY/19/180501/000260 to BRM), Ministerio de Economía y Competitividad (Project PID2019-104381GB-I00 to GC), Fundación Leticia Castillejo Castillo to MJRH, Junta de Castilla y León, Consejería de Educación y Cultura y Fondo Social Europeo (Projects BU263P18 and BU087G19 to JVC) as well as UCLM-FEDER (grants 2019-GRIN-27183 and 2019-GRIN-27209 to BRM) and University of Girona (MPCUdG2016/076 to AM)

Toward the Discovery of Biological Functions Associated with the Mechanosensor Mtl1p of \u3ci\u3eSaccharomyces cerevisiae\u3c/i\u3e via Integrative Multi-OMICs Analysis

Functional analysis of the Mtl1 protein in Saccharomyces cerevisiae has revealed that this transmembrane sensor endows yeast cells with resistance to oxidative stress through a signaling mechanism called the cell wall integrity pathway (CWI). We observed upregulation of multiple heat shock proteins (HSPs), proteins associated with the formation of stress granules, and the phosphatase subunit of trehalose 6-phosphate synthase which suggests that mtl1Δ strains undergo intrinsic activation of a non-lethal heat stress response. Furthermore, quantitative global proteomic analysis conducted on TMT-labeled proteins combined with metabolome analysis revealed that mtl1Δ strains exhibit decreased levels of metabolites of carboxylic acid metabolism, decreased expression of anabolic enzymes and increased expression of catabolic enzymes involved in the metabolism of amino acids, with enhanced expression of mitochondrial respirasome proteins. These observations support the idea that Mtl1 protein controls the suppression of a non-lethal heat stress response under normal conditions while it plays an important role in metabolic regulatory mechanisms linked to TORC1 signaling that are required to maintain cellular homeostasis and optimal mitochondrial function

Indoor air pollution caused by cigarette smoke in public places in Portugal

OBJETIVO: Poucos têm sido os estudos para conhecer o grau de poluição pelo fumo do tabaco a que estão sujeitas as pessoas em vários lugares públicos e privados. O objectivo do estudo foi quantificar o nível de poluição do ar provocada pelo fumo do cigarro em locais de trabalho e de lazer. MÉTODOS: O estudo foi realizado no concelho de Braga, Portugal, em 2005. A medição dos teores de nicotina no ar interior foi realizada com monitores passivos contendo um filtro de 37 mm de diâmetro tratado com bissulfato sódico no seu interior. Os monitores foram colocados em lugares públicos, de trabalho e de lazer, pré-definidos. Para cada um dos locais, calculou-se a mediana da nicotina. RESULTADOS: A presença de nicotina foi detectada em 85% das amostras. Foram encontrados valores elevados de contaminação do ar nas discotecas, com mediana de 82,26 µg/m3, variando entre os 5,79 e os 106,31 µg/m3.Os locais de trabalho da administração pública e da universidade apresentaram os valores mais baixos de nicotina. CONCLUSÕES: Os dados confirmam a necessidade de reforçar a implemen-tação e sobretudo, o cumprimento de políticas sem fumo nos locais de trabalho e de lazer, em benefício da saúde dos trabalhadores e como medida reforçadora de um ambiente que facilite aos fumadores o abandono do fumo do tabaco.OBJECTIVE: There have been few studies investigating the level of cigarette smoke pollution to which people in several public and private places are exposed. The purpose of this study was to quantify the level of air pollution produced by cigarette smoking in workplaces and leisure settings. METHODS: The study was carried out in Braga, Portugal, in 2005. Nicotine content in indoor air was measured using passive monitors containing a 37-mm diameter filter inside treated with sodium bisulphate. The monitors were installed in predefined public workplaces and leisure settings. Median nicotine content was estimated for each place studied. RESULTS: Nicotine was detected in 85% of the samples. Extremely high air contamination levels were found in discos with a median of 82.26 µg/m3, ranging between 5.79 and 106.31 µg/m3. Workplaces of public administration and university buildings showed the lowest nicotine content. CONCLUSIONS: The study findings confirm the need to promote the implementation of smoke-free policies in workplaces and leisure settings to protect workers' health and as a reinforcing measure of an environment which facilitates smokers to quit smoking.info:eu-repo/semantics/publishedVersio

High efficacy of Sofosbuvir plus Simeprevir in a large cohort of Spanish cirrhotic patients infected with genotypes 1 and 4

[Abstract] Background and Aims. Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and real‐world clinical practice, showed high rates of sustained virological response (SVR) in non‐cirrhotic genotype (GT)‐1 and GT‐4 patients. These results were slightly lower in cirrhotic patients. We investigated real‐life effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients. Methods. This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCV‐GT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between January‐2014 and December‐2015. Demographic, clinical, virological and safety data were analysed. Results. Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELD≥10) or portal hypertension (platelet count≤100×109/L, transient elastography≥21 Kpa) showed significantly lower SVR rates (84.4%‐91.9%) than patients with less advanced liver disease (93.8%‐95.9%, P<.01 in all cases). In the multivariate analysis, the use of RBV, female gender, baseline albumin≥35 g/L, MELD<10 and lack of exposure to a triple therapy regimen were independent predictors of SVR (P<.05). Serious adverse events (SAEs) and SAE‐associated discontinuation events occurred in 5.9% and 2.6%. Conclusions. In this large cohort of cirrhotic patients managed in the real‐world setting in Spain, SOF/SMV±RBV yielded to excellent SVR rates, especially in patients with compensated liver cirrhosis. In addition, this combination showed to be safe, with low rates of SAEs and early discontinuations.Instituto de Salud Carlos III; PI15/0015
