Non-pharmacological measures implemented in the setting of long-term care facilities to prevent SARS-CoV-2 infections and their consequences: a rapid…
2021
Background Starting in late 2019, COVID-19, caused by the novel coronavirus SARS-CoV-2, spread around the world. Long-term care facilities are at particularly high risk of outbreaks, and the burden of morbidity and mortality is very high among residents living in these facilities. Objectives To assess the effects of non-pharmacological measures implemented in long-term care facilities to prevent or reduce the transmission of SARS-CoV-2 infection among residents, staff, and visitors. Search methods On 22 January 2021, we searched the Cochrane COVID-19 Study Register, WHO COVID-19 Global literature on coronavirus disease, Web of Science, and CINAHL. We also conducted backward citation searche…

Guinea is one of the West African countries where fertility is still high and declining little, with a worrying health situation (maternal and infant mortality levels among the highest in the world). The level of demographic growth (2.5% per year on average) associated with the low level of socioeconomic development of the country seems difficult to reconcile with the satisfaction of the objectives of sustainable development and thus makes the control of fertility a major challenge.Despite the political will displayed since the early 1980s, the adoption of a national population policy declaration in 1992 and a reproductive health policy in 2001 and the Government's efforts to promote Family…
Ostacoli e determinanti dell’innovazione: un’analisi sulle imprese siciliane di successo
2010
Utilizzando i dati raccolti con un'indagine diretta presso un campione molto esteso di imprese siciliane di successo, si analizza la percezione degli ostacoli a innovare e le principali determinanti che contribuiscono a spiegare il fenomeno dell'innovazione in Sicilia
A Cross-Regional Exploration of Barriers to the Adoption and Use of Electronic Meeting Systems
2007
Originally published in the journal Group Decision and Negotiation: http://www.springerlink.com/content/100270/ Electronic Meeting Systems (EMS) are intended to support group collaboration in completing tasks. While there have been many case studies and laboratory experiments on how EMS can support group tasks, large scale macro investigations exploring EMS adoption and use have been practically non-existent. Furthermore, while several barriers to EMS adoption and use have been suggested, their validation across organizations remains unexplored. We undertook a global initiative to explore information technology support for task-oriented collaboration in the US, Australia, Hong Kong, and Nor…
Electric Vehicles and Psychology, Part 2
2021
This paper presents the main psychological attitudes influencing the transition from conventional ICEV to BEV, and it is the continuance of Electric vehicles and psychology, part 1, [1]. This part faces the range anxiety problem, the risk of explosion of batteries, the autonomous silver vehicles and the experience of driving electric vehicles. If the reader is looking for simple answers, the author does not recommend the subsequent reading, since few paradoxes will be solved.

On the search of the ideal barrier membrane for guided bone regeneration
2018
Background GBRs are essential procedures in implant dentistry and periodontology where barrier membranes play an important role by isolating soft tissue and allowing bone to grow. Not all membranes function the same way, as they differ from their origin and structure, it is important to understand how membranes behave and differ one from others in order to achieve a predictable treatment. Material and methods A systematic search on Medline by two independent reviewers was performed for articles published until July 2017 reporting the characteristics or properties of barrier membranes. The question that preceded the search was designed according to PICO rules. Results A total of 124 articles…
Effect of endothelial cell heterogeneity on nanoparticle uptake.
2020
Endothelial cells exhibit distinct properties in morphology and functions in different organs that can be exploited for nanomedicine targeting. In this work, endothelial cells from different organs, i.e. brain, lung, liver, and kidney, were exposed to plain, carboxylated, and amino-modified silica. As expected, different protein coronas were formed on the different nanoparticle types and these changed when foetal bovine serum (FBS) or human serum were used. Uptake efficiencies differed strongly in the different endothelia, confirming that the cells retained some of their organ-specific differences. However, all endothelia showed higher uptake for the amino-modified silica in FBS, but, inter…
