The Ecology of Bacterial Genes and the Survival of the New
M. Pilar Francino
International Journal of Evolutionary Biology , 2012, DOI: 10.1155/2012/394026
Abstract: Much of the observed variation among closely related bacterial genomes is attributable to gains and losses of genes that are acquired horizontally as well as to gene duplications and larger amplifications. The genomic flexibility that results from these mechanisms certainly contributes to the ability of bacteria to survive and adapt in varying environmental challenges. However, the duplicability and transferability of individual genes imply that natural selection should operate, not only at the organismal level, but also at the level of the gene. Genes can be considered semiautonomous entities that possess specific functional niches and evolutionary dynamics. The evolution of bacterial genes should respond both to selective pressures that favor competition, mostly among orthologs or paralogs that may occupy the same functional niches, and cooperation, with the majority of other genes coexisting in a given genome. The relative importance of either type of selection is likely to vary among different types of genes, based on the functional niches they cover and on the tightness of their association with specific organismal lineages. The frequent availability of new functional niches caused by environmental changes and biotic evolution should enable the constant diversification of gene families and the survival of new lineages of genes. 1. Introduction Genomic science has brought about the possibility of disclosing the genetic underpinnings of entire organisms, and, for microbes, even of complex populations and communities. In doing so, it has unearthed a good number of surprising facts regarding the structure, organization, and variability of genomes, with strong evolutionary implications. In bacteria, the relatively small size of genomes has warranted the obtention of entire genomic sequences for a vast number of organisms, including numerous sets of sequences of closely related taxa. As genome sequences of closely related bacteria have accumulated, our view of bacterial genomes has radically changed. Genome comparisons have demonstrated that little 16S rRNA sequence divergence can be accompanied by large differences in total gene repertoire [1–7], and that even populations of a single 16S rRNA species can be made up of vast numbers of genomic varieties [8]. Much of the observed variation among closely related bacterial genomes has been attributed to gains and losses of genes that are acquired horizontally, often by way of mobile genetic elements (MGEs) as well as to a variety of genomic rearrangements that include gene duplications and large gene

Revista chilena de infectología , 2010,
Abstract: Brucelosis es una infección poco frecuente en Chile pero que puede presentar algunas complicaciones graves como endocarditis. Se presenta el caso de un paciente de 74 a os que ingresa al Hospital de Enfermedades Infecciosas Dr Lucio Córdova (HLC) de Santiago, con un síndrome febril de 3 meses de evolución, sin síntomas específicos. El ecocardiograma trans-esofágico mostró múltiples vegetaciones en válvula aórtica y en los hemo-cultivos se desarrolló Brucella abortus. El paciente recibió tratamiento médico-quirúrgico en el Instituto de Enfermedades Respiratorias y Cirugía de Tórax (INERYCT), evolucionando satisfactoriamente. Ante un paciente con un síndrome febril prolongado debe tenerse presente la posibilidad diagnóstica de brucelosis de modo de solicitar los exámenes específicos en forma oportuna y, si se confirmase, iniciar precozmente el tratamiento. Este debe comprender un esquema asociado de antimicrobianos, que se mantendrá por al menos 4 a 6 semanas. En caso de endocarditis, con frecuencia se requerirá también de reemplazo valvular.

Abstract: Se presenta el caso de un paciente de sexo masculino de 51 a os con cuadro clínico de dengue contraído en Isla de Pascua durante el verano del 2002. Este caso se produjo durante la epidemia de esta enfermedad, que ocurrió en ese territorio, a partir de febrero- marzo de ese a o. El paciente tuvo una evolución favorable y su diagnóstico fue confirmado mediante serología (IgM) en el Instituto de Salud Pública (ISP). Fue el segundo caso de dengue autóctono diagnosticado durante la epidemia, y el primero en ser atendido en un hospital del servicio público de salud de Santiago. Se revisa brevemente el cuadro clínico y criterios diagnósticos para esta enfermedad. We present the case of a 50 year old male patient with dengue acquired at Easter Island in the summer of 2002. This occurred in the context of the epidemic of this disease, that started on the island in February 2002. The patient had a mild illness and the diagnosis was made by serology (IgM) done by the Reference Laboratory at the Public Health Institute. This patient was the second with a diagnosis of autochthonous dengue and the first to be admitted to a Public Health Service Hospital in Santiago. We briefly review the clinical features and the laboratory tests that contribute to the diagnosis.
El poema sacro Melo-dramático de Buono Chiodi (Santiago de Compostela, 1773)
Pilar Alén, M.
Anuario Musical , 2009,
Abstract: Several authors allude in their studies to the existence of an “opera” composed by the teacher of the cathedral of Santiago de Compostela, Buono Chiodi, for the 1773 Holy Year. At this moment it has not been possible to fi nd any track of the music of such a work, consequently we cannot declare on the quality of this one. Despite everything, it’s of supreme interest the libretto appeared recently between the funds of the National Library. For the subject that approaches —the Adjournment of the body of Apostle Santiago at the expense of their disciples, from Jerusalem to the current Compostela—, as well as for the circumstances that surround their premiere in the festivity of the Holy Boss of Spain, supported by the Chapter of Santiago, undoubtedly, it can be considered a manifestation submitted to the cathedral clergy power opposite to other power, civil and religious, of the town. Varios autores aluden en sus estudios a la existencia de una “ópera” compuesta por el maestro de la catedral de Santiago de Compostela Buono Chiodi, para el A o Santo de 1773. Hasta la actualidad no ha sido posible hallar ningún rastro de la música de tal obra, por lo que no podemos pronunciarnos sobre la calidad de la misma. Pese a todo, es de sumo interés el libreto, recientemente aparecido entre los fondos de la Biblioteca Nacional. Tanto por la temática que aborda —la Traslación del cuerpo del Apóstol Santiago desde Jerusalén a Compostela— como por haber estado auspiciado su estreno por el Cabildo de Santiago, sin duda, puede considerarse una obra al servicio del poder del clero catedralicio frente a otros poderes, civiles y religiosos, de la ciudad.

Avances en Psicología Latinoamericana , 2004,
Abstract: Analizamos la relación entre autoestima y salud y las variables más asociadas con autoestima enuna muestra de mujeres espa olas (N = 2583) de edades comprendidas entre 18 y 65 a os.Encontramos que las mujeres con más confianza en sí mismas y las que se valoraban de forma más positiva tenían mejor salud, mostrando menos síntomas depresivos, de ansiedad, somáticos ydisfunción social. Las mujeres que se valoraban de forma más negativa se caracterizaban por tenerun estilo de afrontamiento del estrés emocional y las mujeres con mayor confianza en sí mismastenían un estilo de afrontamiento más racional y menos emocional. Aunque la influencia de losfactores sociodemográficos era muy escasa, la autoestima era algo mayor en las mujeres con nivelde estudios universitario, en las que tenían empleos de mayor nivel, en las casadas y en las que teníanuno o dos hijos.
Contemporaneity of Spanish Rural Architecture Intervention and Economic Sustainability  [PDF]
Joan Curós Vilà, M. Pilar Curós Vilà
Art and Design Review (ADR) , 2017, DOI: 10.4236/adr.2017.51005
Abstract: From the second half of the 20th century onwards, Spanish rural architecture has suffered a transformation regarding its farming and ranching model. The economic unsustainability of the family economy has led to further action for the viability of the system. This transformation has meant a new mindset to the owner of the farm and livestock, who had to consider whether continuity was given to the exploitation or the countryside/field was changed and adapted to a new use such as rural tourism, restoration, or for collective uses such as holiday camps, cultural centers or others. Owners who have decided to continue the exploitation they were developing have had to industrialize it and thus extend it in a considerable percentage. That has meant the need to intervene significantly in the rural architectural heritage. A wide and varied range of results has been obtained in these interventions: from the fossilization or destruction of assets, to the achievement of harmony and coexistence between tradition and modernity in this heritage, the result of which represents the contemporaneity of rural architecture.
Profilaxis de neumonía por Pneumocystis jiroveci en ni os y adultos sometidos a trasplante de órganos sólidos y de precursores hematopoyéticos Prophylaxis against Pneumocystis pneumonia in pediatric and adult patients undergoing solid organ or hematopoietic stem cells transplantation
M. Pilar Gambra,Teresa Bidart
Revista chilena de infectología , 2012,
Abstract: Pneumocystis jiroveci es un patógeno importante en pacientes sometidos a TOS y TPH. Se recomienda proilaxis universal a todos los pacientes adultos y ni os sometidos a TOS o TPH porque su uso reduce signiicati-vamente la ocurrencia y mortalidad asociada a neumonía por este agente. El medicamento de elección es cotrimoxa-zol (A1) tres veces por semana, en dosis bajas, esquema que ha demostrado igual eicacia y mejor tolerancia que el esquema diario y/o con dosis altas. La proilaxis se inicia 7 a 14 días post trasplante en TOS y posterior al implante en TPH, con una duración promedio de 6 meses salvo en trasplante de hígado y pulmón en que se prolonga por 1 a o, al igual que en TPH con grado importante de inmunosupresión. Son alternativas de profilaxis dapsona (B2), pentamidina aerosolizada (B2) y atavacuona (C2). Pneumocystis jiroveci is an important pathogen in patients undergoing SOT and HSCT. Universal prophylaxis is recommended for all adults and children with SOT and HSCT, considering that its use significantly reduces the occurrence and mortality associated with pneumonia by this agent. The drug of choice is cotrimoxazole (A1) three times a week, low-dose scheme, that has proved equally effective and better tolerated than the daily regimen and/or at high doses. Prophylaxis starts 7 to 14 days post transplant in SOT recipients and post-implant in HSCT, with an average duration of 6 months except in liver and lung transplant as in HSCT with significant degree of immunosuppression, that lasts for 1 year. Alternatives for prophylaxis are dapsone (B2), aerosolized pentamidine (B2) and atovaquone (C2).
