An extra-urban soil cadastre for Italy: a first guide for the introduction of soil information
2020
Assuming a positive outcome of the parliamentary procedure for laws and, thus, the transformation of the official cadastre for buildings and land into a soil cadastre (urban, extra-urban and cadastre for the conservation of natural or semi-natural soil diversity) would start a new era for pedology. Finally, after many decades of activity to expand soil culture in Italy, almost all Italian families would be in contact with a soil specialist. Land use and redefined plots would be handled with greater care and responsibility. Experts in agricultural and forestry and biodiversity conservation would have a new impetus in their activity. Furthermore, economists will also have to address new issue…
Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Crustacea, Branchiopoda, Anostraca): On the verge of extinction?
2016
The province of Cadiz (South of Spain) hosts the only known locality in the world of Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Anostraca). In this paper, the geographical distribution of the species based on published sampling data focused on large branchiopods and temporary pools in Andalusia and the entire Iberian Peninsula is assessed. The current situation is summarized based on the threats to their survival, which are mainly related to habitat alteration. In the Iberian Peninsula, at least 1,648 bodies of water (about 720 in Andalusia) have been explored. Prevalence data suggest that L. baetica is a rare species (localities with presence / sample locations = 6.07 . 10-4). The …
Strategie di difesa in risposta a stress in embrioni di riccio di mare: L'embrione di riccio di Paracentrotus lividus come modello sperimentale per l…
2013
Negli ultimi decenni, grazie alle nuove tecnologie e alla maggiore disponibilità di strumenti di ricerca, il campo riguardante lo studio delle strategie di difesa attivate nella risposta a stress, compresi i meccanismi di apoptosi e autofagia, è divenuto molto ampio ed è in continua espansione. Sin dagli albori della Biologia, gli studi condotti sul modello sperimentale di riccio di mare hanno permesso di ottenere conoscenze di base, spesso applicabili ad altri modelli biologici. I dati riportati nel presente libro dovrebbero aiutare a far luce sui meccanismi di difesa che le cellule sono in grado di attivare, in caso di necessità, se esposte a sfavorevoli condizioni ambientali. Le osservaz…
Contactus adherens, a special type of plaque-bearing adhering junction containing M-cadherin, in the granule cell layer of the cerebellar glomerulus.
1995
In the glomeruli of the granule cell layer of mammalian cerebellum, neuronal extensions are interconnected by numerous small, nearly isodiametric (diameters up to 0.1 micron), junctions previously classified as puncta adherentia related to the vinculin-containing, actin microfilament-anchoring junctions of the zonula adherens of epithelial and certain other cells. Using immunofluorescence and immunoelectron microscopy, we have found, however, that these junctions are negative for E- and VE-cadherin, for desmosomal cadherins, and also for vinculin, alpha-actinin, and desmoplakin, but they do contain, in addition to the protein plakoglobin common to all forms of adhering junctions, the plaque…

Desmosomes: interconnected calcium-dependent structures of remarkable stability with significant integral membrane protein turnover
2002
Desmosomes are prominent cell adhesion structures that are major stabilizing elements, together with the attached cytoskeletal intermediate filament network, of the cytokeratin type in epithelial tissues. To examine desmosome dynamics in tightly coupled cells and in situations of decreased adhesion, fluorescent desmosomal cadherin desmocollin 2a (Dsc2a) chimeras were stably expressed in human hepatocellular carcinoma-derived PLC cells (clone PDc-13) and in Madin-Darby canine kidney cells (clone MDc-2) for the continuous monitoring of desmosomes in living cells. The hybrid polypeptides integrated specifically and without disturbance into normal-appearing desmosomes that occurred in associati…
Steroid fingerprints: Efficient biomarkers of human decomposition fluids in soil
2018
Abstract The decomposition of animal and human cadavers can lead to comprehensive chemical and biochemical changes in soil, which can provide helpful information for the analysis of archaeological and crime scenes. The current study focused specifically on the concentration and distribution patterns of steroids in soil with the aim of assessing their suitability for demonstrating the presence of human decomposition products. Soil samples were collected from a forensic site where a human corpse had been lying on the soil surface for 18 days. Total organic carbon (TOC) and steroid concentrations were analysed in soil samples taken from beneath the body at the time the corpse was removed and a…
TGFβ-induced EMT requires focal adhesion kinase (FAK) signaling
2007
The epithelial-to-mesenchymal transition (EMT) is a crucial process, occurring both during development and tumor progression, by which an epithelial cell undergoes a conversion to a mesenchymal phenotype, dissociates from initial contacts and migrates to secondary sites. We recently reported that in hepatocytes the multifunctional cytokine TGFβ induces a full EMT characterized by (i) Snail induction, (ii) E-cadherin delocalization and down-regulation, (iii) down-regulation of the hepatocyte transcriptional factor HNF4α and (iv) up-regulation of mesenchymal and invasiveness markers. In particular, we showed that Snail directly causes the transcriptional down-regulation of E-cadherin and HN…
Resistencia erosiva de composites dentales directos e indirectos CAD/CAM
2020
Resistencia erosiva de composite directos e indirectos CAD/ CAM El propósito de este estudio in vitro es investigar la resistencia erosiva en las diferentes propiedades de los composites tipo directo e indirecto CAD/CAM. Se emplearon seis composites, tres de tipo directo FILTEK Supreme XTE, BRILLIANT EverGlow, GrandioSo y tres indirectas para CAD/CAM Lava Ultimate, BRILLIANT Crios, Grandio Blocs fueron empleadas. Se dividieron aleatoriamente, en un grupo control y otro con jugo gástrico simulado. Se analizó la microdureza Vickers, Resistencia a la flexión de tres puntos ( Módulo de Weibull), desgaste y la topografía superficial con un microscopio de fuerza atómica (AFM). Los datos fueron an…
