Transcontinental 2200 km migration of a Nathusius’ pipistrelle (Pipistrellus nathusii) across Europe
2021
A male Pipistrellus nathusii ringed in Pape Natural Park (S Latvia) in August 2015 was recovered recently dead in Pitillas’ Lagoon Natural Reserve (N Spain) in March 2017. At 2224 km in SSW direction, this is the first documented bat migration between these countries and worldwide the longest migration record of a bat. We also report other observations of this species in autumn in Northern Spain, suggesting that the Iberian Peninsula may be an important wintering area for Nathusius’ pipistrelles. Conservation measures should be agreed on by countries along the migration routes to improve the protection of this species. nonPeerReviewed
Fructose 2,6-bisphosphate as a signal for changing from sugar to lipid oxidation during flight in locusts
1986
AbstractFlight in locusts is initially powered mainly by carbohydrate but if flight is to be sustained, as in migration, the animals have to utilize fat as the predominant fuel. The molecular basis of this metabolic switch has not been identified. Fructose 2,6-bisphosphate is a potent activator of 6-phosphofructokinase (EC 2.7.1.11) purified from locust flight muscle. After the first few minutes of flight in the locust the concentration of fructose 2,6-bisphosphate in the flight muscle falls dramatically, which should lead to a decrease in the activity of 6-phosphofructokinase as part of the mechanism to conserve carbohydrate during prolonged flight.
Notch and Numb are required for normal migration of peripheral glia in Drosophila
2006
Abstract A prominent feature of glial cells is their ability to migrate along axons to finally wrap and insulate them. In the embryonic Drosophila PNS, most glial cells are born in the CNS and have to migrate to reach their final destinations. To understand how migration of the peripheral glia is regulated, we have conducted a genetic screen looking for mutants that disrupt the normal glial pattern. Here we present an analysis of two of these mutants: Notch and numb. Complete loss of Notch function leads to an increase in the number of glial cells. Embryos hemizygous for the weak NotchB-8X allele display an irregular migration phenotype and mutant glial cells show an increased formation of …
3-(6-Phenylimidazo [2,1-b][1,3,4]thiadiazol-2-yl)-1H-Indole Derivatives as New Anticancer Agents in the Treatment of Pancreatic Ductal Adenocarcinoma
2020
A new series of imidazo[2,1-b][1,3,4]thiadiazole derivatives was efficiently synthesized and screened for their in vitro antiproliferative activity on a panel of pancreatic ductal adenocarcinoma (PDAC) cells, including SUIT-2, Capan-1 and Panc-1. Compounds 9c and 9l, showed relevant in vitro antiproliferative activity on all three pre-clinical models with half maximal inhibitory concentration (IC50) ranging from 5.11 to 10.8 µ

3-(6-Phenylimidazo [2,1-
2019
A new series of imidazo[2,1-b][1,3,4]thiadiazole derivatives was efficiently synthesized and screened for their in vitro antiproliferative activity on a panel of pancreatic ductal adenocarcinoma (PDAC) cells, including SUIT-2, Capan-1 and Panc-1. Compounds 9c and 9l, showed relevant in vitro antiproliferative activity on all three pre-clinical models with half maximal inhibitory concentration (IC50) ranging from 5.11 to 10.8 µM, while the compounds 9e and 9n were active in at least one cell line. In addition, compound 9c significantly inhibited the migration rate of SUIT-2 and Capan-1 cells in the scratch wound-healing assay. In conclusion, our results will support further studies to increa…
Recensione di La questione mediterranea
2019
Review of the book La questione mediterranea, by Ian Chambers and Marta Cariello, where the mediterranean is like a fluid archive, which is never intended as a collector of dead objects, but unlike traces, removed but never dormant, consisting of cultural practices.
Ética de la asistencia primaria a los niños de procedencia internacional
2012
La inmigración se ha convertido en un fenómeno universal. Uno de sus efectos es el incremento de los niños de procedencia internacional en las consultas de pediatría. Se trata de una población doblemente vulnerable, por tratarse de niños y por proceder de contextos culturales extraños a los del país de acogida. Ante esta realidad emergente es imprescindible preguntarse por el tipo de asistencia sanitaria que deben recibir. En el presente artículo se proponen principios éticos de actuación inspirados en las principales normas internacionales sobre bioética y derechos de los niños: principio de vulnerabilidad; principio de respeto y amor, y principio de acceso y atención sanitaria. Finalmente…
Enroling around : Reconfiguring place and space in the wake of a new reception centre in a small rural town
2022
The paper examines how a small rural town Kauhava, Finland, is reconfigured in the wake of a reception centre being established. Drawing on the conceptual toolbox of the sociology of associations, we find that regardless of attitudes towards asylum seekers, people springing into action and enroling others leads to the problematisation and intensification of place. This involves turning public and private spaces into contested places. Competing definitions of community and identity emerge. While new identities are configured, new associations and ways of linking actors and places together also take form. The paper examines how the micropolitics of place and belonging are carried out in pract…
Translating migration: digital narratives, (anti) museums in action and documentaries
2016
This article investigates the modalities through which the migrant crisis is portrayed in the creative artistic sector that, in turn, has accelerated the spread of political participatory and activist movements in the areas of subtitling and amateur translation. This innovative trend involving the sphere of translation has been acting as an important stimulus for the international mushrooming of artistic creativities on public spaces and digital platforms, but also for the formation of new views on translation and interpretation as actively contributing to the reframing of the political aspects of the migrant crisis. Such a counter wave of artistic productions has emerged within a Europe th…
