Apoptosis in sea urchin embryos.
1997
Abstract It is demonstrated by DNA electrophoresis analysis, morphological observations and TdT in situ reaction, that Paracentrotus embryos if treated with TPA plus heat undergo an apoptotic reaction. Indication is also obtained that non treated embryos undergo spontaneous apoptosis at the early pluteus stage, expecially in the districts of arms and intestine. The possible meaning of this latter observation is discussed.
Nuevos ligandos poliamínicos de tipo escorpiando para aplicaciones biomédicas
2016
La presente Tesis Doctoral nace en el marco del proyecto Consolider titulado “Aplicación de la Química Supramolecular al Diseño, Síntesis y Estudio de Compuestos Bioactivos de Acción Antiinflamatoria, Antitumoral o Antiparasitaria” (CSD2010-00065, BOE del 27 de febrero de 2010). El principal objetivo de este proyecto era la formación en España de un grupo de investigación multidisciplinar dedicado a la Química Médica Supramolecular (SUPRAMED, www.supramedic.com) que centraría sus esfuerzos, como su nombre indica, en el desarrollo de nuevos agentes terapéuticos con actividad antiparasitaria, antiinflamatoria o antitumoral. Como miembro investigador en este proyecto (dentro del grupo de Quími…
Chemie von Aerosolen
2007
Atmospharische Aerosolpartikel sind keine chemisch inerten Teilchen, deren Bildungsmechanismen, Verweildauer oder Funktion in der Atmosphare lediglich von mechanischen oder physikalischen Prozessen abhangen. Sowohl bei der Bildung von Aerosolpartikeln als auch im Verlauf ihres Verbleibs in der Atmosphare spielen chemische Reaktionen eine wesentliche Rolle. Chemische Reaktionen laufen an der Oberflache und im Inneren von Aerosolpartikeln ab und konnen sowohl die atmospharische Gasphasenchemie beeinflussen, z.B. indem sie sowohl als Reaktionsmedium fur ansonsten langsam verlaufende Gasphasenreaktionen dienen, als auch die Eigenschaften der Partikel, beispielsweise ihre Funktion als Kondensati…

ITS1 region of the rDNA of Pythium megacarpum sp. nov., its taxonomy, and its comparison with related species.
2000
Pythium megacarpum sp. nov., was isolated from a soil sample taken from a wheat field in Lille in northern France. It was mistakenly described as Pythium ostracodes Drechsler [Paul, B (1994) Cryptogam. -Mycol. 15,263-271]. Despite morphological resemblance, the comparison between the internal transcribed spacer (ITS)1 regions of the rDNA of the two fungi, leaves no doubt of their different identities. This species is unique because of its large oogonia and plerotic, thick walled oospores, its monoclinous antheridia with large antheridial cells and its lack of zoospores. The character combination of P. megacarpum and the ITS1 sequence of its rDNA, justifies the creation of a new species with…

Septal complex of the telencephalon of the lizardPodarcis hispanica. II. afferent connections
1997
The afferent connections to the septal complex were studied in the lizard Podarcis hispanica (Lacertidae) by means of a combination of retrograde and anterograde tracing. The results of these experiments allow us to classify the septal nuclei into three main divisions. The central septal division (anterior, lateral, dorsolateral, ventrolateral, and medial septal nuclei plus the nucleus of the posterior pallial commissure) receives a massive, topographically organized, cortical projection (medial, dorsal, and ventral areas) and widespread afferents from the tuberomammillary hypothalamus and the basal telencephalon. Moreover, it receives discrete projections from the dorsomedial anterior thal…
Impact of Manaus City on the Amazon Green Ocean atmosphere: Ozone production, precursor sensitivity and aerosol load
2010
As a contribution to the Large-Scale Biosphere-Atmosphere Experiment in Amazonia – Cooperative LBA Airborne Regional Experiment (LBA-CLAIRE-2001) field campaign in the heart of the Amazon Basin, we analyzed the temporal and spatial dynamics of the urban plume of Manaus City during the wet-to-dry season transition period in July 2001. During the flights, we performed vertical stacks of crosswind transects in the urban outflow downwind of Manaus City, measuring a comprehensive set of trace constituents including O3, NO, NO2, CO, VOC, CO2, and H2O. Aerosol loads were characterized by concentrations of total aerosol number (CN) and cloud condensation nuclei (CCN), and by light scattering proper…
