Informe final de la beca BE realizada en la California San Francisco

Investigación producida a partir de una estancia de dos meses en el laboratorio de la Dra. Donna M. Ferriero del departamento de neurología de la University of Californai San Francisco. A partir de un modelo de lesión cerebral isquemica en ratas postnatales, se han estudiado los efectos de la interacción con integrinas en el desarrollo de la lesión como estrategia terapéutica.

La formación del Estado en el Valle Medio del Río Amarillo. Un acercamiento teórico y práctico a los inicios de la Edad del Bronce en China

L’objectiu de l’estudi és respondre a la pregunta: Quan i emprant quins criteris es possible afirmar l’existència d’Estat a la Xina? A l’apartat teòric es realitza una revisió crítica de la categoria “Mode de Producció Asiàtic” i de les diferents definicions i causes de desenvolupament de l’Estat. Es presenten els fonaments d’una concepció materialista històrica de l’Estat. A l’apartat pràctic es contrasta la hipòtesi de l’existència d’Estat analitzant dues societats successives: els grups neolítics Henan Longshan (2800-1900 cal ANE) i els Erlitou d’inicis de l’Edat del Bronze (1900-1500 cal ANE)

Contribuição ao estudo de Histoplasma capsulatum (Darling, 1906)

Usando o meio de amônio-sulfato-glicose, conseguimos que oito amostras estéreis de Histoplasma capsulatum voltassem a produzir estalagmosporos.

Sobre uma nova espécie do gênero Acanthocolpus Lühe, 1906

Os autores, na presente nota, propõem Acanthocolpus brasiliensis sp. n. sendo este gênero pela primeira vez referido no Brasil. A espécie aqui descrita difere das demais do gênero pela ausência de espinhos na vagina e no ducto hermafrodita e pela presença de vitelinos em quase toda extensão da metade posterior do corpo.

La reconstrucción del espejo: el cuento español en la Antología de cuentistas españoles contemporáneos de Francisco García Pavón

El presente trabajo ofrece un estudio exhaustivo de la Antología de cuentistas españoles contemporáneos, de Francisco García Pavón, obra que contribuyó en su día a la difusión y consolidación del cuento en nuestro país. A través del análisis de las piezas contenidas en sus tres ediciones y de las relaciones que se establecen entre ellas, así como del estudio de la vida y la obra de cada uno de sus autores, puede observarse la evolución que ha experimentado el género en España desde los años de la primera posguerra hasta la década de los ochenta.

Did the cooperative start life as a Joint-Stock company? business law and cooperatives in Spain, 1869–1931

Studies of Spanish cooperatives date their spread from the Law on Agrarian Syndicates of 1906. But the first legislative appearance of cooperatives is an 1869 measure that permitted general incorporation for lending companies. The 1931 general law on cooperatives, which was the first act permitting the formation of cooperatives in any activity, reflects the gradual disappearance of the cooperative’s "business" characteristics. In this paper we trace the Spanish cooperative’s legal roots in business law and its connections to broader questions of the freedom of association, the formation of joint-stock enterprises, and the liability of investors in business and cooperative entities. Our account underscores the similarities of the organizational problems approach by cooperatives and business firms, while at the same time respecting the distinctive purposes cooperatives served.

First report of Temnocephala brevicornis Monticelli 1889 (Temnocephalidae: Platyhelminthes) in Argentina

Temnocephala brevicornis Monticelli 1889, ectosymbiont of Hydromedusa tectifera Cope 1869, is reported for the first time for Argentina. Numerous temnocephalans from Arroyo Villoldo in the locality of Magdalena, Buenos Aires, Argentina were stained in toto to be studied. This commensal species in turtles was originally cited in association with Hydromedusa maximiliani (Mikan) and Hydraspis radiolata Mikan in Brazil. Afterwards, it was found on other fresh water turtle species in Brazil and Uruguay.

Stomach content analyses of Simulium perflavum Roubaud 1906 (Diptera: Simuliidae) larvae from streams in Central Amazônia, Brazil

Stomach contents of Simulium perflavum Roubaud larvae were analyzed and compared with plankton and periphyton collected in five streams, in Central Amazonia (Manaus and Presidente Figueiredo counties), in Sep./Oct.1996 (dry season) and Feb./Mar. 1997 (rainy season). A total of 1,400 last-instar larvae were dissected; the stomach contents were analyzed using different methods: fresh and after oxidation. A total of 87 taxa (algae, diatoms and rotifers) were found in the stomach contents. In each stream, qualitative samples of plankton and periphyton were collected; these were mounted between slides and cover slips. A total of 94 taxa of plankton and 54 taxa of periphyton were collected. One species of Rotifera was present in the stomach contents, plankton and periphyton. Cluster analysis based on species composition of the organisms present in the stomach contents grouped the streams into two major groups, each belonging to a different drainage area. Correlations based on presence/absence of species of microalgae in the stomach contents, plankton and periphyton indicated significant associations (p<0.05) between stomach contents and plankton and between plankton and periphyton (z test); the Sorensen coefficient and cluster analysis corroborate the same associations.
