A systematic review and meta-analysis on the effectiveness of xenograft to prevent periodontal defects after mandibular third molar extraction.
2021
Background To evaluate the use of guided bone regeneration with xenograft to prevent periodontal defect in the distal aspect of the second molar after the surgical removal of the mandibular third molar. Material and Methods Three electronic databases (Pubmed, Cochrane Library and Scopus) were searched in April 2020. Randomized clinical trials in non-smokers and healthy patients, with at least six months follow-up, comparing periodontal probing depth, clinical attachment level, alveolar bone level and adverse events were selected by two independent investigators. The risk of bias assessment of the selected studies was evaluated by means of the Cochrane Collaboration’s Tool. Finally, a meta-a…
Amatrice: storia e storie di una comunità elastica
2020
Il contributo ricostruisce la storia del patrimonio gastronomico amaticiano: una storia di relazioni transcalari legate al lungo processo di emigrazione che nei secoli ha portato la comunità amatriciana a trasferirsi a Roma. Si ripercorre in che modo la comunità abbia costruito la tua tradizione gastronomica - intesa come patrimonio culturale, oltre che economico - nella relazione mobile tra più luoghi. Un processo di costruzione di simboli e capitali collettivi fortemente transcalare che affonda le radici nell'origine transumante della comunità amatriciana, di cui il volume nel complesso si occupa. Infine, facendo riferimento al presente post-sisma, il contributo discute criticamente il ru…
Recent patents and advances in hepatocyte-like cells differentiation by mesenchymal stem cells
2013
Chronic liver diseases constitute one of the main causes of death in western countries. Orthotopic liver transplantation still remains the final therapeutic approach to these diseases, but alternative therapeutic strategies are actively researched. Hepatocyte transplantation is considered a promising approach, even if this technique presents many limitations. These factors boosted the research for alternative cell sources to derive functional hepatocytes. In the last years, research on basic biology and differentiative ability of adult, embryonic and perinatal stem cells has constantly increased. The term "perinatal" indicates stem cell populations derived from foetal sources such as placen…
The erythropoietin and regenerative medicine: a lesson from fish
2009
Background Erythropoietin (EPO), the main haematopoietic growth factor for the proliferation and differentiation of erythroid progenitor cells, is also known for its angiogenic and regenerative properties. Materials and methods In this study, we aimed to test the regenerative effects of EPO administration in an experimental model of Sea bass (Dicentrarchus labrax) subjected to amputation of the caudal fin. Results Erythropoietin-treated fishes (3000 UI of human recombinant EPO-alpha immediately after cutting and after 15 days) showed an increased growth rate of their fins compared with those untreated (ANOVA variance: P :0 AE01 vs. P :0 AE04). By analysing fin length at established times (1…
The Mediterranean anthozoan Anemonia viridis (Forsskål, 1775) for the study of inflammation and regeneration
2020
Regenerative capability in anthozoans is an important adaptive strategy for their survival to environmental disturbance of natural and anthropogenic origin such as predation or anchoring, that can cause injuries or removal of entire parts of the animal body, and it can be also considered indirectly a further tool of innate immune system. In the context of “self”-“non self” recognition, is significant the interaction with the endosymbiont of the genus Symbiodinium and the recognition of pathogens and foreign agents capable of invading the injured tissues. From these premises and the growing stressors that can cause injuries, it is significant to understand how species respond to physical dam…
Basic approach of inflammation, injury and regeneration in Anemonia viridis
2020
The potential for tissue regeneration is a powerful adaptive strategy essential to the survival of individuals. It allows to face wounds or loss of body parts induced by predation, anthropic actions or environmental factors. In light of the high probability of increasing levels of disturbances caused by injuries and the increasing possibility of invasion of microbes and foreign agents in the tissues of anthozoans, it is crucial to determine how the species respond to wounds and physical damage and understand the capacity of recovering and tissues regeneration. From this point of view, the regeneration capacity of Anthozoa it could be considered an additional arm of innate immune defence and…
Augmented Cities in the Neoanthropocene
2021
Contemporary cities could be considered vibrant organisms of places and communities, of data and information, of sensors and actuators, and of actions and reactions generated by people and environment both. Cities must be more responsive to our behavioral changes, enabling devices for enhancing our contemporary life. We would be able to build amore efficient urban environment, able to sense, to understand and to act every day and for everyone. In the post-city age and beyond the smart city, Augmented City is a new paradigm that perceives the demands of more networked, knowledge-based, and creative society that answers to the global change by a new circular metabolism. The Augmented City is …
Lack of Dystrophin Affects Bronchial Epithelium in mdx Mice
2016
Mild exercise training may positively affect the course of Duchenne Muscular Dystrophy (DMD). Training causes mild bronchial epithelial injury in both humans and mice, but no study assessed the effects of exercise in mdx mice, a well known model of DMD. The airway epithelium was examined in mdx (C57BL/10ScSn-Dmdmdx) mice, and in wild type (WT, C57BL/10ScSc) mice either under sedentary conditions (mdx-SD, WT-SD) or during mild exercise training (mdx-EX, WT-EX). At baseline, and after 30 and 45 days of training (5 d/wk for 6 weeks), epithelial morphology and markers of regeneration, apoptosis, and cellular stress were assessed. The number of goblet cells in bronchial epithelium was much lower…
The Waterfront Theorem: an integrated and creative planning approach
2016
Waterfronts are sensitive interfaces between land and sea, creative interfaces between urban and environmental components, social interfaces between nodes and networks. They not only coincide with the areas of infrastructure that are gathering on the coast, not only with the shoreline or the environmental components of the coastal territories. They are hired by the project as complex interaction of crossing flows, stratified identity of urban communities: fundamental element of the environmental system, synthesis of landscape, space and community, a place of solidification of the identity of the social, cultural and economic community (Carta, 2009). The management of urban interface of wate…
