Decision support system for accessing costs and risks of connected and autonomo...
Rodrigues, Mónica; Costa, Maria C.; Bandeira, Jorge M.A predicted increase of connected autonomous vehicles (CAVs) in our roads paved the way for new opportunities and challenges towards the promotion of sustainable mobility. However, the impacts of CAVs on the road environment and its implications are widely dependent on technological choices and public policy [1,2]. Therefore, this research (PhD Workplan) intends to assess whether CAVs could be effective mobilit...
Zantaz honey “monoflorality”: Chemometric applied to the routinely assessed par...
Elamine, Youssef; Lyoussi, Badiâa; Anjos, O.; Estevinho, Letícia M.; Aazza, Smail; Carlier, Jorge D.; Costa, Maria C.; Miguel, Maria GraçaThe comparison of Zantaz honey samples harvested in Morocco in two different years was performed through chemometric analysis of routinely assessed parameters. The objective was to study how the pollen profile of this newly reported honey shapes its physicochemical characteristics as well as to determine its monoflorality threshold, which has not yet been defined. The predominance of B. spinosum pollen was conf...
Physicochemical characterization and antioxidant activity of honey with Eragros...
AAZZA, Smail; Elamine, Youssef; EL-GEUNDOUZ, Soukaina; Lyoussi, Badiaa; Antunes, Maria Dulce; Estevinho, Leticia M.; Anjos, Ofélia; Carlier, JorgeThis study aimed to characterize the pollen and physicochemical profiles, and to evaluate the antioxidant capacity of six samples of Moroccan honey. The pollen grains of Eragrostis spp. were predominant in all samples (from a minimum of 46.581.59% to 72.72 +/- 2.43% as a maximum), exceeding the minimum (generally 45%) required for the monoflorality nomination of a honey sample, and suggestion a case of newly re...
MMP-9/RECK imbalance: a mechanism associated with high-grade cervical lesions a...
Discacciati, Michelle G.; Gimenes, Fabrícia; Pennacchi, Paula C.; Flores, Fernanda Faião; Zeferino, Luiz C.; Derchain, Sophie M.; Teixeira, Júlio C.BACKGROUND: Matrix metalloproteinases (MMP) are important enzymes in the tumor microenvironment associated with progression of cervical intraepithelial neoplasia (CIN) toward squamous cell carcinoma (SCC) of the cervix. However, the role of MMPs in the inflammatory process associated with Chlamydia trachomatis infection concomitant with the carcinogenic process driven by HPV has not yet been addressed. In the p...
Biotechnologically obtained nanocomposites: A practical application for photode...
da Costa, Joao Pinto; Girao, Ana V.; Monteiro, Olinda C.; Trindade, Tito; Costa, Maria C.This research was undertaken to determine the potential of biologically obtained ZnS-TiO2 nanocomposites to be used as catalysts in the photodegradation of organic pollutants, namely, Safranin-T. The photocatalysts were prepared by modifying the surface of commercial TiO2 particles with naturally produced ZnS, using sulfide species produced by sulfate-reducing bacteria and metal contaminated wastewaters. Compar...
A bacterial consortium isolated from an Icelandic fumarole displays exceptional...
Alexandrino, Maria; Macías, Francisco; Costa, Rodrigo; Gomes, Newton C. M.; Canário, Adelino V. M.; Costa, Maria C.The soils of three fumaroles and one mining site, all with high metal content, were surveyed for the presence of metal-resistant sulfate-reducing bacteria and their potential application in the bioremediation of acid mine drainages. By means of selective soil enrichments a bacterial consortium was isolated from an Icelandic fumarole that displayed very high sulfate reduction in the presence of a mixture of 0.75...
