No evidence of an immune adjustment in response to a parasitoid threat in Lobesia botrana larvae.
2017
5 pages; International audience; Immune function is a key determinant of an organism's fitness, and natural insect populations are highly variable for this trait, mainly due to environmental heterogeneity and pathogen diversity. We previously reported a positive correlation between infection prevalence by parasitoids and host immunity in natural populations of the vineyard pest Lobesia botrana. Here, we tested whether this correlation reflects a plastic adjustment of host immunity in response to the local presence of parasites. To this end, we measured immunity of non-parasitized L. botrana larvae exposed, respectively, to one of the two most common species of parasitoids in vineyards, over…
Egeria. Monuments of Faith in the Medieval Mediterranean
2009
Schede tecniche con illustrazioni di 10 monumenti mobili dell'arte religiosa bizantina conservati in Italia e attinenti al tema del pellegrinaggio.
Tempo e spazio nelle feste ebraiche
2014
In relazione al tema del convegno viene analizzata la concezione del pellegrinaggio e del santuario all'interno dell'ebraismo. Le riflessioni partono dal chiarimento del rapporto tempo-spazio nelle feste ebraiche.
The transmembrane Bax inhibitor motif (TMBIM) containing protein family: Tissue expression, intracellular localization and effects on the ER CA2+-fil…
2015
Abstract Bax inhibitor-1 (BI-1) is an evolutionarily conserved pH-dependent Ca2+ leak channel in the endoplasmic reticulum and the founding member of a family of six highly hydrophobic mammalian proteins named transmembrane BAX inhibitor motif containing (TMBIM) 1-6 with BI-1 being TMBIM6. Here we compared the structure, subcellular localization, tissue expression and the effect on the cellular Ca2+ homeostasis of all family members side by side. We found that all TMBIM proteins possess the di-aspartyl pH sensor responsible for pH sensing identified in TMBIM6 and its bacterial homologue BsYetJ. TMBIM1-3 and TMBIM4-6 represent two phylogenetically distinct groups that are localized in the Go…

Data from: Phylogenomics of Lophotrochozoa with consideration of systematic error
2021
Phylogenomic studies have improved understanding of deep metazoan phylogeny and show promise for resolving incongruences among analyses based on limited numbers of loci. One region of the animal tree that has been especially difficult to resolve, even with phylogenomic approaches, is relationships within Lophotrochozoa (the animal clade that includes molluscs, annelids, and flatworms among others). Lack of resolution in phylogenomic analyses could be due to insufficient phylogenetic signal, limitations in taxon and/or gene sampling, or systematic error. Here, we investigated why lophotrochozoan phylogeny has been such a difficult question to answer by identifying and reducing sources of sys…

Identità e alterità. Il lungo viaggio di Gabriella Ghermandi, Cristina Ali Farah, Igiaba Scego, Ornela Vorpsi
2015
L’analisi parallela delle opere di quattro scrittrici della migrazione consente di individuare, nella singolarità delle scritture, una circolarità di discorso sui temi del viaggio e dello spaesamento, del racconto e della lingua.. Il saggio mette in evidenza come lo «statuto relazionale dell’identità» viva in rapporto a quello dell’alterità e si configuri come un’identità multipla che si realizza in uno spazio mobile. Il lungo viaggio di Gabriella Ghermandi, Cristina Ali Farah, Igiaba Scego e Ornela Vorpsi illustra, con diversi esiti, la trasformazione del tema dell’esilio in quello della perenne erranza. Dalla loro esperienza della migrazione, dalla loro condizione nomade, emergono narrazi…
Leggere il viaggio: la prospettiva dei geografi
2020
Il saggio intende approfondire i temi del viaggio e del pellegrinaggio attraverso l'analisi della scrittura letteraria e dei multiformi significati che le due esperienze, quella del viaggio e del pellegrinaggio, rappresentano. Il viaggio è anche l’espressione dell’osservazione diretta, uno dei più importanti metodi dell’indagine geografica che permette fin da piccoli di acquisire la capacità di studiare il paesaggio, l’ambiente e il rapporto individuo-natura. Esso fornisce input di riflessione, stimola domande, pone questioni anche di rilievo globale. Oggetto del viaggio, inteso come esperienza di conoscenza, è spesso il paesaggio, per i Geografi un concetto tanto complesso quanto affascina…
La matriz extracelular: morfología, función y biotensegridad (parte I)
2009
La matriz extracelular (MEC) representa una red tridimensional que engloba todos los órganos, tejidos y células del organismo. Constituye un filtro biofísico de protección, nutrición e inervación celular y el terreno para la respuesta inmune, angiogénesis, fibrosis y regeneración tisular. Y representa el medio de transmisión de fuerzas mecánicas a la membrana basal, que a través de las integrinas soporta el sistema de tensegridad y activa los mecanismos epigenéticos celulares. La alteración de la MEC supone la pérdida de su función de filtro eficaz, nutrición, eliminación, denervación celular, pérdida de la capacidad de regeneración y cicatrización y alteración de la transmisión mecánica o …
