“Serpentone Reload” an Experience of Citizens Involvement in Regeneration of Peripheral Urban Spaces
2015
Suburbs are often very contradictory places. Despite great part of urban population live there, these parts of cities are mostly considered as degradation places. The topic of suburbs regeneration is relevant today. Nevertheless, often expensive interventions implemented by local authorities fail to regenerate their public spaces. This paper presents the experience of “Serpentone reload”, a workshop based on participatory reactivation of abandoned or underused spaces and buildings in “Cocuzzo/Serpentone” neighbourhood in Potenza (Basilicata, Italy). The workshop particularly focused on the reuse of the “Ship”, an underground building, completed in 2010, never used, because it has been perce…
Ecological study of the wood mouse helminth community in a burned Mediterranean ecosystem in regeneration five years after a wildfire
2007
AbstractParasites are used as biological tags in environmental impact studies. However, terrestrial systems in general and small mammals in particular are rarely considered in these ecological studies. Based on the effects of a wildfire which occurred in the Spanish Serra Calderona Natural Park — a typical Mediterranean ecosystem — the regeneration process of the wood mouse population and its helminth community is analysed. A total of 217 individuals of Apodemus sylvaticus were studied in a five year period, from the second to the fifth post-fire year: 152 mice originating from the burned area and 65 from the control — non-burned — area. The helminth community for both burned and non-burned…
The Fluid City Experience: An Update
2016
This chapter describes the actual status of thirteen European cities that become fluid cities through their strategies for urban regeneration. These cities are divided into three groups: the large port-cities, the medium rank “city-port” cities, the riverfront cities. For every city, we define the status of urban environment and population, the trend for port and airport traffic and the strategies for urban regeneration.
Management of liver failure: from transplantation to cell-based therapy
2011
The severe shortage of deceased donor organs has driven a search for alternative methods of treating liver failure. In this context, cell-based regenerative medicine is emerging as a promising interdisciplinary field of tissue repair and restoration, able to contribute to improving health in a minimally invasive fashion. Several cell types have allowed long-term survival in experimental models of liver injury, but their therapeutic potential in humans should be regarded with deep caution, because few clinical trials are currently available and the number of patients enrolled so far is too small to assess benefits versus risks. This review summarizes the current literature on the physiologi…
miR-31-5p Is a LIPUS-Mechanosensitive MicroRNA that Targets HIF-1α Signaling and Cytoskeletal Proteins
2019
The roles of low-intensity pulsed ultrasound (LIPUS) and microRNAs (miRNAs) on hMSCs commitments have already been investigated
MiR-33a Controls hMSCS Osteoblast Commitment Modulating the Yap/Taz Expression Through EGFR Signaling Regulation
2019
Mesenchymal stromal cells (hMSCs) display a pleiotropic function in bone regeneration. The signaling involved in osteoblast commitment is still not completely understood, and that determines the failure of current therapies being used. In our recent studies, we identified two miRNAs as regulators of hMSCs osteoblast differentiation driving hypoxia signaling and cytoskeletal reorganization. Other signalings involved in this process are epithelial to mesenchymal transition (EMT) and epidermal growth factor receptor (EGFR) signalings through the regulation of Yes-associated protein (YAP)/PDZ-binding motif (TAZ) expression. In the current study, we investigated the role of miR-33a family as a (…
Analysis of the use of expansion osteotomes for the creation of implant beds. Technical contributions and review of the literature.
2006
La atrofia ósea severa del maxilar superior compromete e incluso, en ocasiones, impide la colocación de implantes. Con la expansión ósea mediante osteodilatadores se evita usar instrumentos rotatorios, no se produce calor ni se elimina hueso y se simplifica el tratamiento quirúrgico permitiendo la colocación de fijaciones sin recurrir a tratamientos más complejos. Presentamos una revisión de la técnica de expansión maxilar mediante osteodilatadores, describiendo las principales indicaciones, ventajas e inconvenientes de este procediminiento quirúrgico. Sometimes, the severe superior maxillary atrophy compromises and even impide oral implants treatment. The use of rotatory instruments (drill…
Controlling micro-structure to enhance de novo extracellular matrix deposition in elastomeric scaffolds for cardiac tissue regeneration

Correlated response of in vitro regeneration capacity from different source of explants inCucumis melo.
1994
The variation among and within different populations of the regeneration ability from leaf, cotyledon and hypocotyl explants has been studied. A control population and two lines selected by their regeneration capacity from leaf explants were used. Significant differences among the plants of the control population,for the organogenic response, were detected. The regeneration capacity varies depending on the type of explant. Selection in order to improve the regeneration frequency from leaf explants also raises the organogenic response in the other explant types. This result suggests the presence of a partial common genetic system controlling the regeneration frequency of the diverse types of…
The role of competition and rarity in the restoration of a dry grassland in Finland
2001
Semi-natural grasslands have become scarce throughout Europe. Preservation of their plant species requires either the maintenance of the existing grasslands or the creation of new ones. To study the establishment and regeneration ability of plant species typical of dry grasslands we laid out an experiment on a former arable field in central Finland. We compared the success of 13 grassland species both in a theoretical situation with minimal competition and in competition with weeds. More than half of the species used were regionally rare. As a group, grassland plants reached the highest cover in the experimental plots in which outside competition was minimised by weeding. However, the total…
