Phytochemical characterization and biological activities of green tea (Camellia sinensis) produced in the Azores, Portugal
2021
Abstract Background Green tea is not only one of the most widely consumed beverages worldwide, but is also known for its health promoting and therapeutic effects. Green tea is cultivated in areas with high humidity and acidic soils in China, Indonesia and Japan. Those places have well-marked dry and rainy seasons. In opposite, Azores have a climate with constant average annual rainfall and, unlike eastern regions, relatively constant air humidity throughout the year. While a brand implemented on the Portuguese market, the quality of green tea produced in Azores must be guaranteed. Quality control measures based on phytochemical determination of the chemical composition and biological activi…
Tannins from Hamamelis virginiana Bark Extract: Characterization and Improvement of the Antiviral Efficacy against Influenza A Virus and Human Papill…
2014
Antiviral activity has been demonstrated for different tannin-rich plant extracts. Since tannins of different classes and molecular weights are often found together in plant extracts and may differ in their antiviral activity, we have compared the effect against influenza A virus (IAV) of Hamamelis virginiana L. bark extract, fractions enriched in tannins of different molecular weights and individual tannins of defined structures, including pseudotannins. We demonstrate antiviral activity of the bark extract against different IAV strains, including the recently emerged H7N9, and show for the first time that a tannin-rich extract inhibits human papillomavirus (HPV) type 16 infection. As the …

Immunity, resistance and tolerance in bird-parasite interactions.
2013
12 pages; International audience; Interacting pathogens and hosts have evolved reciprocal adaptations whose function is to allow host exploitation (from the pathogen stand point) or minimize the cost of infection (from the host stand point). Once infected, two strategies are offered to the host: parasite clearing (resistance) or withstanding the infection while paying a low fitness cost (tolerance). In both cases, the immune system plays a central role. Interestingly, whatever the defence strategy adopted by the host, this is likely to have an effect on parasite evolution. Given their short generation time and large population size, parasites are expected to rapidly adapt to the environment…
Two Borderline Works: The Miniature Classical Friezes by John Henning
2020
The plaster replicas of two miniaturized reproductions of the Parthenon and Bassae friezes are preserved at the Plaster Cast Gallery of the Department Cultures and Societies of the University of Palermo. The original reproductions were made by the Scottish carver John Henning in the first decades of the 19th century. These artefacts, although they have seldom captured the attention of the archaeologists, are of particular interest and from manifold points of view.
Indirect Catalytic Spectrophotometric Determination of Metamizol Following Oxidation by Lead Dioxide Immobilized in A Polyester Resin Bed
1996
Abstract A spectrophotometric-indirect procedure for the determination of metamizol is described. The method is based on the reaction of the drug in a solid-phase (lead dioxide immobilized in a polyester resin bed) in acidic media (perchloric acid 0.01 M as carrier). The lead dioxide reactor provides simultaneously an effective oxidation of the drug and a controlled liberation of Pb(II) which acts as catalyst on the reaction pyrogallol red-potassium persulphate; the oxidation of the red pyrogallol results in a less coloured solution. The decreased red colour (negative FIA peaks) is monitored at 520 nm. The calibration graph is linear in the interval 2–16 ppm in metamizol. The relative stand…
Population Decline of the Capercaillie Tetrao urogallus aquitanicus in the Central Pyrenees
2020
El seguimiento a largo plazo de las aves amenazadas es esencial para estimar las tendencias poblacionales e identificar las posibles causas de declive, siendo particularmente importante en el caso de las aves alpinas que habitan en areas montanosas en los limites de su area de distribucion. Analizamos la tendencia poblacional del urogallo en los Pirineos centrales espanoles a partir de investigaciones realizadas entre 2000 y 2017. Encontramos un declive significativo de la poblacion (alrededor del 58%) en el numero de aves contadas en las areas de exhibicion (lek). la mayoria de los urogallos habitan bosques de coniferas de pino negro con una cobertura elevada de arandano y rododendro en el…

La definizione della possessio nel Festo Farnesiano fra tradizione manoscritta, edizioni e interpretazione storiografica
2016
La comprensione della definizione di possesso fornita da Elio Gallo (ap. Fest., p. 260-262 L.) dipende dalla ricostruzione del testo tramandato nel Codice Farnesiano (Napoli, Biblioteca Nazionale, Neap. IV A 3). Una nuova analisi della tradizione manoscritta compiuta in una più ampia prospettiva consente di verificare se e in quale misura la circolarità ermeneutica ha condizionato le edizioni a stampa su cui sono basate le varie interpretazioni di tale definizione. The understanding of the definition of possession by Aelius Gallus (ap. Fest., p. 260-262 L.) depends on the reconstruction of the text preserved in the Codex Farnesianus (Napoli, Biblioteca Nazionale, Neap. IV A 3). A new analys…
Recensione di I territori marginali e la quarta rivoluzione urbana. Il caso della Gallura
2019
La recensione commenta un volume che presenta i risultati di un'unità di ricerca loacale, quella dell'Università di Sassari-Alghero, nel quadro di una ricerca PRIN nazionale sul tema della Postmetropoli che ha visto come capofila il Politecnico di Milano. Il volume fa parte di una serie di altri volumi, curati da altre sedi locali, che nell'insieme restituiscono i risultati della ricerca. The review discusses on a book that presents the results of a loacal research unit,in the University of Sassari-Alghero, as part of a national PRIN research on the theme of the Postmetropolis, as Soja wrotes, with the Polytechnic of Milan as the leader. The volume is part of a series of volumes, edited by …
