Economic Integration, Competition and Hierarchization of the Atlantic Ports of Northern Spain (13 th-15 th centuries)
Resumen: El objetivo de este artĂculo es analizar las relaciones y la jerarquĂa de las villas portuarias del AtlĂĄntico norte de España entre los siglos XIII y XV. Los puertos del norte peninsular operaban en un nivel intermedio, regional e internacional, de la estructura comercial europea. Las cincuenta villas portuarias de la costa cantĂĄbrica desempeñaron un papel vital en la conectividad urbana del trĂĄfico marĂtimo internacional entre el MediterrĂĄneo y el AtlĂĄntico. El fenĂłmeno portuario del CantĂĄbrico, a pesar de su falta de homogeneidad, fue un Ă©xito porque se basĂł en algunos factores claves, como las caracterĂsticas geogrĂĄficas, las infraestructuras portuarias, el apoyo regio y unas sociedades muy dinĂĄmicas; ademĂĄs, la polĂtica y la gobernanza adoptaron unas caracterĂsticas comunes y distintas en estas villas perifĂ©ricas para responder a las necesidades y condiciones locales, muy influidas por su carĂĄcter de frontera marĂtima de la Corona de Castilla.Abstract: The aim of this article is to analyze the relationships and the hierarchy of the port-towns of Atlantic Northern Spain between the 13th and 15th centuries. The port-towns operated in an intermediate level, both regional and international, of the European trade structure. The half a hundred port-towns on the Cantabrian coast played a vital role in the urban connectivity of the international maritime traffi c between the Mediterranean and the Atlantic. This phenomenon, despite lacking an homogeneity, was a success because it was based on some key factors, such as geographical features, port infrastructures, royal support and very dynamic societies. Besides, politics and governance adopted common and distinct characteristics in these peripheral towns to respond to local needs and conditions, very infl uenced by their character as a maritime border of the kingdom of Castile.Este trabajo se inscribe en las tareas de investigaciĂłn de los proyectos: âPolĂtica, instituciones y gobernanza de las villas y ciudades portuarias de la Europa AtlĂĄntica en la Baja Edad Media: anĂĄlisis comparativo transnacionalâ (HAR2017-83801-P); de la Red de Excelencia La Gobernanza de los puertos atlĂĄnticos, siglos XIV-XXI (HAR2016-81812-REDT) y âSocial and Political Order of the Communal Towns in the European Peripheries from the 12th to 16th Centuryâ (340880, ARMONIA, HS3)
ComparaciĂłn de diferentes parĂĄmetros de evaluaciĂłn en sujetos con asma moderada estable sin exacerbaciĂłn microbiana, tratados con Salmeterol-Fluticasona vs Ciclesonida y Salbutamol a demanda
El asma es una entidad clĂnica caracterizada por la combinaciĂłn de tres
factores: obstrucciĂłn de la vĂa aĂ©rea con reversibilidad espontĂĄnea y/o
farmacolĂłgica, hiperrreactividad bronquial e inflamaciĂłn local. Existen
numerosas alternativas farmacolĂłgicas para el tratamiento de esta enfermedad.
En el presente trabajo se compararon parĂĄmetros de evaluaciĂłn del estado
asmĂĄtico moderado, los episodios de exacerbaciĂłn de etiologĂa bacteriana y la
colonizaciĂłn bucal por hongos en dos grupos de pacientes; 15 tratados con
ciclesonida en dosis alta y salbutamol a demanda y 13 con salmeterol
fluticasona en dosis fija durante 300 dĂas de tratamiento. Hasta el momento se
observó que ambas alternativas terapéuticas son vålidas para el control de la
enfermedad, ya que a pesar de la presencia en esputo, de bacterias
potencialmente capaces de producir exacerbaciones, estas no ocurrieron
durante el tiempo del estudio. La colonizaciĂłn por hongos de la cavidad oral se
presentĂł en ambos grupos. Los parĂĄmetros de funciĂłn pulmonar fueron
comparables.Fil: Sagua, M..

Afecciones respiratorias superiores en aves de criaderos de Mendoza
En los Ășltimos meses de 2010 criaderos de gallinas de la provincia de Mendoza padecieron afecciones respiratorias superiores de caracterĂsticas agudas. La incidencia fue alta, siendo muy baja la letalidad de los casos. Se presenta la metodologĂa de trabajo utilizada para diagnĂłstico virolĂłgico, bacteriolĂłgico y micolĂłgico, junto a los resultados hallados
Landscape dynamics and fire activity since 6740 cal yr BP in the Cantabrian region (La Molina peat bog, Puente Viesgo, Spain)
A lack of paleobotanic studies with adequate resolution and multiproxy approaches has limited proper discussion of vegetation dynamics in Cantabria and of the role of fires in the configuration of the plant landscape during the Holocene in the northwest part of the Iberian peninsula. The pollen diagram of La Molina peat bog in Puente Viesgo (43 âč15 Ć38 N.3 âč58 Ć37 W; ETRS89), located at 484 m.a.s.l., and the study of its sedimentary charcoals allowed the acquisition of a continuous and thorough fire sequence for the last 6 700 cal yr BP and an understanding of its relationship to the forest. The results show the importance of human influence on the incidence and characteristics of fire activity during the different phases studied: the Neolithic, Bronze Age, Iron Age, Roman period, and Middle Ages. A synergy seems to exist between dry climate periods (especially during Bond events 3 and 4) and a greater presence of biomass. As the Holocene advances, vegetation coverage clearly tends to decrease. This study provides key elements for understanding the role of fire activity in the forest dynamics of deciduous and evergreen Quercus, Corylus, Pinus, Fagus, and Alnus and demonstrates the strongly artificialized character of the present landscape
Adverse Drug Reactions in ChildrenâA Systematic Review
Adverse drug reactions in children are an important public health problem. We have undertaken a systematic review of observational studies in children in three settings: causing admission to hospital, occurring during hospital stay and occurring in the community. We were particularly interested in understanding how ADRs might be better detected, assessed and avoided
International Nosocomial Infection Control Consortium report, datasummary of 50 countries for 2010-2015 : Device-associated module
Q3ArtĂculo original1495-1504Background: We report the results of International Nosocomial Infection Control Consortium (INICC) sur-veillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America,Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific.Methods:During the 6-year study period, using Centers for Disease Control and Prevention National Health-care Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregateof 3,506,562 days.Results:Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAIrates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associatedpneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples,frequencies of resistance ofPseudomonasisolates to amikacin (29.87% vs 10%) and to imipenem (44.3%vs 26.1%), and ofKlebsiella pneumoniaeisolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27%vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs.Conclusions:Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported inCDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the re-duction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICCâs main goal tocontinue facilitating education, training, and basic and cost-effective tools and resources, such as stan-dardized forms and an online platform, to tackle this problem effectively and systematically

Advances in the study of intracellular transport of brucela abortus 2308 (virulent strain) in macrophages
In recent years, this research team has progressed in the study of intracellular transport of the virulent strain (2308) of Brucella abortus in macrophage cell lines (J-774 and Raw) through multiple microscopic approaches. We demonstrated the transit of B. abortus 2308 through compartments of the endocytic pathway, marking early endosomes and lysosomes with gold (20 and 60 nm, respectively). We have shown that B. abortus 2308 occupies two different types of compartments: phagolysosomes and modified phagosomes, significantly reducing their fusion to endosomes. On the other hand, macrophages transfected with GFP-Rabs were used to evaluate the location of Rab 5 and 11 proteins, involved in the vesicular transport of the cell. Confocal microscopy showed that B. abortus 2308 (stained with Rhodamine) recruits Rab11 to the phagosome membrane that contains them, in the form of discrete patches. In addition, B. abortus 2308 co-locates with vesicles that overexpress Rab 5 in a large proportion. The permanence of Rab 5 and 11 associated with phagosomes containing B. abortus 2308 suggests that the bacteria actively retain these Rabs to avoid maturation of the phagosome that contains them. Subsequently, the effect of kinase inhibitors (AKTi) on the multiplication and intracellular survival of B. abortus 2308 at different times post macrophage infection was studied by confocal microscopy. These results allowed confirming that B. abortus 2308 uses the AKT/AS160 pathway to activate Rabs involved in the transport of nutrients necessary for its replication and the generation of a safe intracellular site. The compound used as an AKT inhibitor could constitute a new pharmacological approach for the treatment of brucellosis.Fil: Degarbo, S. M.. Universidad Nacional de Cuyo. Facultad de Cs.mĂ©dicas.
