Martínez Carrión, J. M.
Boletín de la Sociedad Espa?ola de Cerámica y Vidrio , 2001,
Abstract: This investigation emphasizes the historic relevance the sector traditionally comprising ceramics, glass, and building industry played in the Region of Murcia as well as its contribution to Spanish industrialization within the nineteenth century. First of all, it is analyzed the contribution of this sector to the manufacturing framework in both the Region of Murcia and the Spanish industry. From official records it is shown the industrial expecialization this sector reached during the second half of the XIXth century, sharing positions with mining and metallurgist and quite over food and textile sectors. Meanwhile, factors of industrial localization, spatial distribution of production, and changes occurred in the different sectors between 1856 and 1905 to evaluate the more dynamic aspects and their effects on the Spanish geography are analyzed. We conclude emphasizing the importance of this sector during the Restoration. El trabajo destaca la relevancia histórica que adquirió el sector que tradicionalmente engloba las industrias de ‘cerámica, vidrio y materiales de construcción’ en la región de Murcia y su contribución a la industrialización espa ola del siglo XIX. Primeramente, se examina la aportación del sector a la estructura fabril de la Región de Murcia y a la industria espa ola. A partir de fuentes fiscales se muestra la especialización industrial que el sector adquirió en la segunda mitad del siglo XIX, que comparte posiciones similares junto con las industrias metalúrgicas y mineras, muy por encima de los sectores alimentarios y textiles. Asimismo, se analizan los factores de localización industrial, la distribución espacial de la producción y los cambios producidos en sus diferentes ramas entre 1856 y 1905, con el fin de valorar los aspectos más dinámicos y su influencia en la geografía espa ola. Concluye se alando el protagonismo del sector durante el periodo de la Restauración.
La fábrica de cristal y vidrio de Santa Lucía (Cartagena) y el sector del vidrio espa ol (1834-1908)
Martínez Carrión, J. M.
Boletín de la Sociedad Espa?ola de Cerámica y Vidrio , 2002,
Abstract: This article is a contribution to the Spanish glass industry from the knowledge of Fabrica de Cristal y Vidrio de Santa Lucia (Cartagena) during the XIXth century. The evolution of this company is accomplished within the context of the Spanish sector underlining some phases: Its impulse during 1840′s and 1850′s, market problems and competition in the last decades of the XIXth century, and its restructuring at the beginning of the XXth century, which ended with an intense process of concentration and internationalization that affected plane glass and hollow glass. Likewise, industrial location factors, regional distribution of the production, and changes occurred in its various branches between 1856 and 1905 are reported. Data reveal the leading role of this factory from Cartagena in the glass industry and, particularly, its specialization in crystal, glassware of best quality, and white cut glass during the Restoration period. El trabajo contribuye al conocimiento de la industria del vidrio espa ol durante el siglo XIX a partir de la Fábrica de Cristal y Vidrio de Santa Lucia (Cartagena). La evolución de la empresa es analizada en el contexto del sector espa ol, destacándose varias fases: el impulso que vivió el sector en las décadas de 1840 y 1850, los problemas de mercado y competitividad en las décadas finales del siglo XIX y la reestructuración de comienzos del siglo XX. Esta última acabó con la formación de estructuras de oligopolio que afectaron a las ramas del vidrio plano y del vidrio hueco. Se destacan, asimismo, los factores de localización industrial, la distribución regional de la producción y los cambios acaecidos en sus diferentes ramas entre 1856 y 1905. Los datos aportados revelan el protagonismo de la empresa de Cartagena en el sector vidriero, y en particular su especialización en cristal y vidrio blanco tallado durante el periodo de la Restauración.

Estudio del polimorfismo de receptores FcgammaIIa en pacientes chilenos con lupus eritematoso sistémico Polymorphisms of FcgammaIIa receptors in Chilean patients with systemic lupus erythematosus

Revista médica de Chile , 2003,
Abstract: Background: Polymorphisms of Fc receptors for IgG (FcgR) have been proposed as a genetic factor that influences susceptibility for systemic lupus erythematosus (SLE). Human FcgRIIa has 2 codominantly expressed alleles, H131 and R131, which differ at amino acid position 131 in the second extracelular domain (histidine or arginine respectively) and differ substantially in their ability to bind human IgG2. The H131 allele binds IgG2 efficiently, whereas R131 binds it poorly. Because IgG2 is a poor activator of the classical complement pathway, the H131 is essential for the disposal of IgG2 immune complexes. Aim: To determine the distribution of FcgRIIA genes in a cohort of Chilean SLE patients, with or without a history of lupus nephritis. Patients and methods: We studied 52 Chilean SLE patients fulfilling the 1982 American College of Rheumatology (ACR) criteria, 20 of whom had a history of nephritis, and 44 ethnically matched disease-free controls. FcgRIIa allotypes were genotyped by PCR. Results: No significant association was observed between the low affinity FcgRII receptor (FcgRIIa-R131) and the presence of SLE or lupus nephritis. However, genotype frequencies in SLE patients but not in controls, departed from the proportions predicted by the Hardy-Weinberg equilibrium, suggesting this locus might be related to the disease. Conclusions: Our results suggest that in Chilean patients with SLE, as well as in many other populations, the R131 allotype is not a major factor predisposing to the development of SLE or lupus nephritis (Rev Méd Chile 2003; 131: 11-18)
Documento de consenso sobre el tratamiento antimicrobiano de las infecciones bacterianas odontogénicas Consensus statement on antimicrobial treatment of odontogenic bacterial infections

Abstract: Las infecciones de la cavidad bucal son un problema de salud pública frecuente y motivo constante de prescripción antibiótica; el 10% de los antibióticos se emplean para tratar este problema. Sin embargo, hasta la fecha son pocos los estudios realizados para determinar su incidencia. Asímismo, su relación con ciertas enfermedades sistémicas (cardiacas, endocrinas, etc...) confiere a estas patologías una importancia vital. A pesar de la reconocida frecuencia e importancia de las infecciones odontogénicas, llama la atención la actual dispersión de criterio en varios aspectos referentes a su clasificación, terminología y recomendaciones terapéuticas. El objetivo principal de este documento, realizado con el consenso de especialistas en microbiología y odontología, es establecer unas recomendaciones útiles para todos los profesionales implicados en el manejo clínico de estas patologías. Recibe especial atención el aumento de la prevalencia de resistencias bacterianas observado durante los últimos a os y, en concreto, la proliferación de cepas productoras de betalactamasas. Otro factor causal importante de la aparición de resistencias es la falta de cumplimiento terapéutico, en especial en lo que respecta a la dosis y a la duración del tratamiento. Así pues, estas patologías constituyen un problema complejo cuyo abordaje requiere la instauración de antimicrobianos de amplio espectro, con adecuados parámetros farmacocinéticos, con buena tolerancia y una posología cómoda que permita que el paciente reciba la dosis adecuada durante el tiempo necesario. Amoxicilina/ácido clavulánico a dosis altas (2000mg/ 125mg) ha demostrado buenos resultados y capacidad para superar resistencias. Otros agentes como metronidazol y clindamicina, seguidos de claritromicina y azitromicina han demostrado también ser activos frente a la mayoría de los microorganismos responsables de las infecciones odontogénicas. The infection of the oral cavity is a common public health problem and constant cause for antibiotic prescription, with 10% of antibiotics used to treat this problem. However, few studies have so far aimed to determine its incidence. Added to this, its relationship with certain sytemic diseases (cardiac, endocrine, etc…) confers this pathology vital importance. In spite of the frequency and importance of odontogenic infection, the current dispersion in criteria regarding key aspects in classification, terminology and therapeutic recommendations is noticeable. The main objective of this document, compiled as a consensus statement by specialists in microbiology and odontology,
“Ranking-based Ties” Social Networks. An illustration based on a system of Fashion Capital Cities in the world

Business Systems Review , 2012, DOI: 10.7350/bsr.a16.2012
Abstract: Our paper aims to apply a non-conventional Social Network Analysis to a network generated from an initial sorting of data with mere order. The aim is to test whether and how one relationship set "conveniently" generated by the ranking is able to provide a coherent system of interactions with possible practical and theoretical utility. We consider a system of city distributions where we focus on “Ranking-Based Ties” social networks, considering a system of "objects" of the same class that would be able to interact. The objects in question are ordered according to their "performance" in a particular ranking. According to a survey developed by Global Language Monitor, there is a ranked number for every capital that could be considered important among the world’s most fashionable cities. Using the rank of scoring average we construct a fashion cities network in order to analyze the dynamics and the topology of the system following a gradual process of clustering or densification of relationships consistent with key network statistics analysis.
The Stack: A New Bacterial Structure Analyzed in the Antarctic Bacterium Pseudomonas deceptionensis M1T by Transmission Electron Microscopy and Tomography
Lidia Delgado, Ornella Carrión, Gema Martínez, Carmen López-Iglesias, Elena Mercadé
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0073297
Abstract: In recent years, improvements in transmission electron microscopy (TEM) techniques and the use of tomography have provided a more accurate view of the complexity of the ultrastructure of prokaryotic cells. Cryoimmobilization of specimens by rapid cooling followed by freeze substitution (FS) and sectioning, freeze fracture (FF) and observation of replica, or cryoelectron microscopy of vitreous sections (CEMOVIS) now allow visualization of biological samples close to their native state, enabling us to refine our knowledge of already known bacterial structures and to discover new ones. Application of these techniques to the new Antarctic cold-adapted bacterium Pseudomonas deceptionensis M1T has demonstrated the existence of a previously undescribed cytoplasmic structure that does not correspond to known bacterial inclusion bodies or membranous formations. This structure, which we term a “stack”, was mainly visualized in slow growing cultures of P. deceptionensis M1T and can be described as a set of stacked membranous discs usually arranged perpendicularly to the cell membrane, but not continuous with it, and found in variable number in different locations within the cell. Regardless of their position, stacks were mostly observed very close to DNA fibers. Stacks are not exclusive to P. deceptionensis M1T and were also visualized in slow-growing cultures of other bacteria. This new structure deserves further study using cryoelectron tomography to refine its configuration and to establish whether its function could be related to chromosome dynamics.
