3D in Suspension versus 2D in Adhesion: molecular profiles in stemness and mesenchymal differentiation of Spheroids from Adipose-derived Stem Cells
2021
Purpose: Adipose stem cells (ASCs) represent a reliable source of stem cells with a widely demonstrated potential in regenerative medicine and tissue engineering applications. New recent insights suggest that three-dimensional (3D) models may closely mimic the native tissue properties; spheroids from adipose derived stem cells (S-ASCs) exhibit enhanced regenerative abilities compared with those of 2D models. Stem cell therapy success is determined by “cell-quality”; for this reason, microRNA profiles, the involvement of stress signals and cellular aging need to be further investigated. Material and Methods: Adipose tissue was collected from healthy individuals, 44 females and 17 males, afte…
Neanderthal firewood management: Evidence from Stratigraphic Unit IV of Abric del Pastor (Eastern Iberia)
2015
This paper presents anthracological data from Abric del Pastor (Alcoi, Spain), a Middle Paleolithic rock shelter site. Analysis of 1077 wood charcoal remains from Stratigraphic Unit IV (S.U. IV), collected within archaeological combustion structures and from loose sediment outside of structures, allowed us to characterise the local landscape, as well as to approach the interaction between Neanderthal groups and their local environment. Taxonomic identification suggests that firewood was gathered from nearby sources, with predominance of juniper (Juniperus sp.) followed by thermophilous shrubby taxa. Additional analysis focussing on post-depositional processes affecting charcoal have shown f…
Archaeological construction and its relationship with place: the theme of shelters / Costruito archeologico e rapporto con il luogo: il tema delle co…
2013
Il rapporto con il luogo costituisce il punto di partenza per l’identificazione e la conoscenza di qualunque reperto archeologico. Nel caso di costruzioni archeologiche, tale rapporto si configura come insieme complesso di relazioni, da leggere con approccio sistemico e interdisciplinare, che risulta determinante anche sulla permanenza delle testimonianze del passato. Il tema delle coperture, oggetto di numerosi approfondimenti negli ultimi decenni, si presta a una lettura del modo in cui si è evoluto l’approccio al costruito archeologico il rapporto con il luogo, in funzione delle concezioni culturali e della maturazione della consapevolezza delle tante specificità in gioco, che si possono…
Urban Archaeology Enhancement / Valorizzare l’archeologia urbana
2013
Molte città europee convivono, in forme diversamente evidenti, con un costruito archeologico custodito nel suolo in cui si è sedimentato lo scorrere del tempo. Ciò rende l’archeologia urbana un tema di rilevante interesse, anche perché solleva questioni di elevata complessità, che richiedono una specifica attenzione che coinvolga sia la consapevolezza della storia e la volontà di conservarne e comunicarne le tracce, sia il dinamismo tipico delle trasformazioni contemporanee. I saggi raccolti in questo volume affrontano il tema sotto gli aspetti tecnologici, strutturali, conservativi, museologici e museografici, seguendo un’articolazione di esempi che comprende casi di costruzioni archeologi…
Architettura emergenziale: buone pratiche esecutive
2022
This paper provides a comparative overview of different types of (temporary) shelters that have recently been used in various field locations in response to a forced displacement due to disastrous events. In particular, possible strategies useful to increase the sustainability of the humanitarian response and reduce the carbon footprint, while ensuring the adequacy and suitability of the shelters themselves, are here explored. This study investigates a systematic design framework that is often constrained by many obstacles such as the limited availability of low-cost materials, and a lack of local labour experience. To reduce the negative impact of a disaster, especially in the developing c…
A multiproxy record of palaeoenvironmental conditions at the Middle Palaeolithic site of Abric del Pastor (Eastern Iberia)
2019
This paper presents a multiproxy palaeoenvironmental study from Abric del Pastor (Alcoy, Spain), a rock shelter which has yielded evidence for Middle Palaeolithic human occupation. The sedimentary sequence has been analysed for lipid biomarker n-alkane abundances (ACL, CPI), compound specific leaf wax δH and δC, and bulk organic geochemistry (TOC, %N, %S), providing a record of past climate and local vegetation dynamics. Site formation processes have been reconstructed through the application of soil micromorphology. Analyses of anthracological, microvertebrate and macrofaunal assemblages from selected subunits are also presented here. Our data indicates that a variable climate marked by pr…
Villages, Caves, Sheds and Shelters during the Bronze Age: the Contribution of Cerro de los Purgaticos (La Canyada, Alicante)
2018
En este artículo se presentan los resultados de la excavación arqueológica efectuada en el pequeño yacimiento de la Edad del Bronce del cerro de los Purgaticos (La Canyada, Alicante). A partir de sus características esenciales se discute la hipótesis que viene a considerar que, además de asentamientos o lugares de residencia habituales durante la Edad del Bronce en las tierras del levante peninsular, una parte de los yacimientos de pequeño tamaño pudieron ser establecimientos complementarios en la gestión organizativa y productiva en los espacios apropiados. A las cuevas empleadas en muy diversos menesteres, ahora debemos contemplar que algunos enclaves al aire libre también pudieron funcio…
Short-term responses of soil macroarthropod community to clear felling and alternative forest regeneration methods
2003
Abstract We studied the influence of clear felling and new alternative forest regeneration methods on soil macroarthropods during the first 3 years after the harvesting. We focused on changes in the abundances of functional groups, and community structure at the levels of species (Coleoptera) or higher taxa. The experiment was carried out in central Finland in spruce (Picea abies (L.) Karst.) stands on 1 ha study plots. The following five treatments were used in addition to the untreated controls: (1) selection felling (70% of the stand volume retained), (2) gap felling (0.1–0.2 ha gaps felled), (3) gap felling with site preparation, (4) retention felling (small groups of trees retained on …
Limited behavioural effects of ocean acidification on a Mediterranean anemone goby (Gobius incognitus) chronically exposed to elevated CO2 levels
2022
An in situ reciprocal transplant experiment was carried around a volcanic CO2 vent to evaluate the anti-predator responses of an anemone goby species exposed to ambient (∼380 μatm) and high (∼850 μatm) CO2 sites. Overall, the anemone gobies displayed largely unaffected behaviors under high-CO2 conditions suggesting an adaptive potential of Gobius incognitus to ocean acidification (OA) conditions. This is also supported by its 3-fold higher density recorded in the field under high CO2. However, while fish exposed to ambient conditions showed an expected reduction in the swimming activity in the proximity of the predator between the pre- and post-exposure period, no such changes were detected…
Pressure-Knapping Blade Production in the North-Western Mediterranean Region During the Seventh Millennium cal B.C.
2012
A review of selected Mesolithic blade and trapeze complex series in the north-western Mediterranean reinforces the hypothesis of a common use of pressure techniques for bladelet production during the seventh millennium cal B.C. This paper deals with the specificity and variability of these techniques and the consistency of the blade production methods. Mesolithic pressure technique seems to have been quickly diffused within the western Mediterranean basin, earlier than the spread of Early Neolithic communities in the same area. It then proceeded from a regional development, distinct from the Mesopotamian and Anatolian cores.
