Computational Identification of Chemical Compounds with Potential Activity against Leishmania amazonensis using Nonlinear Machine Learning Techniques.
2019
Leishmaniasis is a poverty-related disease endemic in 98 countries worldwide, with morbidity and mortality increasing daily. All currently used first-line and second-line drugs for the treatment of leishmaniasis exhibit several drawbacks including toxicity, high costs and route of administration. Consequently, the development of new treatments for leishmaniasis is a priority in the field of neglected tropical diseases. The aim of this work is to develop computational models those allow the identification of new chemical compounds with potential anti-leishmanial activity. A data set of 116 organic chemicals, assayed against promastigotes of Leishmania amazonensis, is used to develop the the…
An Integrative Approach to Assess the Environmental Impacts of Gold Mining Contamination in the Amazon
2021
As the number of legal and illegal gold mining sites increases in the Andes–Amazonia region, integrative methods to evaluate the effects of mining pollution on freshwater ecosystems are of paramount importance. Here, we sampled water and sediments in 11 sites potentially affected by gold mining activities in the Napo province (Ecuador). The environmental impacts were evaluated using the following lines of evidence (LOEs): water physicochemical parameters, metal exposure concentrations, macroinvertebrate community response (AAMBI), and toxicity by conducting bioassays with Lactuca sativa and Daphnia magna. Dissolved oxygen and total suspended solids were under (130 mg/Ls) quality standards 6…
The role of sustainable agroforestry practices and food consumption to prevent tropical deforestation and increase ecosystem services
2022
Tropical forests harbor most of global terrestrial biodiversity and provide essential ecosystem services, although they have been largely replaced by agricultural activities. Amazon is the largest tropical forest remaining, and cattle ranching and soybean cultivation are by far the greater drivers of deforestation, that together with other few commodities constitutes the main products responsible for the imported deforestation caused by European countries. Agroforestry systems and sustainable intensification are pointed out as solutions to conciliate food production with environmental conservation, thus reviewing the results of studies comparing these practices against conventional ones are…
Il centro commerciale come palinsesto aumentato. Innovazioni nell’edificio pubblico
2018
L’articolo discute alcuni caratteri architettonici del centro commerciale inteso come impianto su cui la riflessione disciplinare può operare nuovi indirizzi di intervento, attraverso una lettura genealogica con particolare riferimento alla pianta. L’ideale dell’open space, ipotesi di totale libertà della pianta senza tramezzi divisori, viene acquisito negli ultimi trent’anni del Novecento dagli architetti radicali. Le supersuperfici neutre che fanno riferimento al supermercato, lo promuovono a sintesi di ogni spazialità perché ciò sia un monito, espresso attraverso l’evocazione di un universo distopico in cui ogni significato sociale si esprimerà attraverso la produzione e la vendita delle…
“Pensare con” i popoli indigeni dell’Amazzonia i rapporti tra uomo e cosmo
2020
Despite the devastation produced by centuries of European colonization, Amerindian societies have maintained worldviews and conceptions of humanity which present a great richness, originality and variety. As shown both by Lévi-Strauss (1992) and, in a study perspective closer to Eliade's approach, by Sullivan (1988), they share some common characteristics which it is useful to compare, by difference and analogy, with those of Euro-Western cosmologies. As Viveiros de Castro argued with specific reference to the indigenous cosmologies of the Amazon, the importance of the aspects of relationality of reality, its eminently transformative dynamic nature, the ontological multiplicity of its compo…
Soil Bacterial Community Along an Altitudinal Gradient in the Sumaco, a Stratovolcano in the Amazon Region
2022
Our study is a pioneering exploration of the microbiome in the soil of the Sumaco stratovolcano and an assessment of the effects of an elevational gradient and related physicochemical soil parameters on richness and community structure. The Sumaco, as an isolated Amazonian stratovolcano, may be among one of the least studied ecosystems in Ecuador and perhaps the Amazon region. Universal patterns remain unresolved or available information inconclusive to establish a supported consensus on general governing processes by which elevation and its associated environmental gradients may determine the microbial richness and community structure. We tested a recent proposal on how microbial diversity…
I sapori dei tatuaggi nell'Amazzonia indigena
2018
Through an analysis of some ethnographic examples (Matis, Akawaio,Guayaki, Cayabi), the chapter shows how in Indigenous Amazonia tattooing was connected in multiple ways to cultural conceptions regarding both the fabrication of the person and the classifications of world components, in which complex systems of correspondence between diverse domains organize people's experience and thought.

United by the same concern. Ecumenical impulses of Pope Francis in the context of integral ecology
2020
Jednym z istotnych zadań Kościoła w porządku doczesnym jest troska o dzieło stworzenia i samego człowieka, a czasami wręcz obrona ludzkości przed zagrożeniami, wyzwolonego od jakichkolwiek odniesień etyczno-moralnych, postępu technicznego. Troska o wspólny dom nie jest tyko domeną Kościoła katolickiego, również inne kościoły i wspólnoty chrześcijańskie – podobnie jak i inne religie, dokonują refleksji nad zagadnieniami związanymi z degradacją środowiska ludzkiego i naturalnego (LS, 7). Celem artykułu jest próba dostrzeżenia i analizy ekumenicznych impulsów papieża Franciszka w kontekście całościowej ekologii, uwzgledniającej wzajemne powiązania różnych wymiarów rzeczywistości. Dlatego w tra…
A SOLUTION TO THE DILEMMA BETWEEN R&D EXPANSION AND THE PRODUCTIVITY DECLINE: LESSONS FROM THE R&D MODELS IN AMAZON AND FINLAND
2019
As a consequence of the two-faced nature of information and communication technology (ICT), a majority of ICT leaders have been confronting the critical problem of a dilemma between R&D expansion and productivity decline in the digital economy. However, Amazon has been able to accomplish a skyrocketing increase in R&D and market capitalization. Finland has also accomplished balanced advancement not only of welfare but also economic resurgence. This paper attempted to elucidate the miracle of two ICT leaders. By means of a comparative empirical analysis of respective development trajectories, the sources of their success were analyzed thereby the comparative advantage and disadvantag…
