Unamuno, intelectual público en la encrucijada de la guerra española. La agonía de la crítica tradicional
Authors: Cuesta Fernández Raimundo 
Published: June 2024

Unamuno, el primer intelectual moderno en España, representa una forma profética y contradictoria de hacer política, sobre todo a partir de la instauración en España de la República y más aún tras la guerra civil provocada por el golpe de Estado del 18 de julio de 1936. En este artículo se analiza su singular figura pública, su pasado liberal, su inicial adhesión al régimen de Franco y su rebelde actitud el 12 de octubre de 1936 en el Paraninfo de la Universidad de Salamanca frente a las autoridades franquistas. Se describe la actual polémica historiográfica sobre el alcance de sus actitudes este día, repasando las últimas novedades bibliográficas y cinematográficas. Y se defiende la tesis de que su comportamiento, más allá de la dimensión paradójica, expresa la agonía del intelectual tradicional que habla en nombre de valores universales y la emergencia de un nuevo tipo de intelectual de militancia partidista que a su vez hoy está en retirada.
Sobre ruidos y furias: un recorrido por la violencia del Novecientos europeo
Authors: Hernández Sánchez Fernando 
Published: June 2024

La violencia es un fenómeno repudiado hoy en día por la cultura cívica y política de los países avanzados. Pero no siempre, ni hace mucho, fue así: durante buena parte del siglo XX y en casi todos los puntos geográficos del viejo continente, la violencia protagonizó las relaciones entre estados, entre naciones, entre grupos étnicos y entre clases sociales. La violencia, esa partera de la Historia en frase apócrifa atribuida a Karl Marx, se apoderó de las pasiones humanas y definió la forma en que se debían resolver las pugnas de hegemonía entre los distinto modelos de sistema —capitalismo, comunismo—, de gobierno —democracia, dictaduras— y de convivencia —nacionalismo, pluralismo—. Es al estudio de este hilo conductor de la historia reciente al que Julián Casanova ha dedicado su último ensayo

Published: June 2024

In a jujube orchard, cropping withgrass may influence bacterial diversity and ecological networks due to changes of physicochemical properties in soil, which has a serious effect on the stability of soil ecosystems. The aim of this study was to analyze the effects of different cultivation methods (CK: cleaning tillage; NG: cropping with native grass; VV: cropping with Vicia villosa) on the soil’s bacterial structure and its co-occurrence network in a jujube orchard. The results showed that the highest moisture content, total nitrogen, and organic matter in the rhizosphere soil of a jujube orchard was found in the VV group. The soil’s moisture content, total nitrogen, and organic matter in the VV group were 2.66%, 0.87 g kg−1, and 5.55 mg kg−1 higher than that found in the CK group. Compared to the CK group, the number of unique species in the rhizosphere soil in the NG and the VV groups increased by 7.33% and 21.44%. The PICRUSt and FAPROTAX analysis showed that sown grass had a greater influence on the ecological function of the soil’s bacteria. Cropping with Vicia villosa and native grass significantly increased aerobic chemoheterotrophy, nitrogen respiration, nitrate reduction related to biochemical cycles, and the relative abundance of genes related to carbohydrate metabolism and the biodegradation of xenobiotics. The bacterial network complexity in the NG group was higher than that in the CK and VV groups and was greatest in the hub nodes (OTU42, Bacteroidota; OTU541, Nitrospiraceae). In this study, the ecological benefit seen in the soil’s microbial function provides support to the theory that cropping with grass (Vicia villosa) increases the sustainable development of a jujube orchard.
huella del carbón.

Published: June 2024

Los paisajes posindustriales legados por las industrias de los siglos XIX y XX en Chile son vestigios materiales y simbólicos del auge del desarrollo económico y social del país, y el resultado de procesos de transformación territorial, social y cultural. En estos paisajes se perciben las huellas antrópicas sobre el territorio, adquiriendo valores de paisaje cultural al haber sido parte fundamental en la construcción de la identidad local.
La zona del Golfo de Arauco se configuró como el principal centro de desarrollo de la minería del carbón, dando lugar al crecimiento de ciudades que construyeron su identidad en base a la cultura minera. Con el cierre de industrias durante el siglo XX, se configuró un cementerio de ciudades ruinas, y Lota, corazón de la industria, cayó en un proceso de abandono, siendo actualmente uno de los principales ejemplos nacionales de un paisaje posindustrial degradado y de la pérdida de la memoria asociada a la historia industrial.
El presente artículo examina el mayor sitio posindustrial de Lota: el sector de Chambeque. Para ello se expone una metodología de análisis paisajístico que incluyó mapeos, revisión bibliográfica histórica y levantamiento fotográfico. Esto permitió analizar los valores contenidos en los paisajes posindustriales con miras al rescate del patrimonio y memoria de la ciudad, abriendo el debate sobre su abordaje y relevancia en el panorama actual a nivel nacional. A partir de esto se plantea la posibilidad de intervención por medio de un proyecto de arquitectura del paisaje basado en estrategias que permiten la conservación y puesta en valor de un sitio posindustrial, apuntando a objetivos como la conservación de ruinas, la remediación ambiental y la reincorporación del sitio a la dinámica urbana.

Authors: Habbal Rachida , Ouarrak Saadia , Dehbi Hind 
Published: June 2024

The cardio-oncology as a field has been expanded by the rapid development of innovative cancer therapies. While these treatments had significantly improved the overall survival rates for cancer patients, they also carried the risk of cardiovascular and metabolic toxicities. A comprehensive and accurate diagnosis of cancer was paramount to initiate appropriate and effective treatment strategies. It was essential to recognize that each type of cancer presents unique characteristics and complexities, necessitating personalized treatment approaches tailored to individual patients. These treatment regimens often encompassed a combination of modalities such as surgery, radiotherapy, systemic therapy, including chemotherapy, antineoplastic hormonal agents, targeted therapies, and supportive care interventions. By implementing a tailored treatment plan based on the specific nature of the cancer, healthcare professionals might optimize therapeutic outcomes while minimizing adverse effects, ultimately improving the overall prognosis and quality of life for cancer patients. The concise review aims to underscore the effects of cancer and its treatments on cardiovascular health, drawing insights from prior research. By synthesizing findings from existing studies, we aim to elucidate the intricate relationship between cancer therapies and cardiovascular outcomes. Consequently, there is a pressing need for an updated summary to inform contemporary clinical practice, ensuring that healthcare professionals are equipped with the latest knowledge to provide optimal care for cancer patients while safeguarding their cardiovascular well-being.
On the Mechanism of Asymmetric Epoxidation of Enones Catalyzed by α,α‐L‐Diarylprolinols: A Theoretical Insight
Authors: Capobianco Amedeo , Russo Alessio , Lattanzi Alessandra , Peluso Andrea 
Published: October 2012

AbstractThe mechanism of the asymmetric epoxidation of enones with tert‐butyl hydroperoxide promoted by α,α‐L‐diarylprolinols has been studied by second order Møller–Plesset perturbation theory (MP2) and density functional theory (DFT) computations. The non‐covalent activation of the reactants, through an effective network of hydrogen bonding interactions, initially hypothesized on the basis of the available experimental data, is shown to constitute an energetically viable pathway. According to the non‐covalent route, the reaction follows a two‐step nucleophilic epoxidation mechanism, with the first oxa‐Michael addition being the rate‐ and stereoselectivity‐determining step. Formation of the (2R,3S)‐enantiomer of the epoxide derived from trans‐chalcone is predicted to be energetically favoured, in agreement with the experimental findings.

Published: October 2012

AbstractUsing the palladium/2‐(dicyclohexylphosphino)‐2′,6′‐di(isopropoxy)biphenyl (RuPhos) catalyst, aryl halides and tricyclohexylsilyl selenol can be efficiently coupled to the respective aryl tricyclohexylsilyl selenides. These can be transformed in the same reaction vessel to the corresponding selenoacetates, permitting a straightforward access to a range of molecules potentially useful for materials science applications.
A highly sensitive immunoassay for interleukin‐6 in dried blood spots
Authors: Miller Elizabeth M. , Mcdade Thomas W. 
Published: October 2012

AbstractObjective:Interleukin‐6 (IL‐6) is a pro‐inflammatory cytokine that is associated with the production of C‐reactive protein, the acute phase response, and chronic low‐grade inflammation. In this report, we describe and validate a highly sensitive enzyme‐linked immunosorbent assay (ELISA) for quantifying IL‐6 at low concentrations in samples of capillary whole blood collected from a simple finger stick and dried on filter paper (dried blood spots, DBS).Methods:A commercially available ELISA for IL‐6 was modified to develop a protocol for the quantification of IL‐6 in DBS samples. Procedures for sample elution and incubation were optimized for precision, reliability, accuracy, and lower limit of detection using small volumes of DBS. A set of 46 matched serum/DBS samples were used to evaluate agreement between serum and DBS results.Results:The protocol demonstrated acceptable levels of precision, reliability, accuracy, and agreement with serum‐based results. The lower limit of detection was sufficiently low to measure levels of IL‐6 associated with both chronic, low‐grade inflammation, and acute increases in inflammatory activity.Conclusions:This protocol adds to the growing panel of analytes validated for quantification in DBS samples and should facilitate future research on the causes and consequences of inflammation in diverse non‐clinical settings.

Published: October 2012

AbstractWe present growth curves of 1,726 Turkish children with Down syndrome (DS) between 0 and 18 years of age and investigate the factors that affect growth including congenital heart disease (CHD) and hypothyroidism. Longitudinal measurements of height, weight, and head circumference (HC) were assessed and accompanying major malformations were recorded. Growth curves were monitored using Cole's LMS method. The mean birth length was reduced by −0.5 standard deviation (SD) for Turkish standards in both boys and girls. Pubertal growth spurt of the girls with DS started 1 year earlier, their puberty duration was short and pubertal annual growth rate was inadequate, and as a result the final height was −3.06 SD for Turkish standards. Although the age at onset of pubertal growth spurt and puberty duration of the boys were similar to normal population, their pubertal annual growth rate was inadequate; thus the final height was −2.56 SD for Turkish standards. The final weight values were similar to normal population. The mean HC values of DS children were corresponded to −0.9 SD for Turkish standards at birth; however after 6 months values were below −2 SD. The final HC values were −1.02 SD for boys and −2.21 SD for girls for Turkish standards. We observed that weight was decreased in DS children with severe CHD during first 4 years of life. However, there is no statistically significant difference in values of height and head circumference between patients with or without severe CHD group. In addition, hypothyroidism had no effect on growth in DS patients. © 2012 Wiley Periodicals, Inc.

AbstractAs an infectious disease, tuberculosis (TB) is one of the major causes of death worldwide. Paleopathological and paleomicrobiological studies indicate a long standing association of the causative agent Mycobacterium tuberculosis and its human host. Since the occurrence and the epidemic spread of this pathogen seem to be closely linked to social and biological factors, it is of particular interest to understand better the role of TB during periods of social and nutritional change such as the Neolithic. In this study, 118 individuals from three sites in Saxony‐Anhalt (Germany) dating to the Linear Pottery Culture (5400–4800 BC) were examined macroscopically to identify TB related bone lesions. In two individuals, Pott's disease was detected. In addition, periosteal reactions of varying degrees and frequency were observed mainly along the neck of the ribs in 6.5% (2/31) of subadults and 35.1% (20/57) of adults, with one site standing out markedly. Rib lesions, however, are not specific indicators of TB as they can also be caused by other diseases; so additional investigations were undertaken using histology and micro‐CT scans to say more about the disease process. Supplementary molecular analyses indicate the presence of pathogens belonging to the Mycobacterium tuberculosis complex in individuals of all sites. Furthermore, we discuss the occurrence and spread of TB during the Neolithic with regard to nutritional aspects and possible risks of infection. The data presented provide important insights into the health status of Early Neolithic populations in Central Germany. Am J Phys Anthropol, 2012. © 2012 Wiley Periodicals, Inc.
The diet‐body offset in human nitrogen isotopic values: A controlled dietary study
Authors: O'Connell T.C. , Kneale C.J. , Tasevska N. , Kuhnle G.G.C. 
Published: October 2012

AbstractThe “trophic level enrichment” between diet and body results in an overall increase in nitrogen isotopic values as the food chain is ascended. Quantifying the diet–body Δ15N spacing has proved difficult, particularly for humans. The value is usually assumed to be +3–5‰ in the archaeological literature. We report here the first (to our knowledge) data from humans on isotopically known diets, comparing dietary intake and a body tissue sample, that of red blood cells. Samples were taken from 11 subjects on controlled diets for a 30‐day period, where the controlled diets were designed to match each individual's habitual diet, thus reducing problems with short‐term changes in diet causing isotopic changes in the body pool. The Δ15Ndiet‐RBCwas measured as +3.5‰. Using measured offsets from other studies, we estimate the human Δ15Ndiet‐keratinas +5.0–5.3‰, which is in good agreement with values derived from the two other studies using individual diet records. We also estimate a value for Δ15Ndiet‐collagenof ≈6‰, again in combination with measured offsets from other studies. This value is larger than usually assumed in palaeodietary studies, which suggests that the proportion of animal protein in prehistoric human diet may have often been overestimated in isotopic studies of palaeodiet.

Published: October 2012

AbstractThis set of cross‐sectional and longitudinal data from children and young adults in certain Bougainville and Solomon Islands populations undergoing rapid modernization during the period 1966–1986 reveals very different responses to essentially the same stimuli—the introduction and widespread availability of western dietary items and reductions in habitual activity. Our analyses of over 2,000 children and young adults first measured in 1966–1972, with follow‐up surveys in 1968–1970 and 1985–1986, show changes in overweight/obesity in these communities have their onset around puberty, and are not related to differences in childhood growth stunting. The prevalence of overweight and obesity increased substantially during the period of this study among young adults, particularly women, and in groups with more Polynesian affinities, where the frequency of overweight (BMI ≥ 25) tripled over this 20‐year interval. However, the BMI of the more Papuan groups on Bougainville remained remarkably stable, even though they were close to the epicenter of modernization during this period, the Bougainville Copper Mine.

Enhanced cell viability via strain stimulus and fluid flow in magnetically actuated scaffolds
Authors: Mack Julia J. , Corrin Abigail A. , dos Santos e Lucato Sergio L. , Dunn James C.Y. , Wu Benjamin W. , Cox Brian N. 
Published: October 2012

AbstractA novel magnetically actuated scaffold was used to explore the effects of strain stimulus on the proliferation and spatial distribution of smooth muscle cells and improve cell viability in the scaffold interior by pumping nutrients throughout the structure. Magnetically actuable scaffolds were fabricated in a tube shape by winding electrospun sheets of a biodegradable polymer modified with magnetic Fe2O3 nanoparticles. Prior to rolling, the sheets were seeded with smooth muscle cells and wound into tubes with diameter 5.2 mm and wall thickness 0.2 mm. The tubular scaffolds were actuated by a magnetic field to induce a cyclic crimping deformation, which applies strain stimulus to the cells and pumps nutrient fluid through the porous tube walls. Comparison with non‐actuated controls shows that magnetic actuation increases the total cell count throughout the scaffold after 14 days of incubation. Furthermore, whereas cell density as a function of position through the tube wall thickness showed a minimum in the mid‐interior in the controls after 14 days due to cell starvation, the actuated scaffolds displayed a maximum cell density. Comparison of cell distributions with the expected spatial variations in strain amplitude and nutrient flux implies that both strain stimulus and nutrient pumping are significant factors in cell proliferation.
