From intestine transport to enzymatic regulation: The works of the Spanish biochemist Alberto Sols (1917–1989)

In this paper the scientific trajectory of Spanish influential biochemist Alberto Sols (1917–1989) is presented in comparative perspective. His social and academic environment, his research training under the Cori's in the US in the early 1950s and his works when coming back to Spain to develop his own scientific career are described in order to present the central argument of this paper on his path from physiological research to research on enzymatic regulation. Sols' main contributions were both scientific and academic. He and his collaborators not only contributed to biological knowledge on the biochemistry of metabolic regulation but to the active reception of biochemistry in the Spanish academia and to update of Spanish medical education.     

Constructed identities and Iberia

The category of Iberian identity includes national identities within Spain, Portugal and Latin America. The case of Spain and Spanish national identity has been particularly neglected in academic literature, although this situation has been changing since the mid-1990s, in comparison with analyses of alternative national identities within the Spanish state. This is related the discrediting of Spanish nationalism during the Francoist dictatorship later democratic devolution which encouraged an analogous diversification in the study of national identities within Spain. Since the asymmetric of Spain, Spanish interpretations of nationhood have reflected the premise of the 1978 Constitution that the nation's unity is complemented and strengthened by its national and regional diversity. Variety within broad category of Iberian identities is augmented by the incidence of labour migration into Spain and Portugal and development of popular culture, this case music, in Latin America and specifically Colombia.     

Determination of COD,BOD, and suspended solids loads during combined sewer overflow (CSO) events in some combined catchments in Spain

The main topic of the research project presented here in part is the determination of pollutant loads during combined sewer overflow events in several experimental catchments in Spain that were determined to obtain a pollution pattern which may be applied to other catchments in Spain or an order of magnitude of pollution loads in Spanish catchments. The existence or non-existence of a first-flush is also examined. Five catchments were monitored in five Spanish cities, and both hydraulic parameters and pollutant amounts were measured in dry conditions and during rainfall events. From the data obtained, some parameters were extracted for each catchment and an order of magnitude of the pollution amounts was proposed for Spanish catchments, in terms of event mean concentration (EMC) and maximum concentrations, since the moderate differences between catchments permit an estimation of a mean value.     

The mortality of two groups of infants in Spanish rural region

In this study the structure of the mortality of two groups of infants settled in the same environmental context is analysed: the comarca (a typical Spanish sub-division of territory) of La Cabrera (province of León, Spain) between the years 1880 and 1932. In this geographical region of the northwest of Spain two communities of infants from different origins are found in this time period. On the one hand, an autochthonous infant population from the births of the legitimately constituted families settled in this territory. On the other, an infant population represented by a group of children who were abandoned in a foundling hospital situated in a nearby city (Ponferrada) and who were sent to this rural "comarca" to be breast-fed by wet-nurses being paid certain quantities of money. The mortality rates and the seasonality of the deaths have been analysed for both the autochthonous and non-autochthonous children. Thus we have been able to test whether differences in the structure of mortality exist. Throughout the study, the possibility that these differences in mortality could be attributed to discriminative cultural factors, expressed through preferential care and/or attention and which show in the different models of infant mortality, is considered.     

Guía sobre el manejo de desfibriladores automáticos implantables al final de la vida

This article is a joint document of the Spanish Society of Geriatrics and Gerontology, the Spanish Society of Palliative Care and the Section of Geriatric Cardiology of the Spanish Society of Cardiology. Its aim is to address the huge gap that exists in Spain with regard to the management of implantable cardioverter defibrillators (ICDs) in the final stages of life. It is increasingly common to find patients carrying these devices that are in the terminal stage of an advanced disease. This occurs in patients with advanced heart disease and subsequent heart failure refractory to treatment but also in a patient with an ICD who develops cancer disease, organ failure or other neurodegenerative diseases with poor short-term prognosis. The vast majority of these patients are over 65, so the paper focuses particularly on the elderly who are in this situation, but the decision-making process is similar in younger patients with ICDs who are in the final phase of their life.     

Allelic and Genotypic Composition of Ancestral Spanish and Colonial Californian Gene Pools of Avena Barbata: Evolutionary Implications

Spanish explorers and colonists inadvertently started a massive experiment in evolutionary genetics when they accidentally introduced Avena barbata to California from Spain during the seventeenth and eighteenth centuries. Assays of the Spanish and Californian gene pools of this species for 15 loci show that the present day Spanish gene pool, particularly that of Southwestern Spain, is identical or virtually identical to that of California for five loci and closely similar for nine loci. Despite their similar allelic and single-locus genotypic compositions, the present-day Spanish and Californian gene pools are differently structured on a multilocus genetic basis. Evolutionary implications of these results are discussed.     

Setting “Spanish legacies” into further context: some findings and thoughts from CILS4EU

This contribution compares some major findings of “Spanish Legacies” to findings from the CILS4EU study that has been conducted in four other European countries. Despite the differences in the immigration history and the composition of the immigrant youth, basic results of psychosocial adaptation are surprisingly similar for England, Germany, the Netherlands, and Sweden. This confirms the mostly optimistic picture of the future of the second generation in Europe as drawn for Spain. In a sense, the similarities suggest that the role of the receiving context might be less important than is expected in overarching theoretical frameworks such as “segmented assimilation”. Some aspects of integration that are not covered in “Spanish Legacies” could raise more doubts on the smoothness of the adaptation processes for some immigrants groups.     

Report of an imported cutaneous disseminated case of paracoccidioidomycosis

Paracoccidioidomycosis is a chronic progressive infection. It affects mainly the elderly and it is geographically limited to certain areas of Latin America. In Europe it is considered a rare imported infection. Here we report a case of paracoccidioidomycosis that occurred in a 27-year-old Ecuadorian patient living in Spain initially misdiagnosed as blastomycosis. The typical multi-budding yeast cells of Paracoccidioides brasiliensis were observed in Grocott stained samples. This case should alert Spanish mycologists, clinicians and pathologists about the possibility of patients who have travelled or lived outside Spain may suffer paracoccidioidomycosis or other imported mycoses.     

Exploring diversity among Spanish strains of Erwinia amylovora and possible infection sources

AIMS: We have examined the intraspecific diversity of a collection of 63 Spanish strains of Erwinia amylovora, isolated from 1995 to 2001, to determine whether or not they could be grouped based on phenotypic or genotypic criteria and to investigate the sources of inoculum for fire blight dissemination in Spain. METHODS AND RESULTS: Several biochemical and molecular techniques, such as miniaturized API 20E, API 50CH, ATB G-5 and API-ZYM tests, BIOLOG metabolic fingerprinting, PCR ribotyping, pulsed-field gel electrophoresis (PFGE), minisatellite-primed PCR (MSP-PCR), random amplified polymorphic DNA (RAPD) analyses and AFLP were used. We report the first identification in Spain of the PFGE pattern Pt1, already described in other European countries, together with Pt3 and Pt4 patterns. Moreover, PFGE, together with MSP-PCR, RAPD analyses and AFLP are, until now, the only techniques that have provided information about the possible infection sources and relationships between the different foci in Spain, with AFLP being the most discriminative. CONCLUSIONS: These techniques have allowed grouping of Spanish strains by their geographical origin. SIGNIFICANCE AND IMPACT OF THE STUDY: Our results support the hypothesis that some fire blight outbreaks have been caused by the introduction in Spain of infected plant material, or other inoculum sources from different European countries.     

Differences in species composition and diversity among Mediterranean grasslands with different history – the case of California and Spain

Species composition and diversity were compared among twenty Mediterranean annual grasslands in northern and central California and central and southern Spain, encompassing climatic gradients and local site variation in topography and soils Geographic proximity was more important than environmental factors such as climate, topography and parent material in predicting the species composition of these grasslands, with Californian and Spanish grasslands sharing only 9% of the species and geographically separated regions within each country sharing only 20- 32% of the species This importance of geographic separation in predicting species composition suggests a strong role of dispersal limitation in determining current community composition Mean species diversity was lower in Californian than in Spanish grasslands and was negatively correlated with cover of annual grasses that tended to be greater in California than in Spain However, there were few differences in species diversity among sites within either country and patterns of species diversity were unrelated to soil fertility or productivity We suggest that current grazing regimes contribute to the greater abundance of grasses and lower species diversity of Californian than of Spanish grasslands The apparent importance of dispersal limitation and grazing m explaining differences in species composition and diversity between Californian and Spanish grasslands and within each country suggest that the structure of these grasslands has been and will continue to be sensitive to human influence     

What is Spanish nationalism today? From legitimacy crisis to unfulfilled renovation (1975–2000)

The article explores the different discourses on Spanish nationalism and 'patriotic affirmation' existing in contemporary Spain. Since the end of Francoism, Spanish nationalism has existed in a de-articulated and diffuse way, rather as a reaction against the challenge of stateless nationalisms than as a substantive doctrine. However, since the mid-1980s there has been a recovery of Spanish nationalist discourse, often labelled as 'Constitutional patriotism', whose main point is the insistence on History as the founding basis for the legitimation of the present Spanish polity, as well as the vindication of the 1978 Constitution as the end-point of decentralization.     

Spatio-temporal trends in gastric cancer mortality in Spain: 1975–2008

Aim of the study: There has been a downward trend in gastric cancer mortality worldwide. In Spain, a marked spatial aggregation of areas with excess mortality due to this cause has long been reported. This paper sought to analyse the evolution of gastric cancer mortality risk in Spanish provinces and explore the possible attenuation of the geographical pattern. Methods: We studied a series of gastric cancer mortality data by province, year of death, sex and age group using a conditional autoregressive (CAR) model that incorporated space, time and spatio-temporal interactions. Results: Gastric cancer mortality risk decreased in all Spanish provinces in both males and females. Overall, decreasing trends were more pronounced during the first years of the study period, largely due to a sharper fall in gastric cancer mortality risk among the older population. Recent decades have witnessed a slowing in the rate of decrease, especially among the younger age groups. In most areas, risk declined at a similar rate, thus serving to maintain interprovincial differences and the persistence of the geographical pattern, though with some differences. The north and northwest provinces were the areas with higher mortality risks in both sexes and age groups over the entire study period. Concluding statement: Despite the decline in gastric cancer mortality risk observed for the 50 Spanish provinces studied, geographical differences still persist in Spain, and the cluster of excess mortality in the north-west of the country remains in evidence.     

Challenges of Radiation Oncology in Spain Today

The increasing cost of health care delivery, coupled with reduced investments and budget cuts in European health care systems, has had a severe negative impact on health care delivery in Spain. This reduction in spending has had particularly negative effects on specialties that are heavily reliant on large capital investments to purchase the latest technologies needed to deliver optimal radiotherapy treatments. The Spanish Society of Radiation Oncology has been proactively working to mitigate the negative impact of budget cuts in Spain. In this paper, the authors describe a variety of solutions and proposals to overcome these challenges.     

Stock Transfers in Spanish Brown Trout Populations: A Long-term Assessment

Synopsis Stocking of fish from other populations has been commonly employed for enhancement of wild brown trout, Salmo trutta, populations in north Spain. Young hatchery reared brown trout of central European origin were introduced into some Asturian rivers every year since 1984. Based on variation at the isozyme locus LDH-C1* and at the microsatellite locus BFRO 002, two genetic markers race-specific in Salmo trutta, we detected introgression of foreign genomes into native gene pools in some Spanish trout populations where only pure native individuals were present 10 years ago. We strongly suggest development of alternative management policies for conservation of Spanish natural brown trout populations without endangering the traditional recreational fisheries. Jorge I. Izquierdo, Ana G. F. Castillo: These two authors contributed equally to the article.     

Undergraduate cancer education in Spain: The debate,the opportunities and the initiatives of the University Forum of the Spanish Society of Radiation Oncology (SEOR)

Most medical schools in Spain (80%) offer undergraduate training in oncology. This education is highly variable in terms of content (theory and practical training), number of credits, and the medical specialty and departmental affiliation of the professors. Much of this variability is due to university traditions in the configuration of credits and programmes, and also to the structure of the hospital-based practical training. Undergraduate medical students deserve a more coherent and modern approach to education with a strong emphasis on clinical practice. Oncology is an interdisciplinary science that requires the input of professors from multiple specialties to provide the primary body of knowledge and skills needed to obtain both a theoretical and clinical understanding of cancer. Clinical skills should be a key focus due to their importance in the current model of integrated medical management and care.Clinical radiation oncology is a traditional and comprehensive hospital-based platform for undergraduate education in oncology. In Spain, a significant number (n = 80) of radiation oncology specialists have a contractual relationship to teach university courses. Most Spanish universities (80%) have a radiation oncologist on staff, some of whom are department chairs and many others are full professors who have been hired and promoted under competitive conditions of evaluation as established by the National Agency for Quality Evaluation.The Spanish Society of Radiation Oncology (SEOR) has identified new opportunities to improve undergraduate education in oncology. In this article, we discuss proposals related to theoretical (20 items) and practical clinical training (9 items). We also describe the SEOR University Forum, which is an initiative to develop a strategic plan to implement and organize cancer education at the undergraduate level in an interdisciplinary teaching spirit and with a strong contribution from radiation oncologists.     

Distribution of MWG699 polymorphism in Spanish European barleys.

The STS marker MWG699/TaqI is closely linked to the vrs1 locus and has been proposed as a marker of domestication in barley. This study included 257 cultivated barleys of both two- and six-rowed varieties, mainly from the western Mediterranean region. These included many landraces from the Spanish barley core collection, Moroccan landraces, and a set of accessions from other European countries. Restriction analysis of amplified DNA revealed three alleles, as previously described. Most of the two-rowed entries had the same allele, type K. Six-rowed entries showed both types A and D. Indeed, type D was widespread among Spanish landraces and commercial varieties from central Europe. It was also found in some two-rowed landraces originating from Spain and Morocco. Barleys with the D haplotype were predominantly winter types, whereas the A haplotype was evenly distributed among spring and winter types. These results support the existence of two different genetic sources among six-rowed Spanish landraces.     

Productivity–diversity relationships for stream invertebrates differ geographically

More productive environments typically have more species, although the specific form of this relationship is unclear and can vary with spatial scale. This relationship has received little direct attention in lotic systems, and thus the nature of the relationship is unclear, as is any effect of spatial scale. We examined the link between stream primary productivity and macroinvertebrate diversity in Spain and New Zealand and hypothesized that macroinvertebrate diversity would increase log-linearly with increasing productivity in both regions. We sampled 24 streams in Cantabria, Spain, and 24 in the central North Island, New Zealand. Algal primary productivity was approximately three times higher in Spanish streams, but taxonomic richness of invertebrates did not differ between the regions. Richness and Shannon diversity only responded to productivity in the New Zealand streams, exhibiting the predicted log-linear increase. In the Spanish streams, only the total number of individuals increased with productivity. However, when plotted on the same axes, richness in the Spanish streams simply occurred on the linear portion of the graph to the right of the New Zealand streams. We speculate that productivity in the Spanish streams never became low enough to constrain diversity, but did in the New Zealand streams. Combining results from the two regions, there is no evidence of a decline in diversity with higher productivity.     

Discovery and study of dinosaurs from Spain: The contribution of Albert F. de Lapparent

Albert F. de Lapparent (1905–1975), the scion of a family of famous French geologists, was a dinosaur palaeontologist. He explored many territories in Europe, Saharan Africa and Asia in search of fossils. The studies he undertook in Spain, which resulted in a dozen publications between 1955 and 1969, are an important part of his research on dinosaurs. Lapparent et al. discovered about thirty dinosaur localities, mostly of Cretaceous age, in several Spanish provinces, including Albacete, Castellón, Cuenca, Soria, Teruel and Valencia in the Iberian Range, and Lleida (or Lérida) in the Pyrenean region. In 1958, Lapparent published the discovery of dinosaur eggs in the Tremp Basin (Lleida), the first ones found in the Iberian Peninsula. His 1960 work on the dinosaurs of Galve (Teruel) was the first monograph on the subject published in Spain. In 1965, Lapparent was also the first to publish the discovery of dinosaur footprints in Spain, more specifically in the province of Valencia.     

Advance directives in Spain. Perspectives from a medical bioethicist approach

Spain is one of the most advanced European countries in terms of the legislative and administrative development of ADs. Article 11 of Law 41/2002, concerning Patient Autonomy, regulates 'advance directives' and has prompted various Autonomous Regions to develop legislation in this area. Nevertheless, whilst the variety of legislations in different territories presents advantages, the disparity of criteria also presents problems.
Despite significant legislative development, only 23,000 Spanish citizens have filled in an AD. Clearly, AD use is confined to a minority. Several surveys, however, show that the Spanish population views these documents in a positive light. Thus, we must analyse this discrepancy between attitude and practice. A similar situation exists amongst health professionals. Whilst they generally feel that the use of ADs is positive and necessary, they are frequently unwilling to employ them.
Bioethical literature and research on ADs has significantly increased in Spain over the last six years. It is likely that this trend will continue in the foreseeable future; but more resources and effort are required if ADs are to become consolidated.
