Infecção por Enterobius vermicularis em populações agro-pastoris pré-colombianas de San Pedro de Atacama, Chile

Enterobius vermicularis eggs were found in human coprolites collected from the archaeological site of San Pedro de Atacama, North of Chile, in occupational layers dated from 1,000 BC. Agricultures and herding were begining at this period of time in this region of South America. The paleoparasitological data amplifies the knowledge about the distribution of human oxyuriasis in Pre-Columbian America.

The Early Cretaceous San Juan Plutonic Suite, Ecuador: A magma chamber in an oceanic plateau ?

Sections through an oceanic plateau are preserved in tectonic slices in the Western Cordillera of Ecuador (South America). The San Juan section is a sequence of mafic-ultramafic cumulates. To establish that these plutonic rocks formed in an oceanic plateau setting, we have developed criteria that discriminate intrusions of oceanic plateaus from those of other tectonic settings. The mineralogy and crystallization sequence of the cumulates are similar to those of intra-plate magmas. Clinopyroxene predominates throughout, and orthopyroxene is only a minor component. Rocks of intermediate composition are absent, and hornblende is restricted to the uppermost massive gabbros within the sequence. The ultramafic cumulates are very depleted in light rare-earth elements (LREE), whereas the gabbros have flat or slightly enriched LREE patterns. The composition of the basaltic liquid in equilibrium with the peridotite, calculated using olivine compositions and REE contents of clinopyroxene, contains between 16% and 8% MgO and has a flat REE pattern. This melt is geochemically similar to other accreted oceanic plateau basalts, isotropic gabbros, and differentiated sills in western Ecuador. The Ecuadorian intrusive and extrusive rocks have a narrow range of epsilonNd(i) (+8 to +5) and have a rather large range of Pb isotopic ratios. Pb isotope systematics of the San Juan plutonic rocks and mineral separates lie along a mixing line between the depleted mantle (DMM) and the enriched-plume end members. This suggests that the Ecuadorian plutonic rocks generated from the mixing of two mantle sources, a depleted mid-oceanic ridge basalt (MORB) source and an enriched one. The latter is characterized by high (Pb-207/Pb-204)(i) ratios and could reflect a contamination by recycled either lower continental crust or oceanic pelagic sediments and (or) altered oceanic crust (enriched mantle type I, EMI). These data suggest that the San Juan sequence represents the plutonic components of an Early Cretaceous oceanic plateau, which accreted in the Late Cretaceous to the Ecuadorian margin.

Urban ecology of Triatoma infestans in San Juan, Argentina

This study was performed in an urban neighborhood of the capital city of the province of San Juan, Argentina. Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development - nymph or adult - and how these insects had entered their homes. Adult T.infestans were found on all floors; 163 people (64%) had found them at least once, and 130 (51%) several times. Dispersal flight seems to have been the main mechanism of infestation by adult bugs in this area, and a total of 51% of the surveyed inhabitants reported that the insects had flown into their flats.

Estudio del ecosistema urbano de San José. Protocolo de monitoreo de aves y naturalización del Parque La Sabana

El papel de la ciudad en el futuro de la humanidad será transcendente, y es que el crecimiento actual de los espacios urbanos tiende, en general, a desbordar el sitio original de las ciudades, abarcando territorios cada vez más extensos y discontinuos. Y por este motivo es de vital importancia el estudio de la ciudad y de su entorno, el cual es sinónimo de ecosistema urbano. En el siguiente estudio se evalúa el ecosistema urbano de San José, capital de Costa Rica, dando énfasis en las zonas verdes presentes, en las relaciones con los ecosistemas naturales circundantes y como mejorar su capacidad ecológica. Por este motivo se ha analizado un proceso de rearborización en el Parque Metropolitano La Sabana, principal nódulo de carga de la trama urbana. Este esfuerzo de naturación dotará al parque de una mayor naturalización, con lo que se espera un aumento de la biodiversidad faunística. Para conocer estos cambios se crea un programa de monitoreo de aves con su respectivo protocolo.

Population dynamics of intermediate snail hosts of Fasciola hepatica and some environmental factors in San Juan y Martinez municipality, Cuba

The variation of abundances of intermediate snail hosts of Fasciola hepatica in Cuba (Fossaria cubensis and Pseudosuccinea columella) was studied during one year under natural conditions at five sampling sites in San Juan y Martinez municipality, Pinar del Rio province, Cuba. The effect of some environmental variables on the lymnaeid abundances was also studied. A canonical correspondence analysis showed that both species do not generally occur together in the same habitat and that most factors affect them in an opposite fashion, although both of them correlate positively through time to the diversity of the habitats. F. cubensis prefers the sites that are in or closer to the city whereas P. columella is more abundant in rural sites. Lymnaeid abundances are mainly affected by nitrite and nitrate concentrations as well as by the abundance of the thiarid Tarebia granifera. F. cubensis is more abundant in polluted habitats with low densities (or absence) of T. granifera whereas P. columella prefers cleaner habitats and can coexist with the thiarid, even at its higher densities. The implications of divergent preferences of the two lymnaeids for the control of fasciolosis are discussed.

L'auteur s'essaie à la description minutieuse afin de montrer, à partir d'une perspective pragmatique, le développement des actions dans l'espace et dans le temps, permettant de mettre en évidence le savoir pratique et la créativité de ses interlocuteurs, ainsi que la dimension d'indétermination des situations. Par ce faire, aucune explication sous-jacente ou cachée est recherchée, le sens se trouvant dans la pratique festive même. L'abondance des détails a également pour objectif de faire vivre aux lecteurs les situations et de leur faire prendre conscience de leur caractère complexe et situé.

The Ladinian flora from the Cassina beds (Meride Limestone, Monte San Giorgio, Switzerland): Preliminary results

A newly opened excavation in the Cassina beds of the Lower Meride Limestone (Monte San Giorgio UNESCO WHL, Canton Ticino, Southern Alps) has yielded a small collection of Ladinian plant fossils, together with vertebrate (mostly fish) and invertebrate remains The flora contains at least five species, conifer remains assignable to the genera Elatocladus, Voltzia and Pelourdea are the most common elements A new species, Elatocladus cassinae n Sp, is formally, described Co-occurring with the conifers arc seed ferns (Ptilozamites) and a few putative cycadalean remains (Taemopteris) Among the identified genera, only Volizia has previously been reported from Monte San Giorgio The fossils presented in this paper indicate that a diversified flora thrived in the region during the Ladman Floral composition and preservation patterns are suggestive of a taphonomically-biased record and a relatively far-away source area

Embarazo, parto y puerperio: creencias y prácticas de parteras en San Luis Potosí, México

OBJETIVO: Documentar las creencias y las prácticas de las parteras tradicionales respecto al embarazo parto y puerperio. MÉTODOS: Aprovechando un curso de capacitación de 160 parteras tradicionales locales de las regiones Media y Huasteca del Estado de San Luis Potosí, México, dos de las enfermeras-instructoras entrevistaron a 25 de los capacitandos, apoyadas por un miembro de las comunidades náhuatl y tenek. La identidad de los participantes se mantiene anónima y se obtuvo permiso para publicar los resultados mediante consentimiento informado. RESULTADOS: Las prácticas de las parteras (os) tradicionales son comunes en los grupos sociales que carecen de servicios de salud. Sus funciones no están limitadas al parto e incluyen nutrición, cuidados prenatales, del puerperio y la lactancia, así como apoyo afectivo emocional de las madres parturientas y sus familiares. En este estudio se registraron varios mitos y terapias tradicionales. CONCLUSIÓN: Los recursos de la terapia tradicional y de la atención primaria de la salud de las parteras Náhuatl y Tenek son útiles y benéficos para los cuidados perinatales.

Plan de Gestión de la red de senderos ecoturísticos de la Sierra de San Javier, Tucumán- Argentina

El “Parque Sierra de San Javier” és un espai natural al costat d’ un gran nucli urbà, San Miguel de Tucumán (Argentina). A la Sierra es troba la comuna de San Javier, on s’ ha creat el CIC (Centre Integrador Comunitari). És a partir del CIC que s’ elabora un pla integral que inclou el projecte d’ ecoturisme. Aquest projecte es basa en una gestió de la xarxa de camins existents a la Sierra. Es fa un inventari de cadascun dels camins de la xarxa i s’ analitza cadascun d’ ells amb uns índexs de potencial paisatgístic i interpretatiu i es valora també la seva conservació. A partir d’ aquests valors es planteja un pla d’ actuació de recuperació i manteniment, i un pla d’ actuació turística en el que es millora l’ estat del camí; s’ intal•len panells informatius i senyalització. El projecte conté les fitxes d’ informació de cadascun dels itineraris amb un mapa i amb d’ altres informacions d’ interès pels usuaris dels senders

Arnau de Montrodon y la catedral de San Carlomagno. Sobre la imagen y el culto al emperador carolingio en Gerona

In 1345, the unique worship of Saint Charlemagne was institutionalized in the cathedral of Gerona. The roots (and for many, the reasons) of this celebration are found in the existence of an old local legend, the well-known testimonies to which go back to the eleventh century. Nevertheless, a lengthy analysis of the facts that marked the life of the cathedral during the long permanence Amau de Montrodon had there—first in quality of canon (1297-1335) and later as bishop (1333-1348)- make it possible for us to verify that the promotion of the cult to San Charlemagne falls within a complex program of ideological and symbolic exaltation of the See of Girona that was designed by this notable and restlessly active ecclesiastic
